Something similar might be said about “The Maniac,” Benjamín Labatut’s new novel, whose designated Prometheus is the Hungarian-born polymath John von Neumann, a pioneer of A.I. as well as an originator of game theory.

both narratives are grounded in fact, using the lives and ideas of real people as fodder for allegory and attempting to write a new mythology of the modern world.

on Neumann and Oppenheimer were close contemporaries, born a year apart to prosperous, assimilated Jewish families in Budapest and New York. Von Neumann, conversant in theoretical physics, mathematics and analytic philosophy, worked for Oppenheimer at Los Alamos during the Manhattan Project. He spent most of his career at the Institute for Advanced Study, where Oppenheimer served as director after the war.

More than most intellectual bastions, the institute is a house of theory. The Promethean mad scientists of the 19th century were creatures of the laboratory, tinkering away at their infernal machines and homemade monsters. Their 20th-century counterparts were more likely to be found at the chalkboard, scratching out our future in charts, equations and lines of code.

MANIAC. The name was an acronym for “Mathematical Analyzer, Numerical Integrator and Computer,” which doesn’t sound like much of a threat. But von Neumann saw no limit to its potential. “If you tell me precisely what it is a machine cannot do,” he declared, “then I can always make a machine which will do just that.” MANIAC didn’t just represent a powerful new kind of machine, but “a new type of life.”

More than 200 years after the Shelleys, Prometheus is having another moment, one closer in spirit to Mary’s terrifying ambivalence than to Percy’s fulsome gratitude. As technological optimism curdles in the face of cyber-capitalist villainy, climate disaster and what even some of its proponents warn is the existential threat of A.I., that ancient fire looks less like an ember of divine ingenuity than the start of a conflagration. Prometheus is what we call our capacity for self-destruction.

Oppenheimer wasn’t a principal author of that theory. Those scientists, among them Niels Bohr, Erwin Schrödinger and Werner Heisenberg, were characters in Labatut’s previous novel, “When We Cease to Understand the World.” That book provides harrowing illumination of a zone where scientific insight becomes indistinguishable from madness or, perhaps, divine inspiration. The basic truths of the new science seem to explode all common sense: A particle is also a wave; one thing can be in many places at once; “scientific method and its object could no longer be prised apart.”

. Oppenheimer’s designation as Prometheus is precise. He snatched a spark of quantum insight from those divinities and handed it to Harry S. Truman and the U.S. Army Air Forces.

Labatut’s account of von Neumann is, if anything, more unsettling than “Oppenheimer.” We had decades to get used to the specter of nuclear annihilation, and since the end of the Cold War it has been overshadowed by other terrors. A.I., on the other hand, seems newly sprung from science fiction, and especially terrifying because we can’t quite grasp what it will become.

Von Neumann, who died in 1957, did not teach machines to play Go. But when asked “what it would take for a computer, or some other mechanical entity, to begin to think and behave like a human being,” he replied that “it would have to play, like a child.”

the intellectual drama of “Oppenheimer” — as distinct from the dramas of his personal life and his political fate — is about how abstraction becomes reality. The atomic bomb may be, for the soldiers and politicians, a powerful strategic tool in war and diplomacy. For the scientists, it’s something else: a proof of concept, a concrete manifestation of quantum theory.

If Oppenheimer took hold of the sacred fire of atomic power, von Neumann’s theft was bolder and perhaps more insidious: He stole a piece of the human essence. He’s not only a modern Prometheus; he’s a second Frankenstein, creator of an all but human, potentially more than human monster.

“Technological power as such is always an ambivalent achievement,” Labatut’s von Neumann writes toward the end of his life, “and science is neutral all through, providing only means of control applicable to any purpose, and indifferent to all. It is not the particularly perverse destructiveness of one specific invention that creates danger. The danger is intrinsic. For progress there is no cure.”

He argues that the tools of social media are just too sharp for young minds. On digital platforms teens parade themselves, often to an audience of strangers, and this is leading to addiction, paranoia and despair

For girls, the effect is especially acute. ‘What we’re seeing is a very sharp, sudden change in girls’ mental health all around the Anglosphere and the Nordic countries,’ he says. A big change was evident from 2013, when physical friendship groups started to be supplanted by smartphones and online chat. ‘But you cannot grow up in networks. You have to grow up in communities.’

boys who have religion in their lives seem to be less susceptible. ‘If you’re a kid who’s a religious conservative, on average, your mental health is not really much worse than it was ten years ago

But if you’re a secular liberal girl, you’re probably more than twice as likely to have a mental health problem.’

a University of Michigan survey into ‘self-derogation’ – i.e., how likely teenagers are to say they are ‘no good’ or ‘can’t do anything right’. Figures had been stable for years but started rising sharply ten years ago – except for among boys who identified as conservative and said that religion was important to them.

irls simply use social media more. But Professor Haidt also thinks they are more likely to buy into what he calls the ‘three great untruths’ of social media

The first is that they are fragile and can be harmed by speech and words.

Next, that their emotions, and especially their anxieties, are reliable guides to reality.

And finally, that society is one big battle between victims and oppressors. All this, he says, is the subtext to social media discourse.

‘It’s what I’ve been calling the phone-based child,’

So we had playdates in childhood, up until around 2010.’ In Britain, he says, the number of children who went on real-life playdates then fell sharply.

Social media is a bit of a misnomer, he says. It’s no longer about connecting people, but ‘performing on a platform’. Perhaps this is fine for grown-ups, but not for children, ‘where they can say things in public, including to strangers, and then be publicly shamed by potentially millions of people

Children should not be on social networks. They should be playing in person. Social media platforms should never be accessed by children until they’re 18. It’s just insane that we let kids do these things.’

I ask if he thinks all platforms are equally dangerous

‘TikTok is probably the worst for their intellectual development. I think it literally reduces their ability to focus on anything while stuffing them with little bits of stuff that was selected by an algorithm for emotional arousal. Not for truth.’

if you get your news from social media (which many people do – in the UK, Instagram has overtaken all newspapers as a news source), this can change your view of the world, especially as the algorithms tend to promote the most provocative views.

If asked to choose whether they side more with Israel or Hamas, ‘the great majority of Americans side with Israel, except for Gen Z, which is split 50-50’,

‘There was a Twitter thread recently showing how if you look at what people are saying on TikTok, you can understand why

TikTok and Twitter are incredibly dangerous for our democracy. I’d say they’re incompatible with the kind of liberal democracy that we’ve developed over the last few hundred years.’

