humans are not necessarily ideal graders: they provide an average of only three minutes of attention per essa

We are talking here about providing a very rough kind of measurement, the assignment of a single summary score on, say, a seventh grader’s essay

“A few years back, almost all states evaluated writing at multiple grade levels, requiring students to actually write,” says Mark D. Shermis, dean of the college of education at the University of Akron in Ohio. “But a few, citing cost considerations, have either switched back to multiple-choice format to evaluate or have dropped writing evaluation altogether.”

As statistical models for automated essay scoring are refined, Professor Shermis says, the current $2 or $3 cost of grading each one with humans could be virtually eliminated, at least theoretically.

the cost of commercial essay-grading software is now $10 to $20 a student per year. But as the technology improves and the costs drop, he expects that it will be incorporated into the word processing software that all students use

As essay-scoring software becomes more sophisticated, it could be put to classroom use for any type of writing assignment throughout the school year, not just in an end-of-year assessment. Instead of the teacher filling the essay with the markings that flag problems, the software could do so. The software could also effortlessly supply full explanations and practice exercises that address the problems — and grade those, too.

“Providing students with instant feedback about grammar, punctuation, word choice and sentence structure will lead to more writing assignments,” Mr. Vander Ark says, “and allow teachers to focus on higher-order skills.”

When sophisticated essay-evaluation software is built into word processing software, Mr. Vander Ark predicts “an order-of-magnitude increase in the amount of writing across the curriculum.”

the essay-scoring software that he and his teammates developed uses relatively small data sets and ordinary PCs — so the additional infrastructure cost for schools could be nil.

the William and Flora Hewlett Foundation sponsored a competition to see how well algorithms submitted by professional data scientists and amateur statistics wizards could predict the scores assigned by human graders. The winners were announced last month — and the predictive algorithms were eerily accurate.

wanted to create a neutral and fair platform to assess the various claims of the vendors. It turns out the claims are not hype.”

In the United States, in institutions ranging from the National Museum of the American Indian in Washington to regional natural history museums, the real arbiters of indigenous history these days are representatives of contemporary tribes. They oversee the display of a museum’s tribal artifacts and reshape accounts of the past, in many cases relying mainly on frayed strands of traumatically disrupted oral traditions. And everything is meant to increase self-esteem with promotional banality.

how different all of this is from images of the indigenous past north of the border! There are few areas where evidence of ancient state-size power exists (mainly in the 2,000-year-old relics of societies that once thrived along the Ohio, Tennessee and Mississippi Rivers). There are few places where cultural continuity is even remotely clear, and where ancient languages are still widely spoken. Even before colonization, cultures disappeared, leaving behind neither oral traditions nor written records. And forced migrations and centuries of warfare so disrupted native traditions that the past now seems little more than an identity-affirming fantasy.

the head of Mexico’s national archaeological administration, explained in her dissertation that it was not easy to balance the needs of archaeologists with a sensitivity toward the local community, which also has its set of demands. “An experienced archaeologist,” she writes, “on hearing ‘the community will decide,’ immediately abandons hope of success.”

Martin Luther King Jr. applied for a permit to carry a concealed firearm in 1956, after his house was bombed. His application was denied, but from then on, armed supporters guarded his home. One adviser, Glenn Smiley, described the King home as “an arsenal.”

Republicans in California eagerly supported increased gun control. Governor Reagan told reporters that afternoon that he saw “no reason why on the street today a citizen should be carrying loaded weapons.” He called guns a “ridiculous way to solve problems that have to be solved among people of good will.” In a later press conference, Reagan said he didn’t “know of any sportsman who leaves his home with a gun to go out into the field to hunt or for target shooting who carries that gun loaded.” The Mulford Act, he said, “would work no hardship on the honest citizen.”

the Gun Control Act of 1968 amended and enlarged it. Together, these laws greatly expanded the federal licensing system for gun dealers and clarified which people—including anyone previously convicted of a felony, the mentally ill, illegal-drug users, and minors—were not allowed to own firearms. More controversially, the laws restricted importation of “Saturday Night Specials”—the small, cheap, poor-quality handguns so named by Detroit police for their association with urban crime, which spiked on weekends. Because these inexpensive pistols were popular in minority communities, one critic said the new federal gun legislation “was passed not to control guns but to control blacks.”

Indisputably, for much of American history, gun-control measures, like many other laws, were used to oppress African Americans.

One prosecutor in the impeachment trial, Representative John Bingham of Ohio, thought that the only way to protect the freedmen’s rights was to amend the Constitution. Southern attempts to deny blacks equal rights, he said, were turning the Constitution—“a sublime and beautiful scripture—into a horrid charter of wrong.”

Whether or not the Founding Fathers thought the Second Amendment was primarily about state militias, the men behind the Fourteenth Amendment—America’s most sacred and significant civil-rights law—clearly believed that the right of individuals to have guns for self-defense was an essential element of citizenship.

In 2008, in a landmark ruling, the U.S. Supreme Court declared that the government cannot ever completely disarm the citizenry. In District of Columbia v. Heller, the Supreme Court clearly held, for the first time, that the Second Amendment guarantees an individual’s right to possess a gun. In an opinion by Justice Antonin Scalia, the Court declared unconstitutional several provisions of the District’s unusually strict gun-control law, including its ban on handguns and its prohibition of the use of long guns for self-defense. Indeed, under D.C.’s law, you could own a shotgun, but you could not use it to defend yourself against a rapist climbing through your bedroom window.

The Fourteenth Amendment illustrates a common dynamic in America’s gun culture: extremism stirs a strong reaction. The aggressive Southern effort to disarm the freedmen prompted a constitutional amendment to better protect their rights. A hundred years later, the Black Panthers’ brazen insistence on the right to bear arms led whites, including conservative Republicans, to support new gun control. Then the pendulum swung back. The gun-control laws of the late 1960s, designed to restrict the use of guns by urban black leftist radicals, fueled the rise of the present-day gun-rights movement—one that, in an ironic reversal, is predominantly white, rural, and politically conservative.

In the 1920s and ’30s, the NRA was at the forefront of legislative efforts to enact gun control. The organization’s president at the time was Karl T. Frederick, a Princeton- and Harvard-educated lawyer known as “the best shot in America”

Frederick’s model law had three basic elements. The first required that no one carry a concealed handgun in public without a permit from the local police. A permit would be granted only to a “suitable” person with a “proper reason for carrying” a firearm. Second, the law required gun dealers to report to law enforcement every sale of a handgun, in essence creating a registry of small arms. Finally, the law imposed a two-day waiting period on handgun sales.

The NRA today condemns every one of these provisions as a burdensome and ineffective infringement on the right to bear arms. Frederick, however, said in 1934 that he did “not believe in the general promiscuous toting of guns. I think it should be sharply restricted and only under licenses.” The NRA’s executive vice president at the time, Milton A. Reckord, told a congressional committee that his organization was “absolutely favorable to reasonable legislation.”

In the 1960s, the NRA once again supported the push for new federal gun laws. After the assassination of President John F. Kennedy in 1963 by Lee Harvey Oswald, who had bought his gun through a mail-order ad in the NRA’s American Rifleman magazine, Franklin Orth, then the NRA’s executive vice president, testified in favor of banning mail-order rifle sales. “We do not think that any sane American, who calls himself an American, can object to placing into this bill the instrument which killed the president of the United States.”

In May 1977, Carter and his allies staged a coup at the annual membership meeting. Elected the new executive vice president, Carter would transform the NRA into a lobbying powerhouse committed to a more aggressive view of what the Second Amendment promises to citizens.

