while stressing that the U.S.’s ultimate goal was complete denuclearization by North Korea, subject to stringent verification.

If high-level talks get under way, a key question will be what North Korea and the U.S. mean when they talk about “denuclearization.” The underlying assumption of American policy has long been that it means a North Korea without any nuclear weapons or a nuclear-weapons program.

The North may define denuclearization as a long-term goal that would only be achieved after the U.S. withdraws troops from South Korea and effectively ends the U.S.-South Korean military alliance.

“North Korean regimes have repeatedly used talks and empty promises to extract concessions and buy time,” he said. “We’ve got to break this cycle.”

“If the talks between the two leaders do not go well, it is not an excuse to justify military action for a situation that has no military solution.”

They said Mr. Kim had confirmed that he was prepared to suspend nuclear weapons and missile tests and agreed to discuss eliminating his nation’s nuclear arsenal. They also said Mr. Kim wouldn’t object to U.S.-South Korean military maneuvers, scheduled to take place next month in the region.

In a September appearance at the U.N., Mr. Trump said the U.S. would “totally destroy North Korea” if attacked and vowed that Mr. Kim would not survive the devastations. “Rocket man is on a suicide mission for himself,” Mr. Trump said.

by his lack of direct contact with foreign leaders, and his apparent unwillingness to stray too far from Pyongyang. Compared with his father, Kim Jong Il, the current dictator had little lead time before taking the reins.

“Previous Chinese negotiating behavior suggests that a meeting with Xi carries real weight

Mr. Kim and his wife met Mr. Xi and his wife during a lunch that “was overflowing with a harmonious and intimate atmosphere from its beginning to the end,”

The visit also allowed Beijing, with whom relations had soured, to play a central role in efforts to find a solution to the nuclear standoff.

Mr. Kim’s willingness to bring his wife to dinners with the South Korean envoys and with the Chinese president helps to make him “look like a fuller leader—a three-dimensional person, not this caricature,” she said.

which North Korean state media said was accepted “with pleasure”—though Chinese state media didn’t mention the invitation, one of several differences that hinted at enduring tensions between the neighbors.

In talks with the U.S., security analysts expect Mr. Kim to seek recognition as a nuclear-weapons state, or to demand sanctions relief and U.S. security guarantees in return for giving up its nuclear arms.

North Korean leaders’ preferred means of travel—armored train—would appear to reduce the likelihood of a summit in Scandinavia or Switzerland, given the distance and security concerns. Mr. Kim’s trip, like that of his father, w

But in venturing beyond his borders for the first time since taking power, Mr. Kim has signaled he can rub shoulders with world leaders like Mr. Xi.

Kim is sending a signal that he has options outside of full capitulation to Trump.”

Still, other drivers said the job wasn’t overly difficult. “It’s about being alert, if you can’t be alert for a few straight hours then you’re not a very good driver,” a former Waymo test operator said. Video taken from inside the Uber vehicle, released by Tempe police, appears to show the vehicle heading straight into the pedestrian without slo

It is the second time in a year that Uber has ​temporarily halted testing following an accident involving one of its autonomous cars.

Uber began making the transition to using single test operators nearly three years after embarking on self-driving vehicle development. General Motors Co.’s Cruise Automation self-driving unit, which was founded in 2013, still has two test drivers in every car. Waymo—which has logged more than five million testing miles, by far the most of any company—began using one safety operator in many of its cars in 2015, about six years after its program began. Waymo now runs most vehicles without humans behind the wheel in the Phoenix area and plans to launch a commercial robot service later this year.

Urdu is the national language of Pakistan but for all practical purposes, English is treated as an official language - most government ministries use English and it is also spoken by the country's elite.

Several political parties and literary bodies carried out a protest on 22 February - International Mother Language Day - urging the Pakistan government to declare all major languages of the country as "national languages".

caught up in the formidable political divide that has undermined previous attempts to tighten rules for firearms.

