Russia’s foreign intelligence chief says attempts by NATO countries to help Ukraine will not go unpunished.

European nations say Russia deploying 'hybrid activities' against NATO and EU, but haven't blamed Moscow for incidents.

“On the record? We’re as calm as calm can be,” a European official assured me last week when I called him to ask what he thought about the reelection of Donald Trump.

His answer surprised me. I’d first met the official earlier this year when I was reporting on European allies’ view of the U.S. presidential election. Back then, almost every leader and diplomat I interviewed expressed dread at the prospect of Trump’s return to power; this same official had described the stakes as “existential” for his country. The reasons for the anxiety were obvious: Russia was waging war on NATO’s doorstep, and America, the alliance’s most powerful member by far, appeared to be on the verge of reelecting a president who had, among other things, said he’d encourage Russia to “do whatever the hell they want” to NATO countries he considers freeloaders. Yet now, the official on the other end of the line was talking optimistically about the “transatlantic cooperation” his government looked forward to fostering with its partners in Washington, and “working toward strong relationships with the new administration.”

“We approach the next Trump presidency with calm and focus, not wobbling and panic,” he confidently declared.

Then he asked if he could speak anonymously. I agreed. “Obviously,” he said, “a million things could go wrong.”

Political leaders and diplomats across Europe are clear-eyed about the threat that the next president will pose—and yet they can do very little about it. “The overall level of anxiousness is fairly high,” the official told me. “People are expecting turbulence.” America’s allies now know that they can’t simply ride out a Trump term and wait for a snap back to normalcy. So far this century, Americans have elected George W. Bush, Barack Obama, Donald Trump, Joe Biden, and Trump again. “Predictability is gone,” he said. “The pendulum swings from one extreme to the other.”

In the short term, sources told me, the plan is to cozy up to Trump and those close to him and hope for the best. In the long term, a growing consensus has emerged that Europe will need to prepare for a world in which it no longer counts on America for protection.

Wolfgang Ischinger, a veteran German diplomat who has served as ambassador to the United States, is among those urging calm. He has publicly cautioned European leaders against “finger wagging” in their interactions with the president-elect, and said they should take a wait-and-see approach when it comes to Trump’s foreign policy. Like other Europeans I spoke with, he was relieved by the choice of Marco Rubio—who has signaled support for NATO and has traditional views of America’s role in the world—for secretary of state. Ischinger also welcomed the realism that has shaped Europe’s response so far to Trump’s reelection. “We’re just going to have to deal with him—we’re prepared to deal with him.”

European officials, who have spent years planning for this contingency, are working to deepen personal relationships with Trump’s Republican allies, Ischinger told me, and talking about gestures they could make to flatter him. But these efforts will almost certainly face resistance from the European public, which, he said, broadly finds Trump repellent and even sinister. “I see a lot of disdain and panic,” he told me.

These reactions were reflected in the postelection headlines in the European press, which greeted Trump’s return with a mix of bafflement, scorn, and Apprentice puns. “What Have They Done … Again?” asked the cover of Britain’s Daily Mirror. The Guardian plastered its cover with the words “American dread.” And an op-ed on the homepage of the German newspaper Die Zeit resorted to English to capture the moment with a four-letter headline: “Fuck.”

Behind the scenes, Ischinger told me, European leaders have discussed inviting Trump to a capital for a grand state visit where allies could roll out the red carpet and hopefully cultivate some good will. But Ischinger worries that such an attempt could backfire. “I cannot imagine any such scenario in any German-French-Spanish-Italian city where you would not have huge anti-Trump demonstrations, probably really ugly ones,” he told me. “Organizing a decent visit for Mr. Trump would really be quite a nightmare for the police.”

Ischinger told me that the return of Trump and his hard-edged “America First” policy is emboldening Europeans who have been arguing that the continent needs more independence from its most powerful ally. Ischinger himself seems to be listening. When we spoke earlier this year, he was somewhat dismissive of the idea that Europe could chart a post-America course, at least in the near term. “Dreaming about strategic autonomy for Europe is a wonderful vision for maybe the next 50 years,” he told me in March. “But right now, we need America more than ever.”