Wayne LaPierre, the current executive vice president, warned members in 1995 that anyone who wears a badge has “the government’s go-ahead to harass, intimidate, even murder law-abiding citizens.”

As the Yale law professor Akhil Reed Amar has observed, “Between 1775 and 1866 the poster boy of arms morphed from the Concord minuteman to the Carolina freedman.”

True, the Founders imposed gun control, but they had no laws resembling Scalia’s list of Second Amendment exceptions. They had no laws banning guns in sensitive places, or laws prohibiting the mentally ill from possessing guns, or laws requiring commercial gun dealers to be licensed. Such restrictions are products of the 20th century. Justice Scalia, in other words, embraced a living Constitution. In this, Heller is a fine reflection of the ironies and contradictions—and the selective use of the past—that run throughout America’s long history with guns.

More money could be saved over the long term, she added, if connecting newly released inmates to services helps to keep them out of jail and reduces visits to emergency rooms, the most expensive form of care.“The ability for us to be able to call up a treatment provider and say, ‘We have this person we want to refer to you and guess what, you can actually get payment now,’ changes the lives of these people,

as important, he said, was the chance to coordinate care for prisoners after their release.About 70 percent of prison inmates in the state have problems with addiction, he said, and 34 percent suffer from mental illness. Without health coverage, inmates leave prison with 30 days’ worth of medication and are then mostly left to their own devices.“If they go off their medication, oftentimes it can once again lead to more criminal activity,” Mr. Raemisch said. “So by keeping them medicated and keeping them mentally healthy, it really helps us in our re-entry efforts.”

As essential as health insurance is for people trying to put together their lives after being incarcerated, the challenge of getting them into treatment, when they often did not have housing or jobs, was “a whole other kettle of fish,”

Barack Obama’s administration, accelerating a process that had begun in the early 1960s under President Kennedy, was centralizing foreign-policy decision making in the White House’s National Security Council, marginalizing the State Department.

Finally, Kerry, a defeated presidential candidate, was devoid of the sexiness that automatically attaches to a figure, like Hillary Clinton, who remains a legitimate presidential prospect

The consensus in Washington was that Kerry was a boring if not irrelevant man stepping into what was becoming a boring, irrelevant job.

Nearly a year into his tenure, Kerry is the driving force behind a flurry of Mideast diplomacy the scope of which has not been seen in years. In the face of widespread skepticism, he has revived the Israeli-Palestinian peace process; brokered a deal with Russia to remove chemical weapons from Syria; embarked on a new round of nuclear talks with Iran, holding the highest-level face-to-face talks with Iranian diplomats in years; and started hammering out a new post-withdrawal security agreement with Afghan President Hamid Karzai.

it will be Kerry who is credited with making the State Department relevant again.

“He’s front and center on all these issues. That clearly represents a very ambitious first year for any secretary of state.”

Kerry has a bad habit of wandering off script. On a trip to Pakistan in August, he created two diplomatic incidents in a single interview. First he said that the Egyptian army was “restoring democracy” when it toppled the country’s democratically elected president.

President Obama had “a timeline” for ending U.S. drone strikes in Pakistan.

he overshot in the opposite direction, promising that any American strike against Syria would be “unbelievably small”—a bit of impressively self-defeating rhetoric that undermined days of administration efforts to argue that a few dozen Tomahawk cruise-missile strikes would be more than what hawkish critics were calling a pointless “pinprick.”

a word that comes up frequently in conversations about Kerry is gasbag. He had few close friends in the Senate, where he served for nearly 30 years. A former diplomat says Kerry’s recent foreign-policy successes have made him more insufferable than ever.

his gaffes are caused by arrogance and indiscipline. They say that even in a city swollen with egotism and pomposity, Kerry stands out.

“Nobody would challenge the notion that he’s been very much a team player and willing to take on really hard assignments from the president and go to the toughest places.”

(In one late-night press conference in Moscow last May, he uttered a staggering 95-word sentence.

“Even as a junior or senior, he was a pompous blowhard,” says someone who attended Yale with Kerry in the 1960s and asked not to be named.

he is not so much arrogant as awkward.

Liberal Democrats call his hawkish views on Syria a betrayal of his antiwar past. Republicans say he is a perennial flip-flopper: he fought in the Vietnam War and then protested against it; he supported the 2003 invasion of Iraq and then opposed it; he tried to negotiate with Bashar al‑Assad in 2009, then compared him to Adolf Hitler—and then reopened the door to negotiating with him again.

Kerry “just can’t dance.”

Washington mandarins dismiss Kerry’s foreign-policy ambitions as grandiose and overweening, especially relative to what America’s diminishing power can achieve after Iraq and Afghanistan

old foreign-policy hands say that instead of acknowledging the limits of American power in the post–Arab Spring Middle East, Kerry looks for misguided ways to apply power the country no longer has.

Current aides argue that Kerry’s recent successes belie the caricatures of him. “Show me where he hasn’t done this job well,” one demanded when I interviewed him in mid-October.

“I would ask John Kerry, ‘How can you ask a man to be the first one to die for a mistake?’ ”

Kerry seem “pompous” is that “oftentimes he tries too hard.” According to Manley and others, Kerry had a knack for walking up to fellow members on the Senate floor at precisely the wrong time.

His enormous ambition motivates him to aim for major breakthroughs despite daunting odds. And his healthy self-confidence allows him to believe that he can convince anyone of virtually anything.

Kerry also has bottomless reserves of patience that allow him to engage for hours in seemingly fruitless negotiations; he persists long past the time others would have given up in exhaustion.

The amount of time he’s spent negotiating with Afghanistan’s Hamid Karzai and Russia’s Sergey Lavrov alone should qualify him for some kind of diplomatic medal of honor.

an indifference to his own political standing.

Political calculations may have constrained the risks Hillary Clinton was willing to take. Kerry, in contrast, no longer needs to heed political consultants. Nor does he need to worry too much about what his detractors say.

“I don’t care at all,” he said. “I could care less about it. You know, David, I ran for president, so I’m not scared of failure.”

secretary of state is the job for which Kerry was born and bred

“I’m not worried about the politics,” Lowenstein recalls Kerry telling him. “I want to get things done.”

Obama, too, no longer has to worry about reelection; concerns about the 2012 election may have limited the president’s own appetite for diplomatic risk taking in the Mideast during his first term.

But his enthusiasm for his current job is unquestionable; one aide told me that he will have to be dragged from the office—fingernails scraping against the floor—at the end of his term.

As a presidential candidate, he had to downplay his obsession with foreign policy and his fluency in foreign languages, for fear that such things would play badly with voters; as secretary of state, he can freely leverage those qualities.

if there is no breakthrough with Iran, or if his efforts to broker peace in Syria fall short, or if the Israeli-Palestinian peace talks founder, history will likely view Kerry as the tragicomic figure his detractors already judge him to be.

“After you lose the presidency, you don’t have much else to lose.”

Following stints as an assistant district attorney and the lieutenant governor of Massachusetts, Kerry would, after his election to the Senate in 1984, go on to serve for 28 years on the same committee he had stood before in 1971, the Senate Foreign Relations Committee

(But for Ohio, where he lost to Bush by 119,000 votes, Kerry would have been president.

But Kerry stepped into the role at a singularly weak moment for the position. For one thing, America, weary after a decade of conflict, is turning inward; activist diplomacy is out of favor. For another, State Department employees I interviewed told me that morale is low.

the department is too hierarchical, inflexible, and risk-averse—and is in danger of becoming even more so in the aftermath of Benghazi.

the intensely controlling Obama administration has centralized foreign-policy decision making in the National Security Council, weakening the State Department.