President Trump, who plans to meet with leaders of the video game industry Thursday, has not put forward his own school safety proposal, after initially saying he supported arming teachers, raising the age for some gun purchases and even removing guns from people deemed dangerous before a judicial review.

In addition to the waiting period and an increase in the minimum age, the bill also would ban the possession or sale of bump stocks, which allow semiautomatic rifles to fire more rapidly.

A federal prosecutor said the incidents constituted attempted murder, and said it was good fortune that no one died in the attacks.

Germany was shocked by a wave of attacks on refugee homes, angry protests and open xenophobia

Largely focused in the former communist east where disenchantment spilled over into fury at the government which, so the argument goes, opened its arms to refugees but left its own behin

Today's verdict forces Germany to, once again, examine uncomfortable truths. The migrant crisis destroyed old taboos; what was considered unspeakable just a few years ago is now openly discussed (even in the Bundestag where the far right Alternative for Germany (AfD) is now the largest opposition party). Few, of course, condone this level of violence but a small - growing - number of Germans now support the sentiment behind it.

In his closing statements, Senior Prosecutor Jörn Hausschild said he was convinced the group's crimes were based on xenophobic, right-wing extremist and Nazi ideology.

Germany has seen a rise in anti-Islam, far-right activity in recent years coinciding with the country's acceptance of more than one million migrants and refugees since 2014.

The Alternative for Germany (AfD) far-right political party won its first parliamentary seats in last year's election - becoming the third largest party with 12.6% of the vote.

Neighbouring Belgium has a gap of just 2.5% whereas for women in Lithuania, it is a staggering 24.2%.

The West, particularly France, considers Burkina Faso a key ally in the fight against al Qaeda in the region.

Its members "expressed their solidarity with Burkina Faso in its fight against terrorism and stressed the need to intensify regional and international efforts to combat terrorism and violent extremism, which may be conducive to terrorism."

The country was formerly known as the Republic of Upper Volta when it was established in 1958 as a self-governing colony under France. It gained full independence in 1960.

France is also struggling to bring down its unemployment rate, which stands at roughly 10%.

France has relatively low income inequality and fewer of its citizens are at risk of poverty than in Germany or the U.K.

The percentage of GDP that the government spends on social programs and welfare is much higher in France than other major economies.

The generous welfare system has led to higher budget deficits, however, and the French healthcare system is in desperate need of more cash. The IMF has called for economic reforms to bring public spending under control.

Mr. Yun predicts sales will remain flat for all of 2018, due to inventory shortages and eroding affordability, as both prices and mortgage rates rise.

A homeowner with a median-priced home in the San Francisco area will receive $4,500 less in housing-related tax benefits in the first year of a 30-year mortgage this year, according to real-estate data company Apartment List. A homeowner in the same position in the New York metro area would receive $1,500 less annually.

Weakness at the high end is being driven by stock market volatility and the $10,000 cap the tax bill placed on deducting state and local property taxes

“People are being a little more cautious than they were before,” Mr. Glazer said. “Buyers have a number in mind, and they’re willing to stick their ground more than in the past.”

Kalena Masching, a Redfin agent in Silicon Valley, said she has seen a pickup in activity in recent weeks as buyers and sellers have digested the implications of the tax bill. Buyers are putting down larger down payments to bring the size of their mortgages below the new $750,000 cap. But that could be a challenge if the stock market continues to fluctuate, because buyers might want to hold on to more of their cash

s. Masching said she is also hearing more from older buyers who are thinking about selling their homes and using the proceeds to retire out of state, prompted in part by the changes to the tax law

“I’m hoping it’s going to be better. We never got any inventory last year,” said Ms. Masching. “The big concern for our sellers is: Where are they going to go?”

Rhian Daniel, a 50 year old who works for a medical startup, and his wife have been looking for a home for about four years, both in the Bay Area and further afield. The couple have largely given up for the moment, and are considering eventually moving to a place like Dallas, with lower home prices and property taxes.