Might it just be the case, I ask, that there’s less of a stigma around mental health now, so teenagers are far more likely to admit that they have problems?

why is it, then, that right around 2013 all these girls suddenly start checking into psychiatric inpatient units? Or suicide – they’re making many more suicide attempts. The level of self-harm goes up by 200 or 300 per cent, especially for the younger girls aged ten to 14

we see very much the same curves, at the same time, for behaviour. Suicide, certainly, is not a self-report variable. This is real. This is the biggest mental health crisis in all of known history for kids.’

he increased number of suicides since 2010 is so large that I suspect this is among the largest public health threats to children since the major diseases were wiped out

In Britain, suicide rates started rising in 2014, up about 20 per cent for boys (to 420 a year) and 60 per cent for girls (to 160 a year).

What should parents do? They know that if they try to remove their teenager’s smartphone, their child will accuse them of destroying his or her social life. ‘That’s a perfect statement of what we call a collective action problem,’

‘Any one person doing the right thing is in big trouble. But why do we ever let our kids on social media? It’s only down to the dynamic you just said.’ New norms are needed, he says. And his book will suggest four.

Rule one, he says: no smartphones before the age of 14.

‘Give them a flip phone. Millennials had flip phones. They texted each other

Rule two: no social media before 16

His third rule: no phones in schools.

finally: more unsupervised play. ‘Both of our countries freaked out in the 1990s, locked up our kids because we lost trust in each other. We thought everyone was a child molester or a rapist.’ Children and teens could do with six or seven hours each day out of contact with their parents, he argues. Keeping them inside risks more harm than the outside world would pose.

On the Israeli side, blind U.S. security guarantees have not provided a path to peace. Instead, they have provided Israel with the reassurance that it can engage in increasingly destructive efforts, such as the expansion of illegal settlements in the West Bank, without any real consequences.

At the same time, Israel has become a global leader in weapons exports and boasts one of the most technologically sophisticated militaries in the world. All of these factors have created a sense among Israeli policymakers that they can indefinitely contain — physically and politically — the Palestinian question.

Nowhere is this more apparent than in the recent efforts, driven by the United States, first under the Trump administration and continuing under President Biden, to pursue normalization between Israel and the Arab world. While in many ways this normalization is long overdue, it has been premised on the notion that economic incentives — and a shared regional security interest in deterring malign Iranian influence — can integrate Israel, indefinite occupation and all, into the Arab world.

This premise has been shattered — likely intentionally on Hamas’s part — by the Gaza conflict and its rapid recentering of the Palestinian cause on a global stage.

As civilian deaths in Gaza and the West Bank continue to mount, it is clear any sort of Saudi normalization agreement with Israel that does not also include substantive progress on a political solution for the Palestinian cause will be difficult to advance.

Under the Leahy laws, the United States is prohibited from providing security assistance to any unit that is credibly accused of having committed a gross violation of human rights. Unlike almost all other recipients, which are vetted along these lines before they receive assistance, for Israel the process is reversed: The assistance is provided, and the United States then waits to receive reports of violations, assessing their credibility through a process known as the Israel Leahy vetting forum, which includes consultation with the government of Israel.

To date, the forum has never come to consensus that any Israeli security force unit or soldier has committed a gross violation of human rights — despite the findings of international human rights organizations

the U.S. failure to impose accountability on Israel for such violations may provide Israel with a sense of impunity, increasing the likelihood of gross violations of human rights (including those committed by settlers against Palestinian civilians) and further breaking the trust between Israel and Palestinians that would be needed for any sort of lasting peace.

Working on the ground with the authority, I saw how the major focus of U.S. efforts was to prove to the Israel Defense Forces that their Palestinian counterparts could be trusted to take on the mission of securing Israel

Palestinian intelligence officials would be provided with target information by Israel, and Palestinian forces would be expected to take on missions previously conducted by the Israel Defense Forces to detain those targets. This effort not only undermined Palestinian support for the authority but also failed to convince the Israelis, who saw any Palestinian courts’ (correct) refusal to hold Palestinian detainees without due process as proof of a revolving door in the system.

Even worse, in 2008 and ’09, when Israel’s Operation Cast Lead, which resulted in over 1,300 Palestinian deaths in Gaza, sparked protests in the West Bank, it was the Palestinian Authority Security Forces that physically stood between demonstrators and the Israel Defense Forces. From my balcony in Ramallah, I saw this as a proof of success and reported as much to Washington at the time. In hindsight, it was perhaps the death knell for the legitimacy of the Palestinian Authority in the eyes of its people.

If the United States is to continue to employ military and security assistance as a tool of its engagement in the Israeli-Palestinian conflict (and there are good arguments why it should not), it must change its approach significantly. One way to do this would be simply by applying the laws and policies that it applies to every other country in the world: There is no point in having leverage that could pressure Israel to cease actions that undermine peace if we refuse to even consider using it

The United States could also start conditioning its military assistance to Israel (as it does for many other recipients) on certain verifiable political conditions being met. In Israel’s case, these may include a halt to or dismantling of settlement infrastructure in the West Bank.

Another thing the U.S. might do is consider reframing its security assistance on the Palestinian side to reinforce, rather than undermine, the legitimacy of the Palestinian Authority

Doing so would require structuring assistance in a way that enables Palestinian society control over its own security forces. It would also require the recognition of Palestinian statehood

I resigned from my job because I do not believe that U.S. arms should be provided in a situation if we know they are more likely than not — in the words of the Biden administration’s own guiding policy — to lead to or to aggravate the risk of human rights violations, including widespread civilian harm and death.

“These are technologies that are supposed to be so democratized and universal, but they’re so heavily influenced by one person,”

“Everything they do is [framed as] a step toward much larger greatness and the transformation of society. But these are just cults of personality. They sell a product.”

during

“These are private-sector people making money off something that serves a public function. And when they take a turn because of very personal, very individual decisions, where a handful of people are shaping the trajectory of these companies, maybe even the existence of these companies, that’s something new we all have to deal with.”

where the other firms sold phones and search engines, Musk and Altman championed their work as a public mission for protecting mankind, with a for-profit business attached. It is notable that as private companies, they don’t have to report to federal regulators or to shareholders, who can vote down proposals or push back against their work.

The corporate storytelling that pushes technology as a force for public harmony has proved to be one of Silicon Valley’s great marketing tools, said Margaret O’Mara, a professor at the University of Washington who studies the history of technology. But it’s also obscured the dangers of centralizing power and subjecting it to leaders’ personal whim

“Silicon Valley has for years adopted this messaging and mood that it’s all about radical transparency and openness — remember Google’s ‘Don’t be evil’ motto? — and this idea of a kinder, gentle capitalism that’s going to change the world for the better,” she said.