Last week, though, he spoke urgently of the need for Europe to start manufacturing more of its own weapons and get serious about being able to defend its borders. “Are we finally going to wake up to the fact that we cannot rely forever on being protected by the United States?” he asked. He said he doesn’t believe that Trump will move to withdraw from NATO, but the fact that it’s even a question puts Europe in a deeply precarious position. The U.S. has more troops stationed in Europe (about 85,000) than the entire militaries of Belgium, Sweden, and Portugal combined. It provides essential air-force, intelligence-gathering, and ballistic-missile defense capabilities; covers about 16 percent of NATO’s operating costs; and manufactures most of the weapons that are bought by European militaries. Ischinger said that the situation is untenable: It’s just too risky to rely indefinitely on American military might to deter Russian aggression in the region. “We have a war now. This is urgent—this is not just political theory,” he told me. “This is a decisive moment in European history.”

Meanwhile, some in Europe are looking beyond the immediate military implications of Trump’s election. At Faith Angle Europe, an annual conference hosted last week by the Aspen Institute in France, journalists and scholars from both sides of the Atlantic gathered in a resort on the French Riviera and, in between pastry buffets and dips in the pool, contemplated the potential end of liberal democracy in America. To many in Europe, Trump’s election looks less like a historical fluke or “black swan event” and more like the climactic achievement of a right-wing populism that has been upending politics on their continent for much of this century—the same forces that led to Brexit in the United Kingdom, brought Giorgia Meloni to power in Italy, and made Marine Le Pen a major player in France. Not all Europeans, of course, are put off by the brand of politics that Trump represents

Nathalie Tocci, an Italian political scientist who has worked as an adviser for the ministry of foreign affairs and the European Union, predicted that Trump’s victory would “galvanize” far-right movements around the world. “They feel they really are on a roll, and they probably are,” she told attendees at the conference. “There’s a sense of legitimization … If this is happening in the heart of liberal democracy, surely you can’t make the argument that this happening in Europe is undemocratic.”

In recent years, Tocci said, far-right leaders in Europe were on their best behavior, eager not to alienate America by, say, airing their real views about Putin and Ukraine. Now that Biden, a classic transatlanticist, is set to be replaced with Trump, she said, “there’s going to be quite a lot of lowering of the masks.”

Bruno Maçães, a writer and consultant on geopolitics who has served as Portugal’s Europe minister, told me his phone had been ringing constantly since Trump’s election. European business leaders want to know what Trump will do with his second term, and how they can prepare. Maçães was not optimistic. He scoffed at Trump’s decision to create new, lofty-sounding administration posts for Elon Musk and Vivek Ramaswamy, and was baffled by the Silicon Valley types who believe the billionaires will transform the federal government, usher in a new era of unprecedented economic growth, and colonize Mars. “Maybe,” Maçães said. “I don’t know. But if you saw this in another country, you would see it as an acute sign of political decay when billionaires and oligarchy are taking over political policy.”

Maçães, like others I talked with, was eager not to be seen as hysterical or fatalistic. He said he didn’t think Trump’s foreign-policy appointments so far have been disastrous. But when he looked at the people Trump was naming to key domestic positions, most notably Matt Gaetz as attorney general, he found it hard to see anything other than a profound deterioration of political culture and democratic norms. “Americans have more reason to worry than the rest of the world,” he said.

Part of NATO's broader missile shield, the base could alleviate concerns for European security once Trump takes office.

Russian drone and missile strikes on Ukrainian targets have increased in frequency in the week since the U.S. election, killing civilians and destroying another dam. Russian troops continued to make incremental gains toward the city of Pokrovsk. The Russian army is preparing a new offensive, this time using North Korean troops. Russian President Vladimir Putin congratulated Donald Trump on his election but implied that he would have discussions only if the U.S. initiates talks, drops its sanctions, and refuses to offer any further support for Ukraine—accepting, in other words, a Russian victory. Meanwhile, Russian state television welcomed news of the election by gleefully showing nude photographs of Melania Trump on the country’s most-watched channel.