Mr. Daniel’s wife is a therapist, and they both have student debt that limits the size of the mortgage they can get.

In January 2017, Mr. Obama’s administration launched a case at the WTO against China for subsidizing aluminum

Mr. Trump has failed to follow up. Last week, Mr. Trump invoked a little-used 1962 statute to promise tariffs of 25% on imported steel and 10% on aluminum, ostensibly for national security, a factor that led his chief economic adviser, Gary Cohn, to announce his resignation Tuesday.

Chinese forced technology transfer, commercial espionage and intellectual-property theft, all aimed at creating Chinese champions in key industries by 2025

Yet China exports little steel to the U.S. because of existing duties and accounts for just 11% of its aluminum imports, far behind Canada. The Commerce Department argued for a global remedy because Chinese production depresses global prices and drives foreign producers out of third markets, and they then ship to the U.S.

It noted that since 2003 China has four times promised to address overcapacity in steel production, as its actual capacity quadrupled to roughly half the world total. “The crisis confronting the U.S. aluminum industry is China, plain and simple,” one industry group told the department.

When the EU threatened to retaliate, Mr. Trump said he would escalate by raising duties on European cars.

This means the pain of Mr. Trump’s tariffs will fall not on China but on actors that play by the rules, including Canada, Japan and the European Union.

The U.S. is preparing a sweeping penalty against China, but it would be more effective if done jointly; otherwise, Beijing may simply persuade others to hand over their technology in exchange for Chinese sales or capital.

S., EU and Japan launched a joint WTO complaint against China for restricting exports of “rare earths,” which are vital to many advanced technologies.

In 2014, they won and China lifted its restrictions. One former U.S. trade official says the U.S. could create a similar united front against Chinese takeovers of technology companies: “That would get their attention.” Nor would it violate WTO rules, which are less restrictive on investment than tariffs, he said.

“We are much more likely to get our allies to work with us if we aren’t punishing them for selling us steel that our consumers want to buy.”

As the Syrian conflict began to encroach on a corner of the country spared early in the war, the teenager traveled to a training camp in Iraq’s remote Qandil Mountains. Soon Islamic State began seizing large parts of Syria, including some Kurdish areas, and she headed to the war’s front lines.

The Congressional Leadership Fund, the super PAC controlled by House Speaker Paul Ryan, offered mock congratulations to Laura Moser, the Bernie Sanders-aligned Democrat who advanced to a runoff for a Houston-area House seat held by Republican Rep. John Culberson. Ms. Moser had been attacked by the Democratic Congressional Campaign Committee.

In the Seventh District, the top fundraiser—nonprofit executive Alex Triantaphyllis—came in fourth. In a Dallas House Democratic primary, the best fundraiser by far was a former Hillary Clinton aide, Ed Meier, who placed behind candidates who hadn’t raised even half the amount he had. He had more than $300,000 on hand as of Feb. 14 but failed to make the runoff.

They won runoff positions in all three of the most closely watched and competitive House Democratic primaries.

Prince Mohammed, the kingdom’s de facto ruler, is pushing to end its dependence on oil revenues. That plan will largely depend on Saudi Arabia—a country with a Byzantine bureaucracy and an opaque legal system—becoming more attractive to foreign investors.

He is creating a new and vibrant Saudi Arabia,” said one of the billboards, sponsored by a Saudi consulting firm.

Billboards touting Prince Mohammed as the face of change in the kingdom could be seen in the streets of London.

But the two leaders, Prince Mohammed and Mrs. May, will also have to address difficult issues like the Saudi war in Yemen.

he added that “we are all concerned about the appalling humanitarian situation in Yemen,” but said that engaging with the Saudi leadership was the best way to get aid into the country.

Britain has deployed the monarchy as a tool of soft power with the Gulf’s Arab states before. Prince Charles has traveled frequently to Saudi Arabia—on one occasion even participating in the traditional Saudi sword dance.

But Prince Mohammed’s visit also underscores the stark differences between the two monarchies.
