The Foreign Affairs Interview

For most of the past few decades, North Korea was considered a top challenge for American foreign policy. In the past few years, however, it has mostly receded from attention—not because the U.S. approach to the problem succeeded but because it so completely failed. U.S. policy insisted that North Korea could never become a nuclear power, yet North Korea’s program has accelerated year by year, threatening not just American allies, ...

It is an understatement to say that the United States finds itself at a particularly fraught geopolitical juncture. The outcome of the war in Iran is still uncertain. The war in Ukraine continues with no end in sight. Add to that U.S.-Chinese competition, overlapping planetary crises, a highly erratic hegemon—the list could go on.

Such an unstable world presents a formidable test for policymakers in Washington and in every other ca...

The shockwaves of the ongoing war in Iran are being felt far and wide. The continued closure of the Strait of Hormuz has sparked a global energy crisis, one that could be accentuated by a U.S. naval blockade. Countries as disparate as Chile, South Korea, and Zambia have been forced to take extraordinary measures to deal with shortages and surging prices. But the war’s effects are not just material. Washington’s decision to attack I...

On Tuesday night, as the world held its collective breath, U.S. President Donald Trump announced a temporary cease-fire with Iran, just hours after warning that “a whole civilization will die” if the Iranian regime did not completely open the Strait of Hormuz. In exchange for a cessation of American and Israeli strikes, Iran has agreed to allow oil and other commodities to pass through the strait for two weeks and to stop its own a...

In 2024, when he was the director of the Central Intelligence Agency, William Burns wrote in an essay in Foreign Affairs about “the plastic moments that come along only a few times each century”—and argued that “the United States faces one of those rare moments today, as consequential as the dawn of the Cold War or the post-9/11 period.”

If that claim seemed bold at the time, events in the past couple of years have made it undeniab...

Just a few weeks after its opening salvos, the war in Iran is already going global. Iran has effectively closed the Strait of Hormuz, stranding oil tankers and causing energy prices to skyrocket. Donald Trump has asked European partners to help restore freedom of navigation. So far, they have largely rebuffed his requests for military assistance. But as the economic pain mounts, their resolve will surely be tested.

Europe’s difficu...

When the United States and Israel launched a joint war on Iran two weeks ago, U.S. President Donald Trump urged Iranians to rise up and rid themselves of their tyrannical rulers. He seemed buoyed by his success in swiftly removing Venezuelan dictator Nicolás Maduro in January. But the war in Iran has not progressed as smoothly as Trump might have liked. The authoritarian regime that runs the Islamic Republic remains firmly in place...

For about two weeks, U.S. and Israeli forces have bombarded Iran. They have targeted Iranian military and nuclear sites. They have slain Supreme Leader Ali Khamenei and other top Iranian officials. They have even sunk an Iranian vessel deep in the Indian Ocean. Iran has responded by hurling missiles and drones at targets in the Gulf, Israel, and elsewhere in what has become a surprisingly broad and sustained retaliation. U.S. Presi...

Over the weekend, U.S. and Israeli forces struck hundreds of sites across Iran and killed its supreme leader, Ayatollah Ali Khamenei. Large crowds of Iranians took to the streets, some to mourn, others to celebrate. The Islamic Republic has retaliated and launched strikes of its own across the Middle East. 

Much about the joint U.S.-Israeli operation remains unclear—was it meant to eliminate Iran’s nuclear capabilities after failed...

President Donald Trump wields American power like few leaders in U.S. history ever have. By imposing tariffs, threatening territorial conquest, and ordering military intervention, he deploys the United States’ strength to assert dominance over friends and foes alike.

Stephen Walt, a professor of international relations at Harvard, describes this uniquely Trumpian grand strategy as “predatory hegemony” in a new essay in Foreign Affa...

February 24 marks the fourth anniversary of Russia’s full-scale invasion of Ukraine. After Moscow’s initial onslaught, Ukrainian counteroffensives, and slow Russian gains since, the war has settled into a brutal pattern of attrition, adaptation, and endurance. Ukrainian cities are rationing electricity, as the Ukrainian military struggles to muster the manpower and munitions needed to gain a decisive edge. Meanwhile, the battlefiel...

A year into Donald Trump’s second term, the United States’ allies on both sides of the Atlantic seem to have recognized that they need a new strategy for this age of rupture, as Canadian Prime Minister Mark Carney called it. Trump’s grab for Greenland, his tit-for-tat tariffs on Canada, his approach in Ukraine—all have opened up rifts between the United States and many of its closest partners.

Chrystia Freeland has for years been o...

In 2024, there were more than 300 million migrants across the world—double the number there were in 1990. Many of those had been displaced by conflict or climate change; many were simply looking for jobs and a better life. But the national and multilateral systems designed to manage these flows have proved grossly inadequate, helping set off political convulsions not just in the United States and Europe but in countries around the ...

Canadian Prime Minister Mark Carney may have made headlines when he described a “rupture” in global order in a speech at Davos last month. But long before that, policymakers and analysts had already been grappling with this unsettled—and unsettling—era in global politics. And the challenge has of course been especially great for American allies facing a very different Washington.    President Alexander Stubb of Finland has become c...

One of the big surprises of Donald Trump’s second term has been the change in his approach to China. His first term marked the start of what seemed to be a hard-line consensus in Washington. But in the past year, the drivers of Trump’s policy have been much harder to decipher—including for Chinese policymakers. Beijing was prepared to respond forcefully to tough U.S. measures, as it has, most prominently, by wielding its control ov...

In the past year, Donald Trump has upended the global trading system and used American economic power like no president in recent memory. He’s imposed tariffs to force other countries to fall into line on commercial issues and geopolitical disputes—like this week’s threats against NATO partners over Greenland. He’s called into question the role of the dollar. And at home, he’s attacked the independence of the Federal Reserve and in...

At the end of December, protests erupted across Iran. The government has since cracked down hard with potentially thousands of Iranians killed. It now seems possible that the United States might intervene. Via social media, U.S. President Donald Trump has told Iranian protesters that “help is on the way.” We do not know yet what, if anything, Washington will do. But the repressive regime of Ayatollah Ali Khamenei is being pushed to...

It was just a few days ago that, after months of saber-rattling by the Trump administration, U.S. forces raided Venezuela and captured its leader, Nicolás Maduro. Already, Trump has suggested that the United States could “run” the country and has demanded a huge stake in Venezuela’s vast oil resources. Maduro, meanwhile, sits in a New York jail, awaiting his next court date in March.

But much remains unclear—about what happens in V...

The biggest questions in U.S. foreign policy today tend to be about China. Policymakers and analysts argue over the implications of China’s rise, the extent of its ambitions, the nature of its economic influence, and the meaning of its growing military strength. Underlying these arguments is a widespread sense that where Beijing once seemed likely to slot comfortably into a U.S.-led international order, it now poses a profound chal...
