HORIZONS: w/ John J. Mearsheimer – The Return of Great-Power Politics (Transcript)

Here is the full transcript of John J. Mearsheimer in conversation with Vuk Jeremić, January 9, 2026.

Brief Notes: In this authoritative interview for Horizons, renowned political scientist John J. Mearsheimer deconstructs the definitive return of great-power politics, arguing that the “unipolar moment” ended in 2017 with the emergence of Russia and China as peer competitors. Mearsheimer delivers a sharp critique of the Biden administration’s “irrational” strategy of driving Russia into the arms of China, while outlining President Trump’s 2026 efforts to rectify this blunder and pivot focus toward the primary threat: Beijing.

The conversation explores the fracturing of European security, the “Monroe Doctrine” limits on middle-power hedging, and the six dangerous flashpoints in Europe—from the Arctic to the Black Sea—that could ignite a hot war. From the strategic leverage of rare earth minerals to the rise of “bounded orders,” Mearsheimer provides a masterful, realist roadmap for navigating a world where security now permanently trumps prosperity.

Introduction

VUK JEREMIĆ: It is a rare privilege to introduce a scholar whose ideas have not only shaped academic debate, but have fundamentally influenced how policymakers, journalists, and citizens around the world understand power, conflict, and the tragic dynamics of international politics.

John J. Mearsheimer is one of the most influential political scientists of our time and unquestionably the leading voice of structural realism in international relations. For decades, Professor Mearsheimer has challenged comforting illusions about how the world works. He has insisted, often against prevailing wisdom, that great powers are driven not by goodwill or moral aspiration, but by fear, competition, and a relentless pursuit of security. His arguments have been provocative, controversial, and impossible to ignore.

He is the R. Wendell Harrison Distinguished Service Professor at the University of Chicago, where he has taught generations of students to think rigorously and often uncomfortably about global politics. His books, including The Tragedy of Great Power Politics, The Israel Lobby and US Foreign Policy, and The Great Delusion, are modern classics, translated into multiple languages and debated across continents.

What sets Professor Mearsheimer apart is not only the clarity and discipline of his thinking, but his intellectual courage. He has consistently spoken truths that others preferred not to hear, warning often well in advance of strategic miscalculations and their consequences. Whether one agrees with him or not, one cannot engage seriously with international affairs without engaging with his ideas.

Thank you very much, Professor John Mearsheimer. It’s a great privilege to have you as our guest again. Thank you, sir.

JOHN J. MEARSHEIMER: My pleasure to be here.

The Return of Great-Power Competition

VUK JEREMIĆ: Well, let’s start with the big picture. For decades, you warned that the post-Cold War holiday from history was a delusion and that great-power competition would return with vengeance. We now obviously survey a world defined by intense security competition in Europe, in Asia, in the Middle East.

How does the reality of this transition compare to your predictions? In other words, is this the normalcy you expected, or has the shift been even more decisive than you had anticipated?

JOHN J. MEARSHEIMER: Well, I think from roughly 1992, shortly after the Soviet Union disappeared, and of course, the Cold War had ended at that point in time, up until about 2017, when China and Russia emerged as great powers, we lived in the unipolar world. And by definition, you cannot have security competition in a unipolar world because there’s only one great power.

But eventually, I think everybody recognized that new great powers would appear and we’d leave unipolarity. My argument is that this happened in about 2017, when China and Russia came on the scene as great powers. So starting in about 2017 and up to the present, we moved into a multipolar world, and great-power competition was back on the table.

Now, hardly anybody anticipated that there would be trouble once we left unipolarity and moved to multipolarity. They thought that peaceful relations among the great powers was forever, and it didn’t matter if we left unipolarity. I, of course, disagreed with that completely.

And I thought that the rise of China and China becoming a great power would lead to all sorts of trouble in East Asia and there would be an intense security competition between the United States and China in that region. Most people thought that I was foolish, that this was a ridiculous argument. Sadly, I believe I’ve been proved correct there.

And with regard to Europe, I long argued that trying to expand NATO, especially into Ukraine, was a prescription for disaster. It would lead to trouble with Russia. And of course, this trouble started even before Russia became a great power once again. The conflict in Ukraine, you want to remember, broke out in 2014, which was during the unipolar moment. And in my argument, it wasn’t until about 2017 that Russia was a great power again.

But regardless, the point is that we now have this terrible conflict in Ukraine between the West on one side and Russia on the other side. And of course, Ukraine has allied with the West. And again there, most people thought that we could expand NATO eastward and get away with it, that it wouldn’t lead to conflict. And again, I’m sad to say that I was correct on that one as well.

Trump 2.0 and the Shift from Liberal Hegemony

VUK JEREMIĆ: Well, Washington appears to have fundamentally shifted its approach under Donald Trump 2.0. The ambition to remake the world in America’s image seems to have largely evaporated and is now replaced by a much sharper, much more transactional focus on national interest.

To what extent does this new strategy, if it is a strategy, actually align with the realism that you have long advocated versus simply being a retreat from global leadership, like some other scholars and analysts are openly lamenting?

JOHN J. MEARSHEIMER: Well, I know it’s commonplace for people to argue that this is a retreat from global leadership and that the United States is pursuing or moving toward an isolationist foreign policy. This is nonsense.