Just a day after Kerry delivered one of the most impassioned speeches of his career, assailing Assad’s use of chemical weapons on civilians as a “crime against conscience” and sending a clear signal that U.S. air strikes on Syria were imminent, the president announced that missile strikes might in fact not be imminent, and that he would be seeking congressional authorization to attack Syria.

the president risked causing foreign leaders and negotiators to doubt whether any future warnings or statements issued by Kerry were backed by the White House.

Kerry conducted long interviews with every living former secretary of state—Kissinger, George Shultz, Baker, Madeleine Albright, Powell, Condoleezza Rice, and Clinton—and set out to model himself after Shultz, who, in six and a half years serving under Ronald Reagan, was seen as a combination of the two prototypes, both a great diplomat and a good manager.

“I don’t care about risk, honestly,” he said, leaning forward in his chair, spoiling for a fight. “The riskiest thing to do is to not act. I would far rather try and fail than fail not trying.”

When off the record, in relaxed settings, he is refreshingly direct, profane, and insightful, speaking bluntly about the limits of American power and caustically lamenting Washington’s growing paralysis and partisanship

He finishes sentences with phrases such as something like that or that’s about it or thanks, man. Toes tapping, head bobbing back and forth, he speaks with fervor and candor. His tenacity is palpable.

Recent secretaries of state have had different strengths. Henry Kissinger and James Baker, two secretaries who had close relationships with their presidents (Nixon in Kissinger’s case, George H. W. Bush in Baker’s), were powerful bureaucratic players.

But isn’t staking America’s credibility, and his own reputation, on long-odds breakthrough agreements with Tehran or Moscow, or on Israeli-Palestinian peace talks, a dubious exercise, as Obama’s failed first-term efforts at Mideast peace demonstrated?

Colin Powell lost a crucial internal administration battle in failing to halt the Bush White House’s march to war in Iraq—but was adored at the State Department for implementing sweeping administrative reforms.

Clinton embraced a new, Google Hangout era of town-hall diplomacy, and she elevated economic development and women’s issues. She was an architect of the administration’s “pivot to Asia,” and she took risks in supporting the Afghanistan troop surge and the intervention in Libya.

steered clear of the Middle East, delegating special envoys like Richard Holbrooke and George Mitchell to grapple with the Israeli-Palestinian peace process, peace talks with the Taliban

Clinton was much more prudent and careful than Kerry, whom one former State Department official describes as more of a “high-risk, high-reward”

“My view is that she was pretty sheltered,” he told me. “They were not interpersonally pleasant, and they were very protective of her. You can get into a cocoon.”

“My assessment was that she made a calculated political choice not to hang her hat on that thankless task,” Kim Ghattas,

the former secretary would have taken bolder risks but was reined in by the White House—especially during her first couple of years in office, when hostility from the bitter 2008 primary campaign still lingered between the Obama and Clinton staffs.

she actively engaged in Middle East talks, at one point meeting with Israeli Prime Minister Benjamin Netanyahu for seven hours in New York.

Kennan warned Powell about the dangers of traveling too much—of prioritizing activist diplomacy over providing the White House with solid foreign-policy analysis.

Powell gave a copy of Kennan’s letter to Kerry. So far, Kerry is not following the advice. As October came to a close, Kerry had already flown more than 213,000 miles and spent more than 100 days—roughly 40 percent of his time—outside the United States. In his first nine months, he’d traveled more miles than Clinton had in her entire first year in office.

In 2009, he convinced Afghan President Hamid Karzai to consent to a runoff in his country’s disputed presidential election.

2011, he was dispatched to Pakistan after the killing of Osama bin Laden to persuade local officials to return the tail of an American helicopter that had crashed at the site.

cemented Kerry’s bond with Obama was less his diplomatic achievements than his ability to impersonate another tall, wealthy Massachusetts politician with good hair: Kerry served as Mitt Romney’s surrogate during weeks of preparation for the 2012 presidential debates.

Kerry channeled Romney so effectively that, aides to both men say, he got under Obama’s skin.

Kerry agreed that the U.S. should try to revive Middle East negotiations before the Palestinians again pushed for statehood, at the United Nations General Assembly in September 2013.

In private meetings with Israeli Prime Minister Netanyahu and Palestinian President Mahmoud Abbas, Obama pushed for a resumption of negotiations. At a final press conference before returning to Washington, Obama announced that he was handing the pursuit of talks over to Kerry.

“What I can guarantee is that Secretary Kerry is going to be spending a good deal of time in discussions with the parties.”

He met alone with Abbas for two hours in Amman and then flew to Jerusalem to meet with Netanyahu and three of his aides.

Kerry pressed on, returning in April to Jerusalem and Ramallah, the de facto Palestinian capital in the West Bank. After 24 hours of talks with both sides, Kerry held a press conference at the airport in Tel Aviv.

Kerry held three meetings with Netanyahu and Abbas in three days, including one meeting with the Israeli prime minister that lasted six hours, until 3 a.m. On June 29, he canceled a trip to the United Arab Emirates so he could keep talking with Netanyahu and Abbas, raising expectations of a breakthrough. On June 30, he held another press conference at the Tel Aviv airport.

“We started out with very wide gaps, and we have narrowed those considerably.”

Five months into the job, Kerry was off to an ominous start. His wife was in the hospital. Syria was convulsing. Progress toward Israeli-Palestinian talks was stalled. Egypt was burning. And Republican attack ads were making it appear as though the secretary of state had spent the weekend yachting.

Kerry said, according to the aide. “The only thing I’m interested in is a serious negotiation that can lead to a final-status agreement.”

“On behalf of President Obama, I am pleased to announce that we have reached an agreement that establishes a basis for resuming direct final-status negotiations between the Palestinians and the Israelis,” Kerry said, calmly and deliberately. “This is a significant and welcome step forward.” He declined to take questions.

Nine days later, the Israeli cabinet approved the release of the 104 Palestinian prisoners. The next day, Israeli and Palestinian officials arrived in Washington to begin peace talks.

The smallness of his circle of aides, which had been seen early on as a detriment to his management of the State Department, now made it easier to keep information contained.

Working with consultants from McKinsey, diplomats estimated that $4 billion in long-term private investment would flow to the Palestinians in the wake of an agreement.

Palestinian officials appear to have compromised on their demand for a settlement freeze.

From the beginning, Kerry had insisted that the Obama administration not allow a halt in Israeli settlement construction to become a public precondition.

Kerry also reiterated a core argument: the security that Israel currently enjoys is temporary, if not illusory. Without a two-state solution, Israel will face a European-led campaign of delegitimization, a new intifada, and a Palestinian leader far more radical than Abbas.

The crucial concession—the release of the 104 prisoners—came from the Israeli side

“It takes time to listen, it takes time to persuade,” Frank Lowenstein told me. “This is where Kerry’s willingness to stay up all night pays off.”

The U.S. provided nonlethal aid to the opposition, but White House officials were so fearful of American assistance inadvertently falling into the hands of jihadists that the National Security Council Deputies Committee monitored the distribution of the aid in granular detail. Qatar and Saudi Arabia, meanwhile, were funneling cash and weapons to hard-line militants, including Al Nusra Front, an al-Qaeda affiliate.

Russia continued providing Syria with arms and blocking any action by the UN Security Council.