How will the new U.S. administration respond? What should the outgoing administration do?

In one sense, nothing will change. For nearly three years, many, many people, from the right to the left, in Europe and in America, have called for negotiations to end the Russian invasion of Ukraine. The Biden administration repeatedly probed the possibility of negotiations. The German government endlessly proposed negotiations. Now a new team will arrive in Washington, and it will be demanding negotiations too.

[Read: Helping Ukraine is Europe’s job now]

The new team will immediately run into the same dilemma that everyone else has encountered: “Land for peace” sounds nice, but the president of Russia isn’t fighting for land. Putin is fighting not to conquer Pokrovsk but to destroy Ukraine as a nation. He wants to show his own people that Ukraine’s democratic aspirations are hopeless. He wants to prove that a whole host of international laws and norms, including the United Nations Charter and the Geneva conventions, no longer matter. His goal is not to have peace but to build concentration camps, torture civilians, kidnap 20,000 Ukrainian children, and get away with it—which, so far, he has.

Putin also wants to show that America, NATO, and the West are weak and indecisive, regardless of who is president, and that his brutal regime represents some kind of new global standard. And now, of course, he also needs to show his country that nearly three years of fighting had some purpose, given that this costly, bloody, extended war, officially described as nothing more than a “special military operation,” was supposed to end in a matter of days. Maybe Putin could be interested in stopping the fight for some period of time. Maybe he could be threatened into halting his advance, or bribed with an offer of sanctions relief. But any cease-fire treaty that does not put some obstacle—security guarantees, NATO troops in Ukraine, major rearmament—in the way of another invasion will fail sooner or later because it will simply give Russia an opportunity to rest, rearm, and resume pursuit of the same goals later on.

Putin will truly stop fighting only if he loses the war, loses power, or loses control of his economy. And there is plenty of evidence that he fears all three, despite his troops’ slow movement forward. He would not have imported thousands of North Korean soldiers if he had an infinite number of Russians to replace the more than 600,000 soldiers whom he has lost to injury or death. He would not have paid American YouTubers to promote anti-Ukrainian propaganda if he wasn’t worried by the American public’s continued support for Ukraine. His economy is in trouble: Russian inflation is rising fast; Russian interest rates are now at 21 percent; Russian industries particularly vulnerable to sanctions, such as liquefied natural gas, are suffering. The Russian navy was humiliated in the Black Sea. The Russian military has still not recaptured territory lost in Russia’s Kursk province, conquered by the Ukrainians last summer.

When the next U.S. president, secretary of defense, and secretary of state take office, they will discover that they face the same choices that the current administration did. They can increase Putin’s agony using economic, political, and military tools and make sure he stops fighting. Or they can let him win, quickly or slowly. But a Russian victory will not make Europe safer or the U.S. stronger. Instead, the costs will grow higher: A massive refugee crisis, an arms race, and possibly a new round of nuclear proliferation could follow as European and Asian democracies assess the new level of danger from the autocratic world. An invasion of Taiwan becomes more likely. An invasion of a NATO state becomes thinkable.

[Karl Marlantes and Elliot Ackerman: The abandonment of Ukraine]

In the final two months of his presidency, Joe Biden, together with Ukraine’s European allies, will have one last chance to push Russia hard, to respond to the extraordinary Russian–North Korean escalation, and to stabilize the Ukrainian front line. This is Biden’s last chance to allow Ukraine to carry out long-range strikes against targets inside Russia. Although the Russians can strike any target, military or civilian, anywhere in Ukraine and at any time, the Ukrainians have been limited to their own drones. They have had some startling successes—their drone operations are now the world’s most sophisticated—including hitting military factories all over Russia, and several targets in Moscow this week. But to stop attacks on their cities and to prevent the Russian military from moving troops and equipment toward their borders, they need to be able to use missiles to hit air bases and logistical hubs inside Russia too.