“Then you have these moments of reckoning and remember: It’s capitalism. Some tech billionaires lost, and some other ones are winning,”

Jeff Hauser, the head of the left-leaning advocacy group Revolving Door Project, said in a statement Wednesday that Summers’s role on the board was a sign OpenAI was “unserious” about its oversight, and that it “should accelerate concerns that AI will be bad for all but the richest and most opportunistic amongst us.”

Ro Khanna, who represents parts of Silicon Valley, said in an interview that the OpenAI turmoil underscores concerns that “a few people, no matter how talented, no matter how knowledgeable, can’t be making the rules for a society on a technology that is going to have such profound consequences.”

“We’ve seen a parade of these big tech leaders come to D.C.,” Khanna said. “I think highly of them, but they’re not the ones who should be leading the conversation on the regulatory framework, what safeguards we need.”

Musk on Tuesday posted a message, under a picture of him holding a katana, saying, “There is a large graveyard filled with my enemies. I do not wish to add to it, but will if given no choice.”

The gripe drew a chagrined reply from Musk. “Unfortunately, the Internet (on which it is trained), is overrun with woke nonsense,” he responded. “Grok will get better. This is just the beta.”

While many tech ethicists and AI experts warn that these systems can absorb and reinforce harmful stereotypes, efforts by tech firms to counter those tendencies have provoked a backlash from some on the right who see them as overly censorial.

Touting xAI to former Fox News host Tucker Carlson in April, Musk accused OpenAI’s programmers of “training the AI to lie” or to refrain from commenting when asked about sensitive issues. (OpenAI wrote in a February blog post that its goal is not for the AI to lie, but for it to avoid favoring any one political group or taking positions on controversial topics.) Musk said his AI, in contrast, would be “a maximum truth-seeking AI,” even if that meant offending people.

So far, however, the people most offended by Grok’s answers seem to be the people who were counting on it to readily disparage minorities, vaccines and President Biden.

an academic researcher from New Zealand who examines AI bias, gained attention for a paper published in March that found ChatGPT’s responses to political questions tended to lean moderately left and socially libertarian. Recently, he subjected Grok to some of the same tests and found that its answers to political orientation tests were broadly similar to those of ChatGPT.

“I think both ChatGPT and Grok have probably been trained on similar Internet-derived corpora, so the similarity of responses should perhaps not be too surprising,”

Other AI researchers argue that the sort of political orientation tests used by Rozado overlook ways in which chatbots, including ChatGPT, often exhibit negative stereotypes about marginalized groups.

Musk and X did not respond to requests for comment as to what actions they’re taking to alter Grok’s politics, or whether that amounts to putting a thumb on the scale in much the same way Musk has accused OpenAI of doing with ChatGPT.

Now, students will participate in a jigsaw activity. Below are three articles about three different student populations that have been affected by the war in Ukraine. Assign each student, or have them choose, one of the articles to become an “expert” in. Make sure there are about an even number of students reading each article.

5. What are some of the fears or challenges teachers themselves are facing because of the war?6. You’ve read one of three articles about what education is like for a specific group of students. What role is school serving for the group you read about? Is there anything more schools could be doing to support these young people? If so, what and why?

What role can schools serve, even during war? How important do you think education is in a time like this? Do you believe educators should teach about what is happening in Ukraine? How do you think they should handle this sensitive subject?

Many teachers answered our call in mid-March to tell us how they were addressing the war in their classrooms. Here are some responses that show the many ways, large and small, that educators have sought to help their students understand the conflict and its roots, the plight of the Ukrainian people, the role of the United States and more. They have been edited for length and clarity.

I was shocked at how hungrily they soaked up the information, especially once Russia officially invaded Ukraine. These 10-, 11- and 12-year-olds wanted to learn more about what was happening in their world in the “right way” — via vetted news sources, exactly as you mentioned. After each episode, we discussed positives that we heard, we shared “wonders” (the things that we want to find more information on), and we shared one word to summarize the new information.

That day, my students’ remarks on the Russian invasion of Ukraine fit into five categories: empathy for the people of Ukraine, fear of World War III, criticism of Putin, criticism of memes that treat the invasion as a joke, and geopolitical curiosity.

Students then created infographics on Canva to illustrate their learning. Synthesizing that learning into smaller, digestible data bites helped them to make sense of such large, challenging concepts. Here are four examples of their work.

When discussing the conflict between Russia and Ukraine, that consisted of orienting everyone to where this conflict is happening geographically and what cities and countries are involved. We spoke about the history of NATO, key leaders, the concept of trade and supply chains — basically defining the common vocabulary and giving everyone the same tools for discussion.

That’s how I realized that my students needed to talk about the Russian invasion of Ukraine. As a result, I took the following steps the next day, with positive results.

As part of a larger project on the theme of “nostalgia,” students were asked to think of a family recipe that made them nostalgic. But we also talked about the food that brings us comfort no matter where we find ourselves. To help students connect to the Ukrainian people, we talked about the comforts of borscht with information from this article about a chef who is leading a drive to recognize the soup as a Ukrainian cultural heritage.

Teaching about Russia and Ukraine this spring encompassed history, vocabulary, maps, graphs, and photo analysis. We began with a brainstorm about what students had heard about what was happening with Ukraine and Russia. Then students moved on to define terms like Soviet Union, Cold War and NATO, and worked together to combine their definitions into one “best definition.” This vocabulary work set them up to read the Times article about what was happening in Ukraine as Russia invaded, annotating in the

Part of what has made the coverage of the war in Ukraine compelling is my students seeing visual inversions of their own lives. There’s a photo of a grandmother, but she’s holding an assault rifle. There are teenagers, not much older than they are, running drills. There’s a teacher, but instead of trying to manage a class, she’s barely managing to hold it together.

What do you notice about how the person is framed in the photograph?What is the posture? Where is their gaze?Imagine what they might be thinking as they gaze out of the frame.

This is an excellent piece to use when considering primary and secondary audiences, purpose, appeals, and overall effectiveness. It is also a story we can track to see if the speech moves anyone in Congress to change their position on the type of support to provide Ukraine.

Does the American government favor any countries over other countries? What is the policy that guides the American government when dealing with other countries?How does the American government handle disagreements with other countries?Which countries are American allies, or friends?Which are America’s traditional enemies? How is this determined? Does that history matter?

How does President Biden “create the enemy?” Why should America follow this course of action? What is he suggesting will happen if America does not? What does America stand to gain from this plan? Are potential losses discussed?Note patterns in rhetorical appeals, diction, values and themes. What assumptions does President Biden make about the American character or national identity? In what ways do American mythologies seem to bolster a “single story” of foreign policy?