When Putin finally received Kerry, after a three-hour delay, Putin reportedly fiddled continuously with his pen and “more resembled a man indulging a long-ago scheduled visit from the cultural attaché of Papua New Guinea than participating in an urgent summit with America’s top diplomat,”

At a late-night press conference, a beaming Kerry announced that he and Lavrov would co-host a peace conference in Geneva.

“They were great efforts, and again, I reiterate my gratitude to President Putin for a very generous welcome here.”

Earlier, in April, after American intelligence officials had confirmed that Assad had carried out several small-scale chemical-weapons attacks, Obama had reluctantly agreed to mount a covert CIA effort to arm and train moderate rebels.

if the United States did not “impose consequences” for Assad’s use of chemical weapons, the Syrian leader would see it as “a green light for continued CW use.” But the White House did not alter course.

Both Obama and Kerry favored a military response—air strikes—according to a senior administration official. As American intelligence agencies accumulated evidence suggesting that Assad was responsible, Kerry offered to make the public case for strikes. White House officials welcomed the idea and vetted his speeches.

“My vision is that, if you can make peace, if you can get Israel and Palestine resolved and can get the Iranian threat of a nuclear weapon put to bed appropriately—even if Syria didn’t calm down—if you get those two pieces or one piece of that, you’ve got a hugely changed dynamic in a region that is in turmoil. And if you take just the Palestinian-Israeli situation, you have the potential to make peace with 57 nations—35 Muslim nations and 22 Arab nations. If the issue is resolved, they will recognize Israel.”

Even the relatively favored areas had rainfall of just 20 to 40 centimeters (8 to 15 inches)—where 20 centimeters (8 inches) is regarded as the absolute minimum to sustain agriculture—and the national average was less than 10 centimeters (4 inches)

Considering only “agricultural Syria,” the population is about five times as dense as Ohio or Belgium, but it does not have Ohio’s or Belgium’s other means of generating income.

Syria is not just a piece of land; it is densely populated. When I first visited Syria in 1946, the total population was less than 3 million. In 2010, it reached nearly 24 million.

The bottom line is that the population/resource ratio is out of balance. While there has been a marginal increase of agricultural land and more efficient cropping with better seed, neither has kept up with population growth.

During Ottoman rule the population was organized in two overlapping ways. First, there was no “Syria” in the sense of a nation-state, but rather provinces (Turkish: pashaliqs) that were centered on the ancient cities. The most important of these were Damascus, which may be the oldest permanently settled city in the world today, and Aleppo.

throughout its centuries of rule, the Ottoman Empire generally was content to have its subjects live by their own codes of behavior. It did not have the means or the incentive to intrude into their daily lives. Muslims, whether Turk or Arab or Kurd, shared with the imperial government Islamic mores and law. Other ethnic/religious “nations” (Turkish: millet) were self-governing except in military and foreign affairs.

the same groups also moved into mainly Muslim cities and towns, where they tended to live in more or less segregated neighborhoods that resembled medieval European urban ghettos or modern American “Little Italys” or “Chinatowns.”

Since this system was spelled out in the Quran and the Traditions (Hadiths) of the Prophet, respecting it was legally obligatory for Muslims. Consequently, when the Syrian state took shape, it inherited a rich, diverse, and tolerant social tradition.

the French created a “Greater” Lebanon from the former autonomous adjunct provinces (Turkish: sanjaqs) of Mount Lebanon and Beirut. To make it their anchor in an otherwise hostile Levant, they aimed both to make it Christian-dominated and big enough to exist as a state. But these aims were incompatible: the populations they added, taken from the pashaliq of Damascus, were mainly Muslim, so the French doomed Lebanon to be a precariously unbalanced society.

the French reversed course. They united the country as defined in the mandate but attempted to change its social and cultural orientation. Their new policy aimed to supplant the common language, Arabic, with French, to make French customs and law the exemplar, to promote Catholicism as a means to undercut Islam, and to favor the minorities as a means to control the Muslim majority. It was inevitable that the native reaction to these intrusions would be first the rise of xenophobia and then the spread of what gradually became a European style of nationalism.

When French policies did not work and nationalism began to offer an alternate vision of political life, the French colonial administration fell back on violence. Indeed throughout the French period—in contrast to the relatively laissez-faire rule of the Ottoman Empire—violence was never far below the outward face of French rule.

the “peace” the French achieved was little more than a sullen and frustrated quiescence; while they did not create dissension among the religious and ethnic communities, the French certainly magnified it and while they did not create hostility to foreigners, they gave the native population a target that fostered the growth of nationalism. These developments have lingered throughout the last 70 years and remain powerful forces today.

in the years after the French were forced out, coup leader after military dictator spoke in nationalist rhetoric but failed to lead his followers toward “the good life.”

for three and a half years, Syria became a part of the United Arab Republic.

Union did not work, so in 1961 Syrians were thrown back on their own resources. A fundamental problem they faced was what it meant to be a Syrian.

The more conservative, affluent, and Westernized nationalists believed that nationhood had to be built not on a religious but on a territorial base. That is, single-state nationalism (Arabic: wataniyah) was the focus of Syria’s statehood.

Their program, however, did not lead to success; its failure opened the way for a redefinition of nationalism as pan-Arab or folk nationalism (Arabic: qawmiyah). As it was codified by the Baath Party, it required that Syria be considered not a separate nation-state but a part of the whole Arab world and be domestically organized as a unified, secular, and at least partly Westernized state. This was a particularly difficult task because the dominant Muslim community, initially as a result of French rule and later as a result of domestic turbulence and foreign interference, regarded the members of the minority communities, particularly the Jewish community, as actual or potential turncoats.

as Syrians struggled for a sense of identity and came to suspect social difference and to fear the cooperation of minorities with foreigners, being an Alawi or a Christian or a Jew put people under a cloud. So, for Hafez al-Assad, the secular, nationalist Baath Party was a natural choice

Their answer was to try to bridge the gaps between rich and poor through a modified version of socialism, and between Muslims and minorities through a modified concept of Islam. Islam, in their view, needed to be considered politically not as a religion but as a manifestation of the Arab nation. Thus, the society they wished to create, they proclaimed, should be modern (with, among other things, equality for women), secular (with faith relegated to personal affairs), and defined by a culture of “Arabism” overriding the traditional concepts of ethnicity.

The “Resurrection” (Arabic: Baath) Party had its origins, like the nationalist-communist Vietnamese movement, in France. Two young Syrians, one a Christian and the other a Sunni Muslim, who were then studying in Paris were both attracted to the grandeur of France and appalled by the weakness of Syria. Like Ho Chi Minh, they wanted to both become like France and get the French out of their nation. Both believed that the future lay in unity and socialism. For Michel Aflaq and Salah Bitar, the forces to be defeated were “French oppression, Syrian backwardness, a political class unable to measure up to the challenge of the times,”

After Assad’s assault in 1982, the Syrian city of Hama looked like the Iraqi city of Fallujah after the American assault in 2004. Acres of the city were submerged under piles of rubble. But then, like Stalingrad after the German attack or Berlin after the Russian siege, reconstruction began. In a remarkable series of moves, Hafez al-Assad ordered the rubble cleared away, built new highways, constructed new schools and hospitals, opened new parks, and even, in a wholly unexpected conciliatory gesture, erected two huge new mosques. He thus made evident what had been his philosophy of government since he first took power: help the Syrian people to live better provided only that they not challenge his rule. In his thought and actions, his stern and often-brutal monopoly of power, he may be compared to the ruling men, families, parties, and establishments of Chinese, Iranian, Russian, Saudi Arabian, Vietnamese, and numerous other regimes.