Even more important is the question of money. Biden must press upon the Europeans, as a matter of urgency, the need to transfer frozen Russian assets to Kyiv—not just the interest but the capital. This money—more than $300 billion—can be used to purchase weapons, rebuild the country, and keep the economy going for many months. Most of this money is in European institutions whose leaders have delayed making final decisions about it for fear that Russia will retaliate against European companies, especially French and German companies that still have assets in Russia. But now time is running short: Perhaps the Trump administration will preserve sanctions on Russia, but perhaps it will not.

Biden’s team says it will expedite the delivery of the remaining weapons and resources that Congress has already designated for Ukraine. The goals should be to stabilize the front lines and prevent a collapse in Ukrainian morale; to provide long-term support, including spare parts so that repairs and maintenance of existing weapons systems can continue; and, most of all, to hit the North Korean troops in Kursk. It’s very important that the North Korean leadership perceives this escapade as a catastrophic failure, and as quickly as possible, so that more troops aren’t sent in the future.

After that? The choices, and the stakes, remain very similar to what they were in February 2022. Either we inflict enough economic pressure and military pain to convince Russia that the war can never be won, or we deal with the far more ominous, and far more expensive, consequences of Ukraine’s loss. Biden has a few more weeks to make a difference. It will then be up to Trump to decide whether he will help Ukraine to succeed and to survive, or whether he will push Ukraine to fail, along with the broader democratic world.

Europeans should pay Donald Trump the compliment of believing what he does and says, not what they desperately want to hear. He has clearly indicated that he wants the United States out of the Ukraine war as soon as possible. Both the president-elect and his most important supporter, Elon Musk, have reportedly been in frequent contact with Russian President Vladimir Putin. Vice President–elect J. D. Vance has outlined a “peace” deal with Ukraine that would serve Russian interests. American aid to Ukraine, which has been vital to the beleaguered country’s ability to resist Russia’s ongoing invasion, could stop not long after Trump is inaugurated. European nations must accept this reality and make their own plans—not just to support Ukraine in its existential fight but also to protect their own security as America’s global role shrinks.

Perhaps the best that Ukraine and its supporters can hope for is that Trump doesn’t walk away from NATO and allows European states to purchase U.S. weapons for Ukraine. This minimal position might represent a victory of sorts for Europeans who believe in democracy and the transatlantic alliance—but it would still signal a historical break. The United States will likely stop leading the global opposition to Russian aggression, and perhaps stop caring about the results of the largest war in Europe since 1945. Indeed, the president of the United States will be closer personally to the head of Europe’s largest dictatorship than to any of the continent’s democratically elected leaders.

[Anne Applebaum: The case against pessimism]

Those leaders should have started preparing for another Trump presidency long ago. They had been warned. But for the past year many Europeans have been surviving on hope. Surely the American people won’t vote for Trump, particularly after the January 6 insurrection. The prudent assumption now is that the U.S. will no longer guarantee Europe’s security from Russia and other threats. Leaders should envisage a world where NATO no longer exists—or where the United States is no longer the leading force in the alliance.

In some ways, this is more scary psychologically than in practice. Europe—which is to say, the democratic countries enmeshed in institutions such as NATO and the European Union—has the economic and technological resources to underwrite a serious defense effort. It has a large and educated enough population to staff modern armed forces. It also has some strong and growing military capabilities. For instance, European states either have received or will receive in the coming years as many as 600 F-35 fighters—the most advanced and capable aircraft in the world. Such a force could dominate the skies against a clearly inferior Russian opponent.

Yet Europe also has many weaknesses. It has developed a shockingly large number of military-hardware systems but then only builds a small number of each. This boutique way of addressing military capability has been exacerbated by a weakness in investing in logistics and a limited ability to produce supplies and equipment quickly and reliably enough to sustain a war effort.