As it turns out, technology demand only increased and the Nasdaq had its best year since 2009, spurred on by low interest rates and a surge in spending on products for remote work.

“Companies that recently raised at very high prices at the height of valuation inflation may be grappling with high burn rates and near-term challenges growing into those valuations,” Shakir told CNBC in an email. “Others that were more dilution-sensitive and chose to raise less may now need to consider avenues for extending runway that would have seemed unpalatable to them just months ago.”

“Our companies heeded that advice and most companies are now prepared for winter,” Lux wrote.

“This time, many of those tools have been exhausted,” Sequoia wrote. “We do not believe that this is going to be another steep correction followed by an equally swift V-shaped recovery like we saw at the outset of the pandemic.”Sequoia told its companies to look at projects, research and development, marketing and elsewhere for opportunities to cut costs. Companies don’t have to immediately pull the trigger, the firm added, but they should be ready to do it in the next 30 days if needed.

And among companies that are still private, staff reductions are underway at Klarna and Cameo, while Instacart is reportedly slowing hiring ahead of an expected initial public offering. Cloud software vendor Lacework announced staffing cuts on Friday, six months after the company was valued at $8.3 billion by venture investors.“We have adjusted our plan to increase our cash runway through to profitability and significantly strengthened our balance sheet so we can be more opportunistic around investment opportunities and weather uncertainty in the macro environment,” Lacework said in a blog post.

Shakir agreed with that assessment. “Like many, we at Lux have been advising our companies to think long term, extend runway to 2+ years if possible, take a very close look at reducing burn and improving gross margins, and start to set expectations that near-term future financings are unlikely to look like what they may have expected six or 12 months ago,” she wrote.

Lux highlighted one of the painful decisions it expects to see. For several companies, the firm said, “sacrificing people will come before sacrificing valuation.”But venture firms are keen to remind founders that great companies emerge from the darkest of times. Those that prove they can survive and even thrive when capital is in short supply, the thinking goes, are positioned to flourish when the economy bounces back.

The rule of law is an existential issue for the European Union: For the bloc to function properly, all member nations have to follow the same principles.

Laurent Pech, professor of European law at Middlesex University in London called the commitments “vague, partial and easy to evade.”

the invasion of Ukraine by President Vladimir Putin of Russia changed everything, tilting the balance of power in Europe and reshuffling alliances.

Reflecting how divisive the issue is in Brussels, two commissioners voted against the approval of Poland’s plan on Wednesday, a first since the recovery fund was established, and two others sent letters expressing concern over the move.

Last year, frustrated by Poland’s recalcitrance on judicial independence issues, the bloc started using the sharpest tool at its disposal: money, withholding much needed aid from the coronavirus fund.

“Poland simply deserves this money,” the country’s prime minister, Mateusz Morawiecki, told local media last week. “And now, with the war going on, Poland needs it even more.”

Poland and Hungary, led by right-wing authoritarian leaders who backed each other in conflicts with Brussels over the rule of law, took divergent paths following the Russian invasion. Under Prime Minister Viktor Orban, Hungary maintains close relations with Mr. Putin and has become a main spoiler of E.U. unity.

In response to the concerns by the European Commission, President Andrzej Duda of Poland put forward a bill amending the disciplinary system, which is expected to be approved by the Polish Parliament on Thursday.

But analysts say that Mr. Duda’s bill offers only cosmetic tweaks and does not resolve the fundamental issue identified by the European Court of Justice — pressure on judges to rule in accordance with the desires of the government.

Bush’s third big idea in the 2002 speech was to downgrade the importance of Afghanistan to the United States

The fourth core idea in the speech was a determination to regard terrorism as a tool of power.

it underscores that Instagram, WhatsApp and, increasingly, Reality Labs — the division tasked with developing virtual and augmented reality hardware and software — are the company’s future.

To understand how integral growth was to Facebook’s identity, it’s worth revisiting a memo that executive Andrew “Boz” Bosworth, now Meta’s CTO, sent to the company in 2016.

“The natural state of the world is not connected,” Bosworth wrote in the memo, which was leaked and published by BuzzFeed in 2018. “It is not unified. It is fragmented by borders, languages, and increasingly by different products. The best products don’t win. The ones everyone use [sic] win.”

Facebook’s “imperative,” in Bosworth’s telling — its raison d’etre — was to be that product that everyone used, the tool that unified at last a fragmented human race in a single, vast network. And the company would pursue that imperative at any cost, even the cost of users’ lives, “because that’s what we do,” he wrote. “We connect people.”

Wednesday’s earnings report showed that Facebook’s ascent has stalled just about everywhere. The biggest decline in daily usage was not in the United States but in a category that it calls “rest of world,” including Latin America and Africa.

Zuckerberg knew before just about anyone else that social media was no longer enough to keep the company on top. Now he’s trying to will into existence a grand new vision of a digital world in which we all have second lives that play out through avatars inhabiting virtual spaces and realms.

Several years ago, the company realized that it had saturated among U.S. and Canadian users, and it overhauled its core news feed algorithm to prioritize engagement — getting existing users to spend more time on the network.

losing users does not necessarily mean losing money in the short term: Facebook’s revenue per user also continued to grow last quarter.

Yet the end of Facebook’s growth era marks a turning point in the history of social media and the Internet. If Zuckerberg couldn’t connect the whole world with Facebook, given all the resources and momentum and desire one could ask for, he may have to confront the possibility that no single network ever will.

The fiscal response to Covid-19 reinforced this point: Money is a tool of social decision-making, not an objective thing that you get through abstract merit.

the value of cryptocurrency is so clearly socially constructed: A Bitcoin was worth roughly nothing a decade ago, and roughly $41,000 today, solely because people collectively decided to ascribe value to Bitcoin.

money gets its value from people agreeing that it’s valuable.

As of Friday Russia had about $630 billion of foreign currency reserves, a large cushion designed to allow it to withstand economic sanctions and prop up the value of the ruble

But “foreign currency reserves” are not an objective fact; they are mostly a series of entries on lists maintained by foreign-currency issuers and intermediaries (central banks, correspondent banks, sovereign bond issuers, brokerages). 1  If those people cross you off the list, or put an asterisk next to your entry freezing your funds, then you can’t use those funds anymore.

The bulk of Russia’s foreign reserves are held in the form of securities, deposits at other central banks and deposits at foreign commercial banks. A ban on transactions with Russia’s central bank means that it can’t sell those securities or access those deposits.

Now you want something for yourself? OK, but that is going to be subtracted from the running total of how much you’ve done for the rest for us.

There is a lot to dislike, or at least to be uncomfortable with, in this situation.