Hafez al-Assad did not need to wait for leaks of documents: his intelligence services and international journalists turned up dozens of attempts by conservative, oil-rich Arab countries, the United States, and Israel to subvert his government. Most engaged in “dirty tricks,” propaganda, or infusions of money, but it was noteworthy that in the 1982 Hama uprising, more than 15,000 foreign-supplied machine guns were captured, along with prisoners including Jordanian- and CIA-trained paramilitary forces (much like the jihadists who appear so much in media accounts of 2013 Syria). And what he saw in Syria was confirmed by what he learned about Western regime-changing elsewhere.

As Iraq “imploded” in coups beginning in 1958 and morphed into Saddam Husain’s regime, the Syrians came to regard it as an enemy second only to Israel.

During the rule of the two Assads, Syria made considerable progress. By the eve of the civil war, Syrians enjoyed an income (GDP) of about $5,000 per capita. That was nearly the same as Jordan’s, roughly double the income per capita of Pakistan and Yemen, and five times the income of Afghanistan, but it is only a third that of Lebanon, Turkey, or Iran

In 2010, savaged by the great drought, GDP per capita had fallen to about $2,900, according to UN data. Before the civil war—and except in 2008 at the bottom of the drought, when it was zero—Syria’s growth rate hovered around 2 percent,

In social affairs, nearly 90 percent of Syrian children attended primary or secondary schools and between eight and nine in 10 Syrians had achieved literacy. On these measures, Syria was comparable to Iran, Saudi Arabia, and Libya despite having far fewer resources to employ.

Like his father, Bashar sought to legitimize his regime through elections, but apparently he never intended, and certainly did not find, a way satisfactory (to the public) and acceptable (to his regime) of enlarged political participation.

The lack of political participation, fear of public demands, and severe police measures made the regime appear to be a tyranny

This and its hostility to Israel led to large-scale, if covert, attempts at regime change by outside powers including the United States. These acts of subversion became particularly pronounced during the second Bush administration.

between 2 and 3 million of Syria’s 10 million rural inhabitants were reduced to “extreme poverty.”  

Four years of devastating drought beginning in 2006 caused at least 800,000 farmers to lose their entire livelihood and about 200,000 simply abandoned their lands, according to the Center for Climate & Security. In some areas, all agriculture ceased. In others, crop failures reached 75 percent. And generally as much as 85 percent of livestock died of thirst or hunger. Hundreds of thousands of Syria’s farmers gave up, abandoned their farms, and fled to the cities and towns

Syria was already a refuge for a quarter of a million Palestinians and about 100,000 Iraqis who had fled the war and occupation. Formerly prosperous farmers were lucky to get jobs as hawkers or street sweepers. And in the desperation of the times, hostilities erupted among groups that were competing just to survive.

And so tens of thousands of frightened, angry, hungry, and impoverished former farmers were jammed into Syria’s towns and cities, where they constituted tinder ready to catch fire.

Instead of meeting with the protesters and at least hearing their complaints, the government saw them as subversives. The lesson of Hama must have been at the front of the mind of every member of the Assad regime. Failure to act decisively, Hama had shown, inevitably led to insurrection. Compromise could come only after order was assured. So Bashar followed the lead of his father. He ordered a crackdown. And the army, long frustrated by inaction and humiliated by its successive defeats in confrontation with Israel, responded violently. Its action backfired. Riots broke out all over the country. As they did, the government attempted to quell them with military force. It failed. So, during the next two years, what had begun as a food and water issue gradually turned into a political and religious cause.

we don’t know much about the rebels. Hundreds of groups and factions—called “brigades” even when they are just a dozen or so people—have been identified. Some observes believe that there are actually over 1,000 brigades. A reasonable guess is that, including both part-time and full-time insurgents, they number about 100,000 fighters.

In Syria, quite different causes of splits among the brigades are evident. To understand the insurgency there, we must look carefully at the causes. The basis is religion

During the course of the Assad regime, the interpretation of Islam was undergoing a profound change. This was true not only of Syria but also of understanding, practice, and action in many other areas of the world.

tens of thousands of young foreigners flocked to Syria to fight for what they see as a religious obligation (Arabic: fi sabili’llah).

in Syria, while many Muslims found the Assad regime acceptable and many even joined its senior ranks, others saw its Alawi and Christian affiliations, and even its secularism and openness to Muslim participation, insupportable.

The foreign jihadists, like the more recent nationalists, put their emphasis on a larger-than-Syria range. For them, it is a folk nationalism not only to the Arab world but also to the wider world of Islam, affecting a billion people across the globe. What they seek is a restored Islamic world, a Dar ul-Islam, or a new caliphate.

the aims of the two broad groups—the Syrians and the foreigners—have grown apart in a way similar to the split that occurred in Arab nationalism. The Syrians focus on Syria and seek the overthrow of the Assad regime much as their fathers and grandfathers focused on the task of getting the French out of their country—their watan. Their nationalism is single-country oriented

all the rebels regard the conflict in Syria as fundamentally a religious issue. Particularly for the native rebels, as I have pointed out, the religious issue is overlaid by ethnic complexities.

It would be a mistake to regard the Syrian war, as some outside observers have done, as a fight between the forces of freedom and tyranny. If the opponents of the regime are fighting for some form of democracy, they have yet to make their voices heard.

as in Afghanistan, they have fought one another over territory, access to arms, leadership, and division of spoils as bitterly as they have fought their proclaimed enemy. This fracturing has made them impossible to defeat—as the Russians experienced in Afghanistan—but also, so far at least, incapable of governing on a national scale. But they are moving in that direction.

All observers agree that the foreign-controlled and foreign-constituted insurgent groups are the most coherent, organized, and effective. This is little short of astonishing as they share no common language and come from a wide variety of cultures.

Paradoxically, governments that would have imprisoned the same activists in their own countries have poured money, arms, and other forms of aid into their coffers. The list is long and surprising in its makeup: it includes Turkey; the conservative Arab states, particularly Qatar and Saudi Arabia; the EU member states; and the U.S.

The United States has a long history of covertly aiding insurgents in Syria, and has engaged in propaganda, espionage, and various sorts of dirty tricks. The rebels, naturally, have regarded the aid they’ve received as insufficient, while the government has regarded it as a virtual act of war. Both are right: it has not been on a scale that has enabled the rebels to win, but it is a form of action that, had another country engaged in it, seeking to overthrow the government, any American or European administration would have regarded as an act of war under international law.

Such covert intervention, and indeed overt intervention, is being justified on two grounds, the first being that the Syrian government is a tyranny. By Western standards, it is undoubtedly an authoritarian regime

However, the standards Western nations proclaim have been applied in a highly selective way. The EU and the U.S. enjoy cordial and mutually beneficial relations with dozens of tyrannical governments including most of the countries now attempting to regime-change Syria.              

Senior rebels have publicly threatened to carry out a genocide of the country’s main ethnic/religious minority, the Alawis. Scenes being enacted in Syria today recall the massacres and tortures of the wars of religion in 16th- and 17th-century Europe.

Most urgent in the minds of the EU and the U.S. is the second justification for intervention: the Syrian government is charged with using illegal chemical weapons. This is a very serious charge. However, doubts remain about who actually used the weapons. And, more importantly, even though the weapons are indeed horrible and are now generally considered illegal, several other states (the U.S., Israel, Egypt, and Iraq) have used them. Terrible as they are, they are only a small part of the Syrian problem—more than 99 percent of the casualties and all of the property damage in the war have been the result of conventional weapons. Getting rid of chemical weapons will neither in and of itself stop the war nor create conditions favorable to a settlement.

the cost of the war has been immense. And, of course, it is not over. We have only guesses on the total so far. One estimate is that the war has cost Syria upwards of $150 billion. Whole cities now resemble Stalingrad or Berlin in World War II. More than 2 million people have fled abroad while more than 4 million are internal refugees, remaining in Syria.