Russia’s full-scale invasion of Ukraine in early 2022 prompted a lot of dramatic talk. The continent had supposedly reached a turning point—a Zeitenwende, in the phrase of German Chancellor Olaf Scholz. But Europe has frittered away much of the past two and a half years, making the smallest and most incremental of changes even as a grotesque war raged to the east; even as Russian forces regularly attacked civilian targets; even as military technology, particularly relating to drone systems, raced forward. European defense spending has only crept up. Even now, a number of NATO states fail to meet the alliance’s agreed-upon target of spending at least 2 percent of their GDP on defense. The United States, even after a significant decline in defense spending after the War on Terror, spends 3.5 percent. Two percent—a standard set in 2014, when European states felt far more secure than they currently do—won’t cut it now.

[Read: I’ve watched America and Ukraine switch places]

Scaling up defense systems quickly will be difficult, but it is essential. In the meantime, the highest priority from the European perspective should be to keep Ukraine supplied and in the fight in case Trump pulls the plug on American military support for Kyiv. Europe can provide more ammunition and more ground-based air-defense equipment. It can give Ukraine long-range weapons, such as German-made Taurus cruise missiles.

Just as important, European democracies can work with Ukraine to upgrade and expand its drone capacity—and in doing so help establish that industry elsewhere in Europe. Europe and even the United States have much to learn from Ukraine about unmanned aerial vehicles. The innovation cycle in Ukraine is quick; major advances take mere months or even just weeks. In this dynamic environment, where homegrown Ukrainian technology looms so large, few Western systems are of much use if sent whole. What Ukraine needs is the ability to mass-produce the drone technology that its engineers develop, working with European partners. That will require specialized components and equipment—and Europe can help with that.

If the United States abandons Ukraine, European states can start taking steps that the Biden administration, in its excess of caution, did not allow. The four most powerful states in Europe today—the U.K., France, Germany, and Poland—could give Ukraine their blessing to attack any Russian military targets. After all, Russia is using its weapons—and those provided by its allies, such as Iran, to attack targets in Ukraine; the American refusal to let Ukraine use Western systems against military infrastructure in Russia itself makes no sense.

European countries could go still further, by openly deploying their forces at least to western Ukraine. They could take over air-defense responsibilities—shooting down Russian missiles and drones without directly killing Russian soldiers. European forces could also openly assist in training Ukrainian forces in Ukraine and assist with air defense and training. Moves like these will reassure the Ukrainian people that they are not alone if the U.S. withdraws—and that their future is in Europe.

To be sure, the continent suffers from a collective-action problem. French President Emmanuel Macron asked this week, “The question we, as Europeans, must ask ourselves, is: Are we ready to defend the interests of Europeans?” Detractors might ask why he was raising the issue only now. In Germany, Scholz’s government appears on the verge of collapse. Even if it survives, it likely lacks the boldness to move decisively to help Ukraine.

And yet the greatest obstacle is a mental one. After decades of expecting the United States to act wisely and forcefully in defense of the broader democratic world, Europe needs to start thinking and acting on its own and in its own interests. Trump’s return means that things previously inconceivable must be faced. And in Ukraine, a new Europe can be born.

Americans voted for change in this week’s presidential election, and in foreign policy, they’ll certainly get it. Donald Trump has shown disdain for the priorities and precedents that have traditionally guided Washington’s approach to the world. He speaks more fondly of America’s autocratic adversaries than of its democratic allies. He derides “globalism” as a liberal conspiracy against the American people. And he treats international agreements as little more than wastepaper.

At stake is not only the survival of Ukraine and the fate of Gaza, but the entire international system that forms the foundation of American global power. That system is built upon American military might, but more than that, it is rooted in relationships and ideals—nations with shared values coming together under U.S. leadership to deter authoritarian aggression and uphold democracy. The resulting world order may be badly flawed and prone to error, but it has also generally preserved global stability since the end of World War II.