But the response to the 2008 global financial crisis, and to its later European aftershocks, made it clear that something else was going on. Who has money and what they can do with it can be adjusted by the actions of central banks and national treasuries; banks can be bailed out; costs can be socialized.

it is also arguably bad for global prosperity: Trustworthy rules-based trade works better and produces more value than arbitrary uncertain trade.

But what I want to suggest is that this weekend’s actions are evidence that the basic structure is good. What I want to suggest is that society is good, that it is good for people (and countries) to exist in a web of relationships in which their counterparties can judge their actions and punish bad actions.

If money is socially constructed and property is contingent then money is a continuing, dynamic, ever-at-risk reward for prosocial behavior.

one of the ways I suggest students think about money is as a kind of social scorecard.

You did something good — made something somebody wanted, let somebody else use something you own, went to work and did everything the boss told you? Good for you, you get a cookie. Or more precisely, you get a credit, in both senses, in the personal record kept for you at a bank.

This is arguably bad for the dollar’s long-run dominance: Russia will develop its own ways around SWIFT, China will push other countries to adopt its digital yuan, everyone will use Bitcoin, etc

we have exactly this system already. The number is called a bank account. The difference is simply that we have so naturalized the system that “how much money you have” seems like simply a fact about you, rather than a judgment imposed by society.

Pervasive social credit systems seem dystopian, and you would not really want the U.S. government making day-to-day decisions about who deserves to keep their bank accounts.

But another idea is that money can insulate you from  the obligations of society, and that is also bad.

You get a claim on goods and services by being part of society, and having a big number next to your name on a list does not relieve you of your obligations. If you do something so outrageous that society as a whole decides you are a pariah, then money is a way for society to express that.

A chat app can be social like a huddle of people in focused conversation. Participants are speaking to be heard by one another, not by the entire world. There is more concentration and potential for intimacy, and much less performance.

For Ukrainians and Russians resisting the war, the different ways of engaging through Telegram—receiving information through dedicated channels, forming groups committed to one topic, or chattering in hushed tones—benefit a people that will likely have to sustain a long insurgency.

It was, Salem wrote, “group-think on steroids—an abomination of a monster with thousands of arms and no brain.”

Chat apps are merely the latest expression of the smaller, more controlled spaces that have always been central to incubating new ideas or challenging existing ones.

in the Soviet Union, samizdat played this role. The underground, illegal, and self-produced writing, passed hand to hand, kept alive a shadow civil society during repressive periods.

The lineage of such underground communication stretches across history, from the 17th-century scholars in Europe who collaborated through letters on scientific experiments in defiance of Church doctrine all the way to the xeroxed and stapled zines of the 1990s, which set the tone of third-wave feminism.

What matters is that embattled Ukrainians and anti-war Russians are attempting to practice privacy and quiet communication—necessary virtues for a resistance movement.

While there are substitutes for Russian nickel, there’s no good substitute for the U.S. dollar and U.S. technology. It is very hard to get paid for things you sell if you can’t use SWIFT messaging and have been cut off by the U.S. regulated financial institutions that “clear” transactions in dollars. And it’s hard to build sophisticated machines without semiconductors that are made with U.S. intellectual property.

The barrier isn’t just that the payment networks of Russia and China are three or four decades behind. Others also fear how they would abuse these networks if they controlled them. The United States has its problems, but it at least provides some legal protections to businesses and countries that have fallen afoul of its harsh measures.

Often, U.S. officials treat these rules as an obstacle preventing them from taking strong actions. Yet these restrictions provide America with a strategic advantage: They give foreign countries and businesses some reason for trust.

Overreach, then, is the more immediate threat

they illustrate a deeper danger. As a new book by the historian Nicholas Mulder emphasizes, the “economic weapon” of sanctions and blockades doesn’t work nearly as predictably or effectively as its proponents imagine. The more powerful sanctions are, the greater the danger that they will lead to an unpredictable response. As Mr. Mulder demonstrates, fears of sanctions helped propel Nazi Germany’s territorial ambitions

measures should be just harsh enough to reach specific goals: to protect Ukrainian independence and to limit, to the greatest extent possible, Russia’s aggressive gains.

The United States should also explicitly lay out the circumstances under which the executive branch will apply such economic measures, the range of permissible goals that they can accomplish, the review procedures that will ensure they are proportionate and the circumstances under which they will be withdrawn.

that would be on par with what we experience with flu viruses, which scientists estimate hit us about every two to five years, less often in adulthood. It also matches up well with the documented cadence of the four other coronaviruses that seasonally trouble humans, and cause common colds.

For now, every infection, and every subsequent reinfection, remains a toss of the dice. “Really, it’s a gamble,” says Ziyad Al-Aly, a clinical epidemiologist and long-COVID researcher at Washington University in St. Louis. Vaccination and infection-induced immunity may load the dice against landing on severe disease, but that danger will never go away completely, and scientists don’t yet know what happens to people who contract “mild” COVID over and over again

Or maybe not. This virus seems capable of tangling into just about every tissue in the body, affecting organs such as the heart, brain, liver, kidneys, and gut; it has already claimed the lives of millions, while saddling countless others with symptoms that can linger for months or years.

considering our current baseline, “less dangerous” could still be terrible—and it’s not clear exactly where we’re headed. When it comes to reinfection, we “just don’t know enough,”

Perhaps, as several experts have posited since the pandemic’s early days, SARS-CoV-2 will just become the fifth cold-causing coronavirus.

A third or fourth bout might be more muted still; the burden of individual diseases may be headed toward an asymptote of mildness that holds for many years

Future versions of SARS-CoV-2 could continue to shape-shift out of existing antibodies’ reach, as coronaviruses often do. But the body is flush with other fighters that are much tougher to bamboozle—among them, B cells and T cells that can quash a growing infection before it spirals out of control

Those protections tend to build iteratively, as people see pathogens or vaccines more often. People vaccinated three times over, for instance, seem especially well equipped to duke it out with all sorts of SARS-CoV-2 variants, including Omicron and its offshoots.

promising patterns: Second infections and post-vaccination infections “are significantly less severe,” she told me, sometimes to the point where people don’t notice them at all

Bodies, wised up to the virus’s quirks, can now react more quickly, clobbering it with sharper and speedier strikes.

“There are still very good reasons” to keep exposures few and far between, Landon, of the University of Chicago, told me. Putting off reinfection creates fewer opportunities for harm: The dice are less likely to land on severe disease (or chronic illness) when they’re rolled less often overall. It also buys us time to enhance our understanding of the virus, and improve our tools to fight it.

Immunity, though, is neither binary nor permanent. Even if SARS-CoV-2’s assaults are blunted over time, there are no guarantees about the degree to which that happens, or how long it lasts.