Lebanon. Even though there is little fighting there, the conflict in Syria is estimated to have cost that little country about $7.5 billion and doubled unemployment to 20 percent. About 1 million Lebanese were already judged by the World Bank as “poor,” and an additional 170,000 are now thought to have been pushed into poverty. The Syrian refugee population in the country has reached at least 1 million, making Syrians now almost a third of the total Lebanese population.

In Jordan, the story is similar. Half a million refugees are camped out there. One refugee encampment in the country houses over 100,000 people and has become Jordan’s fifth-largest city

However reprehensible the Syrian government may be in terms of democracy, it has not only given refugees and minorities protection but also maintained the part of Syria that it controls as a secular and religiously ecumenical state.

Tragic as these numbers are—the worst for nearly a century—factored into them is that Syria has lost the most precious assets of poor countries: most of the doctors and other professionals who had been painstakingly and expensively educated during the last century

Even more “costly” are the psychological traumas: a whole generation of Syrians have been subjected to either or both the loss of their homes and their trust in fellow human beings. Others will eventually suffer from the memory of what they, themselves, have done during the fighting. Comparisons are trivial and probably meaningless, but what has been enacted—is being enacted—in Syria resembles the horror of the Japanese butchery of Nanjing in World War II and the massacres in the 1994 Hutu-Tutsi conflict in Rwanda.

How the victims and the perpetrators can be returned to a “normal life” will be the lingering but urgent question of coming generations in Syria and elsewhere.

one in four or five people in the world today are Muslim: roughly 1.4 billion men, women, and children. That whole portion of the world’s population has its eyes on Syria. What happens there is likely to have a ripple effect across Asia and Africa. Thus, even though it is a small and poor country, Syria is in a sense a focal point of world affairs.

Unlike the Iraq and Afghan wars, the Syrian conflict will also have a “blowback” effect on the countries from which the Muslim fundamentalist insurgents come. It is in recognition of this fact that Russian President Vladimir Putin decided to intervene in the Syrian war.

Even if fighting dies down, “lasting and bitter war,” like the wars in Iraq and Afghanistan—regardless of what American and European politicians say or even hope—will necessarily involve “boots on the ground.” That is, it will be fought with guerrilla and terrorist tactics on the rebel side against the now-typical counterinsurgency methods on the other side.

Both groups of scientists found that West Antarctic glaciers had retreated far enough to set off an inherent instability in the ice sheet, one that experts have feared for decades.

Those six glaciers alone could cause the ocean to rise four feet as they disappear, Dr. Rignot said, possibly within a couple of centuries. He added that their disappearance will most likely destabilize other sectors of the ice sheet, so the ultimate rise could be triple that.

The new finding appears to be the fulfillment of a prediction made in 1978 by an eminent glaciologist, John H. Mercer of the Ohio State University. He outlined the vulnerable nature of the West Antarctic ice sheet and warned that the rapid human-driven release of greenhouse gases posed “a threat of disaster.” He was assailed at the time, but in recent years, scientists have been watching with growing concern as events have unfolded in much the way Dr. Mercer predicted

News media interest was enormous, in part because of Francis’ global popularity, but also because of the intriguing coalition he is proposing between faith and science.

Catholic bishops and priests around the world are expected to discuss the encyclical in services on Sunday. But Francis is also reaching for a wider audience, asking in the document “to address every person living on this planet.”

Advocates of policies to combat climate change have said they hoped that Francis could lend a “moral dimension” to the debate.

“Within the scientific community, there is almost a code of honor that you will never transgress the red line between pure analysis and moral issues,” said Hans Joachim Schellnhuber, founder and chairman of the Potsdam Institute for Climate Impact Research. “But we are now in a situation where we have to think about the consequences of our insight for society.”

Catholic theologians say the overarching theme of the encyclical is “integral ecology,” which links care for the environment with a notion already well developed in Catholic teaching: that economic development, to be morally good and just, must take into account people’s need for things like freedom, education and meaningful work.

“The basic idea is, in order to love God, you have to love your fellow human beings, and you have to love and care for the rest of creation,” said Vincent Miller, who holds a chair in Catholic theology and culture at the University of Dayton, a Catholic college in Ohio. “It gives Francis a very traditional basis to argue for the inclusion of environmental concern at the center of Christian faith.”

“Critics will say the church can’t teach policy, the church can’t teach politics. And Francis is saying, ‘No, these things are at the core of the church’s teaching.’ ”

in a passage certain to rankle some Christians, he chastises those who cite Genesis as evidence that man has “dominion” over the earth that justifies practices like mountaintop mining or fishing with gill nets.

“This is not a correct interpretation of the Bible as understood by the Church,” Francis writes. The Bible teaches human beings to “till and keep” the garden of the world, he says. “ ‘Tilling’ refers to cultivating, plowing or working, while ‘keeping’ means caring, protecting, overseeing and preserving.

His most stinging rebuke is a broad critique of profit-seeking and the undue influence of technology on society. He praises achievements in medicine, science and engineering, but says that “our immense technological development has not been accompanied by a development in human responsibility, values and conscience.”

The pope rejects the belief that technology and “current economics” will solve environmental problems, or “that the problems of global hunger and poverty will be resolved simply by market growth.”

Francis sharply criticizes the trading of carbon credits — a market-based system central to the European Union’s climate policy — and says it “may simply become a ploy which permits maintaining the excessive consumption of some countries and sectors.”

“All is not lost,” he writes. “Human beings, while capable of the worst, are also capable of rising above themselves, choosing again what is good, and making a new start.”

But regardless of industry, the families investing the most in presidential politics overwhelmingly lean right, contributing tens of millions of dollars to support Republican candidates who have pledged to pare regulations; cut taxes on income, capital gains and inheritances; and shrink entitlement programs.

In marshaling their financial resources chiefly behind Republican candidates, the donors are also serving as a kind of financial check on demographic forces that have been nudging the electorate toward support for the Democratic Party and its economic policies. Two-thirds of Americans support higher taxes on those earning $1 million or more a year, according to a June New York Times/CBS News poll, while six in 10 favor more government intervention to reduce the gap between the rich and the poor. According to the Pew Research Center, nearly seven in 10 favor preserving Social Security and Medicare benefits as they are.

The donor families’ wealth reflects, in part, the vast growth of the financial-services sector and the boom in oil and gas, which have helped transform the American economy in recent decades. They are also the beneficiaries of political and economic forces that are driving widening inequality: As the share of national wealth and income going to the middle class has shrunk, these families are among those whose share has grown.

Most of the families are clustered around just nine cities. Many are neighbors, living near one another in neighborhoods like Bel Air and Brentwood in Los Angeles; River Oaks, a Houston community popular with energy executives; or Indian Creek Village, a private island near Miami that has a private security force and just 35 homes lining an 18-hole golf course.

More than 50 members of these families have made the Forbes 400 list of the country’s top billionaires, marking a scale of wealth against which even a million-dollar political contribution can seem relatively small. The Chicago hedge fund billionaire Kenneth C. Griffin, for example, earns about $68.5 million a month after taxes, according to court filings made by his wife in their divorce. He has given a total of $300,000 to groups backing Republican presidential candidates. That is a huge sum on its face, yet is the equivalent of only $21.17 for a typical American household, according to Congressional Budget Office data on after-tax income.

