In the four years since U.S. President Joe Biden took office, the geopolitical landscape has radically changed. Russia’s invasion of Ukraine brought war back to Europe. Hamas’s October 7 assault on Israel sparked a widening conflict in an already chaotic Middle East. And Chinese aggression in the Taiwan Strait has refocused attention on the Indo-Pacific as a possible theater of combat.

Through it all, Secretary of State Antony Blinken has been at the helm of U.S. foreign policy: shuttling between capitals, negotiating with allies and adversaries, and helping shape a vision for American engagement with the world—a vision he laid out in a recent essay for Foreign Affairs.

Now, on the eve of Donald Trump’s return to office, Blinken reflects on the geopolitical challenges facing the United States today—and offers lessons from his own tenure for American foreign policy going forward.

Over the last few years, the world has seen the outbreak of a kind of war that had long seemed like a thing of the past. There was Russia’s invasion of Ukraine; a Gaza war that threatened to turn into a full Middle Eastern war, and in many ways did; growing dangers in the Taiwan Strait or South China Sea; and tremendously damaging fighting in places like Sudan that get much less global attention.

Mara Karlin, a scholar of war as well as a veteran policymaker, served as the top U.S. Defense Department official overseeing strategy as these conflicts started or escalated. She is currently Professor of Practice at the Johns Hopkins University School of Advanced International Studies and a Visiting Fellow at the Brookings Institution, and the author of several books including The Inheritance: America’s Military After Two Decades of War. She argues in an essay in Foreign Affairs that the world is seeing a return of total war—of conflicts that are more comprehensive and complex than ever before.

Karlin joins Editor Dan Kurtz-Phelan to discuss how fighting in Ukraine and the Middle East is reshaping our understanding of modern war, and what this means for U.S. military strategy—especially in the face of growing tensions with China.

Donald Trump’s victory in the 2024 U.S. presidential election comes at a moment of turbulence for global democracy. It’s been a year marked by almost universal backlash against incumbent leaders by voters apparently eager to express their anger with the status quo—and also an era when liberalism has been in retreat, if not in crisis.

Francis Fukuyama, a political scientist at Stanford University, has done as much as anyone to elucidate the currents shaping and reshaping global politics. He wrote The End of History and the Last Man, a seminal work of post–Cold War political theory, more than three decades ago. And in the years since, he has written a series of influential essays for Foreign Affairs and other publications.

He joins Editor Dan Kurtz-Phelan to consider what Trump’s return to the presidency means for liberal democracy—and whether its future, in the United States and around the world, is truly at stake.