A slew of factors could end up weighting the dice toward severe disease—among them, a person’s genetics, age, underlying medical conditions, health-care access, and frequency or magnitude of exposure to the virus.

for everyone else, no amount of viral dampening can totally eliminate the chance, however small it may be, of getting very sick.

Long COVID, too, might remain a possibility with every discrete bout of illness. Or maybe the effects of a slow-but-steady trickle of minor, fast-resolving infections would sum together, and bring about the condition.

Every time the body’s defenses are engaged, it “takes a lot of energy, and causes tissue damage,” Thomas told me. Should that become a near-constant barrage, “that’s probably not great for you.”

Bodies are resilient, especially when they’re offered time to rest, and she doubts that reinfection with a typically ephemeral virus such as SARS-CoV-2 would cause mounting damage. “The cumulative effect is more likely to be protective than detrimental,” she said, because of the immunity that’s laid down each time.

people who have caught the virus twice or thrice may be more likely to become long-haulers than those who have had it just once.

Some other microbes, when they reinvade us, can fire up the immune system in unhelpful ways, driving bad bouts of inflammation that burn through the body, or duping certain defensive molecules into aiding, rather than blocking, the virus’s siege. Researchers don’t think SARS-CoV-2 will do the same. But this pathogen is “much more formidable than even someone working on coronaviruses would have expected,

Seasonal encounters with pathogens other than SARS-CoV-2 don’t often worry us—but perhaps that’s because we’re still working to understand their toll. “Have we been underestimating long-term consequences from other repeat infections?” Thomas said. “The answer is probably, almost certainly, yes.”

the rhythm of reinfection isn’t just about the durability of immunity or the pace of viral evolution. It’s also about our actions and policies, and whether they allow the pathogen to transmit and evolve. Strategies to avoid infection—to make it as infrequent as possible, for as many people as possible—remain options, in the form of vaccination, masking, ventilation, paid sick leave, and more.

Gordon and Swartz are both hopeful that the slow accumulation of immunity will also slash people’s chances of developing long COVID.

The outlooks of the experts I spoke with spanned the range from optimism to pessimism, though all agreed that uncertainty loomed. Until we know more, none were keen to gamble with the virus—or with their own health. Any reinfection will likely still pose a threat, “even if it’s not the worst-case scenario,” Abdool Karim told me. “I wouldn’t want to put myself in that position.”

“I don’t see anything wrong with it; I don’t blame other people for doing it,” Carter says over dinner. “It just never had been my ambition to be rich.”

Carter decided that his income would come from writing, and he has written 33 books, about his life and career, his faith, Middle East peace, women’s rights, aging, fishing, woodworking, even a children’s book written with his daughter, Amy Carter, called “The Little Baby Snoogle-Fleejer.”

Carter costs U.S. taxpayers less than any other ex-president, according to the General Services Administration, with a total bill for him in the current fiscal year of $456,000, covering pensions, an office, staff and other expenses.

Carter is the only president in the modern era to return full-time to the house he lived in before he entered politics — a two-bedroom rancher assessed at $167,000, less than the value of the armored Secret Service vehicles parked outside.

Ex-presidents often fly on private jets, sometimes lent by wealthy friends, but the Carters fly commercial. Stuckey says that on a recent flight from Atlanta to Los Angeles, Carter walked up and down the aisle greeting other passengers and taking selfies.

“He doesn’t like big shots, and he doesn’t think he’s a big shot,” said Gerald Rafshoon, who was Carter’s White House communications director.

With book income and the $210,700 annual pension all former presidents receive, the Carters live comfortably. But his books have never fetched the massive sums commanded by more recent presidents.

The federal government pays for an office for each ex-president. Carter’s, in the Carter Center in Atlanta, is the least expensive, at $115,000 this year. The Carters could have built a more elaborate office with living quarters, but for years they slept on a pullout couch for a week each month. Recently, they had a Murphy bed installed.

Carter doesn’t even have federal retirement health benefits because he worked for the government for four years — less than the five years needed to qualify, according to the GSA. He says he receives health benefits through Emory University, where he has taught for 36 years.

Carter’s office costs a fraction of Obama’s, which is $536,000 a year. Clinton’s costs $518,000, George W. Bush’s is $497,000 and George H.W. Bush’s is $286,000, according to the GSA.

“He didn’t feel suited to the grandeur,” Eizenstat said. “Plains is really part of his DNA. He carried it into the White House, and he carried it out of the White House.”

“I am a great admirer of Harry Truman. He’s my favorite president, and I really try to emulate him,” says Carter, who writes his books in a converted garage in his house. “He set an example I thought was admirable.”

The Jimmy Carter National Historic Site is essentially the entire town, drawing nearly 70,000 visitors a year and $4 million into the county’s economy.

Carter has used his post-presidency to support human rights, global health programs and fair elections worldwide through his Carter Center, based in Atlanta. He has helped renovate 4,300 homes in 14 countries for Habitat for Humanity, and with his own hammer and tool belt, he will be working on homes for low-income people in Indiana later this month.

Carter’s gait is a little unsteady these days, three years after a diagnosis of melanoma on his liver and brain. At a 2015 news conference to announce his illness, he seemed to be bidding a stoic farewell, saying he was “perfectly at ease with whatever comes.”

In October, he will become the second president ever to reach 94; George H.W. Bush turned 94 in June. These days, Carter is sharp, funny and reflective.

The Carters walk every day — often down Church Street, the main drag through Plains, where they have been walking since the 1920s.

“I grew up in church with him,” says Maya Wynn. “He’s a nice guy, just like a regular person.”

“He’s a good ol’ Southern gentleman,” says David Lane.

Carter says this place formed him, seeding his beliefs about racial equality. His farmhouse youth during the Great Depression made him unpretentious and frugal. His friends, maybe only half-joking, describe Carter as “tight as a tick.”

That no-frills sensibility, endearing since he left Washington, didn’t work as well in the White House. Many people thought Carter scrubbed some of the luster off the presidency by carrying his own suitcases onto Air Force One and refusing to have “Hail to the Chief” played.

Stuart E. Eizenstat, a Carter aide and biographer, said Carter’s edict eliminating drivers for top staff members backfired. It meant that top officials were driving instead of reading and working for an hour or two every day.

That’s less than half the $952,000 budgeted for George H.W. Bush; the three other living ex-presidents — Clinton, George W. Bush and Obama — cost taxpayers more than $1 million each per year.

When Carter looks back at his presidency, he says he is most proud of “keeping the peace and supporting human rights,” the Camp David accords that brokered peace between Israel and Egypt, and his work to normalize relations with China. In 2002, he was awarded the Nobel Peace Prize for his efforts.