“The campaign finance system is now a countervailing force to the way the actual voters of the country are evolving and the policies they want,” said Ruy Teixeira, a political and demographic expert at the left-leaning Center for American Progress.

The accumulation of wealth has been particularly rapid at the elite levels of Wall Street, where financiers who once managed other people’s capital now, increasingly, own it themselves. Since 1979, according to one study, the one-tenth of 1 percent of American taxpayers who work in finance have roughly quintupled their share of the country’s income. Sixty-four of the families made their wealth in finance, the largest single faction among the super-donors of 2016.

instead of working their way up to the executive suite at Goldman Sachs or Exxon, most of these donors set out on their own, establishing privately held firms controlled individually or with partners. In finance, they started hedge funds, or formed private equity and venture capital firms, benefiting from favorable tax treatment of debt and capital gains, and more recently from a rising stock market and low interest rates

In energy, some were latter-day wildcatters, early to capitalize on the new drilling technologies and high energy prices that made it economical to exploit shale formations in North Dakota, Ohio, Pennsylvania and Texas. Others made fortunes supplying those wildcatters with pipelines, trucks and equipment for “fracking.”

The families who give do so, to some extent, because of personal, regional and professional ties to the candidates. Jeb Bush’s father made money in the oil business, while Mr. Bush himself earned millions of dollars on Wall Street. Some of the candidates most popular among ultrawealthy donors have also served in elected office in Florida and Texas, two states that are home to many of the affluent families on the list.

the giving, more broadly, reflects the political stakes this year for the families and businesses that have moved most aggressively to take advantage of Citizens United, particularly in the energy and finance industries.

The Obama administration, Democrats in Congress and even Mr. Bush have argued for tax and regulatory shifts that could subject many venture capital and private equity firms to higher levels of corporate or investment taxation. Hedge funds, which historically were lightly regulated, are bound by new rules with the Dodd-Frank regulations, which several Republican candidates have pledged to roll back and which Mrs. Clinton has pledged to defend.

And while the shale boom has generated new fortunes, it has also produced a glut of oil that is now driving down prices. Most in the industry favor lifting the 40-year-old ban on exporting oi

Democracy depends on accountability, and accountability depends on knowledge. The Torture Committee report is potentially an enormous step forward.

Schlissel, a former provost at Brown University and a scientist, expressed concern to a faculty group recently that Michigan, annually ranked among the top-rated public universities in the nation and owners of the most victories in college football history, had admitted football players who were not as academically qualified as the rest of the student body.

Michigan fans do not readily welcome change. They even have a name for one of their own: a Michigan Man.

When Gee was president at Ohio State, he was asked if he would fire the football coach Jim Tressel, who had come under fire for an N.C.A.A. investigation into violations involving his players. “I’m just hoping that the coach doesn’t dismiss me,” he said, a line that landed him in hot water.

Schlissel, who apologized to Hoke for his remarks to the faculty group, declined to comment on his concerns or his future plans. Schlissel is trusting Hackett to decide Hoke’s fate, but he will surely play a role in deciding the future of Wolverines football.

“I’m amazed that the regents would hire a president with so little grounding in intercollegiate athletics, so little understanding of it,” Bay said. “I have sympathy for the man, that he’s been put in a position where he has to deal with a major part of the university and has no experience. He’s never been in a culture like this.”

“If this university can’t get this right,” Bernstein, the regent, said, “then no university can.”

the most shareable moments come when a story lights up the deepest recesses of our minds

“Hate, fear of the other, anger — they come directly from the nonconscious, and that’s why they’re so easy to evoke,”

news stories were more likely to be shared if they elicited emotions like awe, anger and anxiety.

as long as stories about Mr. Trump are receiving as many eyeballs as possible, it doesn’t really matter if people are reacting negatively to him. In fact, it probably helps his popularity.

That Mr. Trump is both volatile in nature and allergic to nuance is part of his viral success. Humans use mental shortcuts to process information quickly while conserving brain power. This means that we often don’t think critically about the information we’re receiving before sharing it with others.

Unsurprisingly, that can mean that things that are not true go viral. But lies, like fear, can maintain a powerful grasp on the human mind.

“Once we see something and accept it as true, it’s really, really hard to falsify the belief,” said Rosanna Guadagno, a social psychologist at the University of Texas at Dallas. “I’ve occasionally spread something that turned out to be false, and the sad thing is, I’m still trying to scrub that out of my memory as something I’ve accepted as real.”

According to Bradley M. Okdie, a social psychologist at Ohio State University at Newark, conservatives are more likely to share a given piece of content than liberals are, especially if it provokes a negative emotion.

“Conservatives tend to be a lot more reactive to negative information and they also tend to be a lot more insular in nature, and they also tend to have less tolerance for ambiguity,” Professor Okdie said. “Conservatives would prefer a negative concrete statement to a slightly positive, uncertain statement.”

With his us vs. them invective and his refusal to denounce hate-filled speech from some of his supporters, Mr. Trump is an echo chamber for certain corners of the far righ

But Kik says it can find users on its system with only a user name. And because Kik is based in Canada, law enforcement officials say, it can be a slow process. Requests have to go through the United States Justice Department.

when it comes to the content of conversations, they don’t retain information including photos and videos. So it makes it tough for us.”

Law enforcement officials say they often run across Kik in cases of “sextortion,” or blackmail, in which a sexual predator coaxes a young person to send nude photos — and then threatens to post the photos online, or alert the child’s parents or harm the child, if he or she does not send more.

Professor Finkelhor cautions against “technophobia,” saying character traits — not technology — make young people vulnerable. Those who are socially isolated, who have conflict with their parents, who are bullied in school or who are depressed are “at higher risk,” he said, “both in face-to-face and electronic environments.”

Investigators learned only later that the girl had met Mr. Schroeder on Kik. Asked about the odds of finding her if the man had not gone onto Facebook, Mr. Frattare, of the Ohio crime task force, said, “In my opinion, it would have been slim to none.

Mr Trump's lead in New Hampshire is the first time the New York businessman - who has never held political office - has translated his widespread support in opinion polls into an election victory.

On Tuesday Ohio Governor John Kasich came second in the Republican vote, with former Florida Governor Jeb Bush, Texas Senator Ted Cruz and Florida Senator Marco Rubio all vying for third place.

"he wants to give away our country, folks!"

With close to 90% of the votes counted, Senator Sanders has a lead of more than 20 percentage points over Mrs Clinton in the two-horse race for the Democratic nomination.

"What the people here have said is that given the enormous crises facing our country, it is just too late for the same old, same old establishment politics and establishment economics," Mr Sanders told cheering supporters.

Francis' comments came hours after he concluded a visit to Mexico, where he prayed at the border for people who died trying to reach the U.S. While speaking to reporters on the papal plane, he was asked what he thought of Trump's campaign pledge to build a wall along the entire length of the border and expel millions of people in the U.S. illegally.

"A person who thinks only about building walls, wherever they may be, and not building bridges, is not Christian," he said. While Francis said he would "give the benefit of the doubt" because he had not heard Trump's border plans independently, he added, "I say only that this man is not a Christian if he has said things like that."

Trump, a Presbyterian and the front-runner for the Republican presidential nomination, responded within minutes. "For a religious leader to question a person's faith is disgraceful," he said at a campaign stop in South Carolina, which holds a key primary on Saturday. "I am proud to be a Christian, and as president I will not allow Christianity to be consistently attacked and weakened."