Despite its endurance, this system is fragile. It is sustained by an American promise to hold firm to its commitments and ensure collective defense. Trump threatens that promise. His plan to impose high tariffs on all imports could disrupt the liberal economic order on which many American factories and farmers (and Trump’s billionaire buddies) rely. His apparent willingness to sacrifice Ukraine to Russian President Vladimir Putin in some misguided pursuit of peace will strain the Atlantic alliance and undermine security in Europe. By signaling that he won’t defend Taiwan from a Chinese invasion, he could undercut confidence in the United States throughout Asia and make a regional war more likely.

[From the December 2024 issue: My hope for Palestine]

The American global order could end. This would not be a matter of “American decline.” The U.S. economy will likely remain the world’s largest and most important for the foreseeable future. But if Washington breaks its promises, or even if its allies and enemies believe it has or will—or if it fails to uphold democracy and rule of law at home—the pillars of the American international system will collapse, and the United States will suffer an immeasurable loss of global influence and prestige.

The risk that this will happen has been gathering for some time. George W. Bush’s unilateralist War on Terror strained the international system. So did Trump’s disputes with NATO and other close allies during his first term. But world leaders could write off Washington’s wavering as temporary deviations from what has been a relatively consistent approach to foreign policy over decades. They understand the changeability of American politics. In four years, there will be another election and a new administration may restore Washington’s usual priorities.

With Trump’s reelection, however, the aberration has become the new normal. The American people have told the world that they no longer wish to support an American-led world order. They have chosen U.S. policy makers who promise to focus on the home front instead of on the troubles of ungrateful allies. Maybe they’ve concluded that the United States has expended too many lives and too much money on fruitless foreign adventures, such as those in Vietnam and Afghanistan. And maybe now America will reassess its priorities in light of new threats, most of all China, and the potential burden of meeting them.

The problem is that if the United States won’t lead the world, some other country will, and a number are already applying for the job. One is Putin’s Russia. Another is the China of Xi Jinping.

China began to assert its global leadership more aggressively during Trump’s first term and has worked ever harder to undermine the American system since—strengthening China’s ties with Russia and other authoritarian states, building a coalition to counterbalance the West, and promoting illiberal principles for a reformed world order. Trump seems to believe that he can keep China in check with his personal charm alone. When asked in a recent interview whether he would intervene militarily if Xi blockaded Taiwan, he responded, “I wouldn’t have to, because he respects me.”

That’s narcissism, not deterrence. More likely, Putin and Xi will take advantage of Trump’s disinterest. Once appeased in Ukraine, Putin may very well rebuild his army with the help of China, North Korea, and Iran, and then move on to his next victim—say, Georgia or Poland. Xi could be emboldened to invade Taiwan, or at least spark a crisis over the island to extract concessions from a U.S. president who has already suggested that he won’t fight.

[Read: The case for treating Trump like a normal president]

The result will be not merely a multipolar world. That’s inevitable, whatever Washington does. It will be a global order in which autocrats prey on smaller states that can no longer count on the support of the world’s superpower, regional rivalries erupt into conflict, economic nationalism subverts global trade, and new nuclear threats emerge. This world will not be safe for American democracy or prosperity.

The fate of the world order and U.S. global power may seem of little consequence to Americans struggling to pay their bills. But a world hostile to U.S. interests will constrain American companies, roil international energy markets, and endanger jobs and economic growth. Americans could confront bigger wars that require greater sacrifices (as in 1941).

Perhaps Trump will surprise everyone by pondering his legacy and choosing not to pursue the course he has signaled. But that seems unlikely. His messaging on his foreign-policy priorities has been too consistent for too long. Over the next four years, Americans will have to decide whether they still want the United States to be a great power, and if so, what kind of great power they wish it to be. Americans wanted change. The world may pay the price.

There is anxiety among European leaders over trade, the future of NATO, and Russia's war in Ukraine.

The Middle East, China, Ukraine, NATO and economic policy are key areas of concern.