“I always told the truth,” he says.

Carter says he thinks the Supreme Court’s Citizens United decision has “changed our political system from a democracy to an oligarchy. Money is now preeminent. I mean, it’s just gone to hell now.”

He says he believes that the nation’s “ethical and moral values” are still intact and that Americans eventually will “return to what’s right and what’s wrong, and what’s decent and what’s indecent, and what’s truthful and what’s lies.”

They are asked if there is anything they want but don’t have. “I can’t think of anything,” Carter says, turning to Rosalynn. “And you?” “No, I’m happy,” she says.

They watch Atlanta Braves games or “Law and Order.” Carter just finished reading “The Innovators” by Walter Isaacson. They have no chef and they cook for themselves, often together. They make their own yogurt.

The U.S. logs fewer than 1,000 annual deaths out of millions of documented cases

this is more a nauseating nuisance than a public-health crisis. In most people, norovirus triggers, at most, a few miserable days of GI distress that can include vomiting, diarrhea, and fevers, then resolves on its own; the keys are to stay hydrated and avoid spreading it to anyone vulnerabl

norovirus is the most common cause of foodborne illness in the United States.)

the virus is far more deadly in parts of the world with limited access to sanitation and potable water.

Still, fighting norovirus isn’t easy, as plenty of parents can attest. The pathogen, which prompts the body to expel infectious material from both ends of the digestive tract, is seriously gross and frustratingly hardy. Even the old COVID standby, a spritz of hand sanitizer, doesn’t work against it—the virus is encased in a tough protein shell that makes it insensitive to alcohol.

At an extreme, a single gram of feces—roughly the heft of a jelly bean—could contain as many as 5.5 billion infectious doses, enough to send the entire population of Eurasia sprinting for the toilet.

norovirus mainly targets the gut, and spreads especially well when people swallow viral particles that have been released in someone else’s vomit or stool.

direct contact with those substances, or the food or water they contaminate, may not even be necessary: Sometimes people vomit with such force that the virus gets aerosolized; toilets, especially lidless ones, can send out plumes of infection

If the spittle finding holds for humans, then talking, singing, and laughing in close proximity could be risky too.

Once emitted into the environment, norovirus particles can persist on surfaces for days—making frequent hand-washing and surface disinfection key measures to prevent spread

Handshakes and shared meals tend to get dicey during outbreaks, along with frequently touched items such as utensils, door handles, and phones.

One 2012 study pointed to a woven plastic grocery bag as the source of a small outbreak among a group of teenage soccer players; the bag had just been sitting in a bathroom used by one of the girls when she fell sick the night before.

Once a norovirus transmission chain begins, it can be very difficult to break. The virus can spread before symptoms start, and then for more than a week after they resolve

Once the virus arrives, the entire family is almost sure to be infected. Baldridge, who has two young children, told me that her household has weathered at least four bouts of norovirus in the past several years.

Roughly 20 percent of European populations, for instance, are genetically resistant to common norovirus strains. “So you can hope,” Frenck told me. For the rest of us, it comes down to hygiene

Altan-Bonnet recommends diligent hand-washing, plus masking to ward off droplet-borne virus. Sick people should isolate themselves if they can. “And keep your saliva to yourself,” she told me.

The family fastidiously scrubbed their hands with hot water and soap, donned disposable gloves when touching shared surfaces, and took advantage of the virus’s susceptibility to harsh chemicals and heat. When her son threw up on the floor, Cameron sprayed it down with bleach; when he vomited on his quilt, she blasted it twice in the washing machine on the sanitizing setting, then put it through the dryer at a super high temp

After three years of COVID, the world has gotten used to thinking about infections in terms of airways. “We need to recalibrate,” Bhumbra told me, “and remember that other things exist.”

ALL THREE REPORTS INCLUDE quintessentially Trumpian scenes, consistent in their depictions of the former president’s methods, and very much in keeping with numerous journalistic accounts of how he sought to manipulate people, rules and institutions.

The three investigations tell different stories, but the misdeeds all run together, more overlapping than sequential

Still, each investigation offers a slightly different theory of Trump. In the Mueller report, Trump and his aides come across as the gang that can’t cheat straight — too haphazard to effectively coordinate with a foreign government, too ignorant of campaign finance laws to purposely violate them, often comically naïve about the gravity of their plight.

The Ukraine report, by contrast, regards Trump as more strategic than chaotic, and it does not wallow in the netherworld between the president’s personal benefit and his public service. “The president placed his own personal and political interests above the national interests of the United States, sought to undermine the integrity of the U.S. presidential election process, and endangered U.S. national security,”

All three reports show Trump deploying the mechanisms of government for political gain.

The Mueller report argues that viewing the president’s “acts collectively can help to illuminate their significance.” The Ukraine report shows that the conversation that Trump described as “a perfect call” was not the ask; it was the confirmation. When Trump said, “I would like you to do us a favor, though,” Zelensky and his aides had already been notified of what was coming. The Ukraine scandal was never about a single call, just as the Jan. 6 report was not about a single day.

The Jan. 6 report takes seriously the admonition to view the president’s actions collectively, not individually; the phrase “multipart plan” appears throughout the report, with Trump as the architect.

Even more so than the Ukraine report, the Jan. 6 report repeatedly emphasizes how Trump knew, well, everything

There is no room here for the plausible deniability that the Mueller report entertained, for the notion that Trump didn’t know better, or that, in the immortal words of Attorney General William P. Barr when he creatively interpreted the Mueller report to exonerate Trump of obstruction of justice, that the president was “frustrated and angered by his sincere belief that the investigation was undermining his presidency.”

This alleged sincerity underscored the president’s “noncorrupt motives,” as Barr put it. In the Jan. 6 report, any case for Trumpian sincerity is eviscerated in a six-page chart in the executive summary, which catalogs the many times the president was informed of the facts of the election yet continued to lie about them. “Just say the election was corrupt and leave the rest to me and the Republican congressmen,” Trump told top Department of Justice officials in late December 2020, the report says.

Just announce an investigation into the Bidens. Just say the 2020 election was rigged. Trump’s most corrupt action is always the corruption of reality.

The studious restraint of the Mueller report came in for much criticism once the special counsel failed to deliver a dagger to the heart of the Trump presidency and once the document was so easily miscast by interested parties

for all its diffidence, there is power in the document’s understated prose, in its methodical collection of evidence, in its unwillingness to overstep its bounds while investigating a president who knew few bounds himself.