Trump also raised the prospect of the Islamic State extremist group attacking the Vatican, saying that if that happened, "the pope would have only wished and prayed that Donald Trump would have been president because this would not have happened."

Francis, the first pope from Latin America, urged Congress during his visit to Washington last year to respond to immigrants "in a way which is always humane, just and fraternal." He irked Republicans on the same trip with his forceful call for international action to address climate change.

Immigration is among the most contentious issues in American politics. Republicans have moved toward hardline positions that emphasize law enforcement and border security, blocking comprehensive legislation in 2013 that would have included a path to citizenship for many of the 11 million people in the U.S. illegally.

Hispanics, an increasingly large voting bloc in U.S. presidential elections, have flocked to Democrats in recent years. President Barack Obama won more than 70 percent in the 2012 election, leading some Republican leaders to conclude the party must increase its appeal to them.

However, the current GOP presidential primary has been dominated by increasingly tough rhetoric. Trump has insisted that Mexico will pay for his proposed border wall and has said some Mexicans entering the U.S. illegally are murderers and rapists.

While Trump's words have been among the most inflammatory, some of his rivals have staked out similar enforcement positions. Texas Sen. Ted Cruz and retired neurosurgeon Ben Carson are among those who have explicitly called for construction of a wall.

Former Florida Gov. Jeb Bush, one of the few GOP candidates proposing a path to legal status for people already in the U.S. illegally, said Thursday he supports "walls and fencing where it's appropriate." Bush said that while he gets his guidance "as a Catholic" from the pope, he doesn't take his cues from Francis on "economic or environmental policy."

Marco Rubio, another Catholic seeking the GOP nomination, said that Vatican City has a right to control its borders and so does the United States. Rubio said he has "tremendous respect and admiration" for the pope, but he added, "There's no nation on Earth that's more compassionate on immigration than we are."

Cruz said he was steering clear of the dispute. "That's between Donald and the pope," he said. "I'm not going to get in the middle of them." Ohio Gov. John Kasich, on the other hand, said he was staunchly "pro-Pope."

The long-distance exchange between the pope and Trump came two days before the voting in South Carolina, a state where 78 percent of adults identify as Christian, according to the Pew Research Center's 2014 U.S. Religious Landscape Study. Of that group, 35 percent identify as evangelical and 10 percent as Catholic, the survey found.

It's unclear what impact, if any, the pope's rhetoric will have, here or in other states. An October poll conducted by The Associated Press-NORC Center for Public Affairs Research found that most Americans had no strong opinion on the pope's approach to immigration issues, though he was overall viewed favorably.

That same year, Britain's left-leaning Guardian newspaper ran a public campaign targeting a critical county in Ohio with a letter-writing blitz, urging people there to vote for John Kerry.

It was a bid to give foreigners a say in the US presidential election. Clark County was a swing district in a swing state; in 2000 Al Gore won the area by a narrow margin.

In 2008 of course the world rallied firmly behind Barack Obama. Two hundred thousand people turned out to see the candidate in Berlin before the election. Italian trattorias started a roaring trade in Obama pizzas, a curious, un-Italian mix of ham and pineapple toppings.

So, what does the world make of Donald Trump? Mr Trump has some admirers in Europe. A few on the extreme end of the political spectrum like his tough line on immigration. Jean-Marie Le Pen, the founder of the French National Front, said if he were American he'd vote Trump.

What really matters is whether the 6-10% of voters in the middle of the American political spectrum, the people who actually decide elections here, are swayed by global opinion. And they may be, for two reasons.

middle-class and working-class people have been neglected by the existing political establishment,

There are echoes of Trumpism in the nationalist parties of Britain, Denmark, Netherlands, Greece as well as France.

Here's a sample of the public disapproval. Germany's Der Spiegel has called Trump the most dangerous man in the world. Britain's David Cameron says his plan to ban Muslims is divisive and unhelpful.

The French liberal newspaper Liberation has described him as a nightmare turned reality. JK Rowling tweeted that he's worse than Voldemort

Will the international reaction make a shred of difference to Trump's chances of getting nominated and then elected? 2004 would suggest not.

But the voices of support are drowned out by almost universal condemnation. When it comes to Trump, Europe is apoplectic. Fascinated, but appalled.

Invoking global opinion in the context of US elections is a fool's errand. Perfectly understandably, voters in Paris, Pennsylvania, really don't give a damn what voters in Paris, France, think about their political choices. And why should they?

At the time, a local newspaper editor told the BBC that it was the well-publicised letter campaign that lost it for the Democrats. It will go down in history as one of the biggest fiascos in foreign meddling.

Imagine if your much-respected but slightly annoying older sibling (the US) came home with a fantastically unsuitable date (Trump). Part of you is titillated but part of you is appalled, thinking, "Oh my God, this could go horribly wrong." After Super Tuesday, Europe is fast moving from the former to the latter.

Although America still feels under siege from Islamic extremism, American troops are not being killed in large numbers in Iraq and Afghanistan. Supporting Bush was in some ways a proxy for supporting those soldiers.

It's hard to know at this stage what impact foreign opinion will have in this race, but it's fairly clear the world is not going to suddenly fall in love with the man Republicans are rapidly choosing to be their candidate for the White House.

Stanley B. Greenberg, whose research in Macomb County in the 1980s popularized the term “Reagan Democrat,” said Mr. Trump might put the Rust Belt into play. “There’s no doubt there’s new voters coming into the Republican primary process,” he said.But Mr. Greenberg added that there was an equal potential for a backlash in an electorate that is more racially and culturally diverse. “The country’s changed pretty dramatically from the time when Reagan Democrats were calling the shots,” he said.

Detroit’s automakers are experiencing record sales.Nonetheless, the narrative of decline is pervasive, especially because many of the new jobs being created pay far less.“We’ve got McDonald’s and Burger King jobs, and that’s about it,” said Mr. Reidt, the fire captain.

“I think what it represents is Republicans coalescing, saying it would be a disaster for Donald Trump to be our nominee and we’re going to stand behind the strongest conservative in the race,” Mr. Cruz told reporters in Coeur d’Alene, Idaho, one of four states with Republican contests on Tuesday.

Mr. Trump’s losses underlined his continued vulnerability in states that hold time-intensive caucuses: He has lost five of seven such contests. He has performed far better in states holding primaries, which require less organization, and some of which also allow Democrats and independents to vote in Republican races.

The results suggested that a substantial number of Republicans were still uneasy about Mr. Trump: He finished above 40 percent in just one state. It was an indication that the growing campaign to deny Mr. Trump the nomination may not be a pointless exercise. The Stop Trump campaign was joined last week by Mitt Romney, who delivered a blistering attack on the Republican front-runner, portraying him as a threat to the party and the nation. And Mr. Trump reinforced questions about his candidacy at a debate on Thursday by making a barely veiled reference to his penis.

Whether he has incurred significant damage will be better known on Tuesday, if Mr. Kasich and Mr. Cruz can compete in Michigan and Mr. Cruz can threaten him in Mississippi.

Mr. Trump’s comments about building a wall along the border with Mexico and about illegal immigrants causing crime have drawn demonstrations almost everywhere he goes, and that was true in Wichita, too. Trump supporters in the caucus line engaged in shouting with several dozen protesters, many of them Hispanics, who make up 20 percent of the city’s population. Trucks with Mexican flags hanging out the windows and Latin music blaring from the speakers cruised slowly past the line.