The Ukraine and Jan. 6 reports came at a time when Trump’s misconduct was better understood, when Mueller-like restraint was less in fashion and when those attempting to hold the chief executive accountable grasped every tool at hand. For all their passion and bluntness, they encountered their own constraints, limits that are probably inherent to the form

His dissertation at Berkeley turned into a book, “The Whole World Is Watching: Mass Media in the Making and Unmaking of the New Left,” published in 1980 and revised in 2003. In it, he traced the media’s symbiotic role in political movements, S.D.S. in particular.

His well-received “Inside Prime Time” (1983, revised in 1994), for which he interviewed 200 people in the television industry, showed how advertisers and network executives colluded to set the cultural agenda.

Spotify doesn’t have those things to turn to. So it’s been turning to podcasts. Besides enticing new subscribers with Spotify-branded podcasts—Rogan and Gimlet Media at the forefront of these—Spotify gets a new place to run ads. The podcast-advertising ecosystem is still lush enough to support additional harvesting. Spotify is betting that what used to be known as the music industry is in fact dead but that maybe the company can make money in the “audio industry.” But that shift involves decisions that disappoint even people jaded by years of experience with the recording business.

In the context of the devaluation of so many artists’ work, the backing of Rogan feels like a particularly nihilistic move. Spotify didn’t sign him for his talent or care at all about his impact—good or ill—on the world; with a heartless, almost video-game sensibility, they signed him to take market share from Apple and Google

Complaints against bloodless businessmen are hardly new. But what’s happening in music today feels less like individual acts of exploitation and more like the razing of an ecosystem.

When Rogan announced his signing, he emphasized that Spotify would have no creative control over his podcast. He was agreeing to a licensing deal, but he wouldn’t be an employee. “It will be the exact same show,” Rogan claimed

His comments fell somewhere between the gentle vibe of “Look, man, they’re offering me $100 million, so, uh, what am I supposed to do?” and a more aggressive “Spotify doesn’t own me, man. They are renting me for a certain period of time for $100 million—that’s different.” It’s infuriating that Rogan’s podcast has the trappings of counterculture while finding itself in such particular proximity to money and tech power. But I don’t know that, if I were Rogan, I would do much different.

Others in the “audio industry” face more discouraging trends. I suspect that the big record companies would dissolve if they weren’t still making so much money off the music of the 20th century.

I knew a lot of bands in the early 2000s whose members could quit their day job for a few years and make a living on relatively small amounts of record sales coupled with touring

Today, fewer artists are crossing the bar of being able to live purely off making and performing music. A lot of artists are failing to find a place in an “audio industry” that ever more efficiently mines smaller veins for what little cash can be extracted, or in a broader entertainment industry that has more in common with Marvel-movie spectacle than any particular sort of artistry.

My deep dread, though, is that this ability to tune out and focus on art becomes an aristocratic luxury; that a lack of money for music means a lack of money for musicians; that new ways of doing business are destroying the possibility of a creative middle class.

Solidarity is a tempting response to technological change, but my tired brain just can’t see the mechanism for it in this era. I honestly feel like a master sock weaver at the start of the industrial revolution. People will still get their socks, maybe worse than the ones before. And in the end, technology will plow us over.

Russian President Vladimir Putin is demanding that the West rewrite the post-Cold War security arrangements for Europe and demonstrated that Russia has the military capability to impose its will despite Western objections and economic sanctions.

“We all thought we were looking at a Europe whole, free and at peace indefinitely,” said Michele Flournoy, who served as the Pentagon’s top policy official during the Obama administration. “We knew that Russia would conduct gray zone operations and that Putin would use his KGB playbook to create instability on his periphery. But a wholesale invasion of a sovereign country to reorient its government is a different moment.”

“And we’re seeing that while Beijing doesn’t really like Putin’s tactics, they’re willing to band together as authoritarian states against the Western democracies,” Ms. Flournoy added. “We are going to see more and more of that in the future.”

China’s Communist Party leadership also saw pro-democracy protest movements in former Soviet republics as U.S.-engineered plots that could ultimately be used against Beijing.

For much of the past decade, the U.S. security establishment began taking note of what the Pentagon in 2015 called the “re-emergence of great power competition” and shifted from its emphasis of counterterrorism operations in the Middle East and Southwest Asia.

Defense Secretary Lloyd Austin has repeatedly cast China as the “pacing challenge” while Russia was seen as the lesser longer-term danger.

Even with annual defense budgets that soared over $700 billion, coping with an urgent Russian-generated crisis while preparing for a Chinese threat whose peak is still years away presents an enormous challenge for the Pentagon.

”The United States is particularly at risk of being overwhelmed should its military be forced to fight on two or more fronts simultaneously,” said a Congressionally mandated study of the Pentagon’s strategy that was issued in 2018

The era of nuclear reductions may come to an end as the U.S. military establishment argues for a large enough nuclear arsenal to deter both Russia’s formidable nuclear weaponry and China’s rapidly growing nuclear forces, which aren’t limited by any arms-control agreement.

“The United States is going to have to get used again to operating in multiple theaters simultaneously—not just militarily, but in terms of psychology and foreign-policy making,”

Already, debates are emerging among U.S. defense experts on whether the Pentagon should give equal weight to the twin challenges from Beijing and Moscow or focus more on the Pacific.

Should the West impose crippling sanctions on Russian banks and major companies, Moscow is likely to become more reliant on Beijing, which has issued a digital currency and is building a payments system separate from the West’s.

“It is already ending the amnesia about the importance of energy security,” said Daniel Yergin, vice chairman of research firm IHS Markit. “It means a new emphasis on diversification of energy sources for Europe and a new look at U.S. domestic and international energy policies.”

Advocates of using energy as a geopolitical tool say Washington should promote investment in U.S. oil and natural gas and approve new LNG export terminals and pipelines in the United States.

The 1997 NATO-Russia Founding Act precludes the alliance from permanently stationing additional substantial combat forces on the territory of its new Eastern and Central European members, but could now be repealed.

A recent poll by the European Council on Foreign Relations noted most Europeans see the Ukraine crisis as a broader threat to Europe. Some current and former officials, however, worry that the alliance’s solidarity could fray in the years ahead as it debates the need for greater military spending and wrestles whether its military ties with Georgia might stir new confrontations with Moscow.

the Alphen Group by former officials and other experts urges that European members of the alliance and Canada provide for 50% of NATO’s minimum military requirements by 2030 so the U.S. can focus more on deterring China.

“Everybody’s unified right now and outraged about what the Russians are doing,” said Alexander Vershbow, a former U.S. ambassador to NATO who also served as the alliance’s deputy secretary-general from 2012 to 2016. “But when we get down to making longer-term commitments to strengthen NATO’s defense posture and potentially revisit nuclear issues, it could become very divisive.”
