John Mearsheimer: “Iran Holds All the Cards” @Greater Eurasia (Transcript)

Editor’s Notes: In this compelling discussion, Glenn Diesen and Professor John Mearsheimer analyze the strategic challenges facing the United States following the outbreak of a protracted conflict with Iran. Mearsheimer argues that the U.S. has fallen into a “quagmire” after a failed attempt at a quick victory, leaving the administration without a clear exit strategy as Iran gains leverage over global oil markets. The conversation explores the potential for catastrophic economic consequences and the dangers of a foreign policy driven by personal advisors rather than institutional expertise. This interview provides a sobering look at how the current path of escalation could lead to a major geopolitical and economic defeat for the West. (March 27, 2026)

TRANSCRIPT:

Trump’s Foreign Policy: Early Optimism and Shifting Expectations

GLENN DIESEN: Welcome back. We are joined again by Professor John Mearsheimer. So thank you very much for coming on the program.

I was hoping today we can maybe first take a step back and look at the wider strategy of the United States under Trump, because I was quite optimistic about his re-election. That is, he seemed to be capable of breaking from narratives and ideologies which I think the political west followed blindly over the past decades. And this seemed to be a requirement to navigate or adjust at least to the new realities of the world, which was that the unipolar distribution of power was gone.

So he recognized the US couldn’t be everywhere. So he more or less suggested, we have to go to the Western Hemisphere and East Asia, which means we have to pivot out of the Middle East and Europe, and that meant ending the war with Russia. This trapped US resources in Europe, and it pushed the Russians towards China. And also in the Middle East, he was quite consistent on ending the forever war.

So overall, what I’m trying to say is, although he’s a man who’s not very civilized in his demeanor, what he said was a lot more rational than what I heard from other politicians. So that’s why I wanted to hear from you. What do you make of his direction now? What’s going to happen to the pivot to Asia and this wider strategy which we saw outlined in the national security strategy of December 25th?

From Optimism to Disillusionment: The Iran Trap

PROFESSOR JOHN MEARSHEIMER: I think, Glenn, the best evidence of what you’re talking about regarding how people like us thought about Trump initially in terms of foreign policy, and what people think now, is reflected in the lineup of people on Judging Freedom, Judge Napolitano’s show. And of course, both you and I are regulars on the judge’s show.

I think if you go back to the first, maybe six, seven months after President Trump was elected, virtually everybody who appeared on that show was quite optimistic that Trump would represent positive movement in terms of American foreign policy — that there would be no more forever wars, he wouldn’t start any new wars, period, and there would be much, much less emphasis on a militarized foreign policy. And I think most importantly at the time, I think we all thought that there was a reasonable chance he would shut down the Ukraine-Russia war. So there was a lot of optimism about him. And of course, a lot of the people on the show — the Americans — didn’t vote for Trump. Some did, but everybody, I think, was generally pretty enthusiastic about the direction that he was going to take the United States.

I think now, if you watch Judging Freedom, almost everybody on that show is — and I’m choosing my words carefully here — very critical of President Trump. He is seen to have blown it, to have missed a terrific opportunity to change the direction that American foreign policy was going in. And if anything, he’s on the old path.

I think the key issue today is the Iran war. And all I can say is it’s truly remarkable that he allowed himself to fall into this trap. This is much worse than Afghanistan, much worse than Iraq. I mean, if you think about the Iraq war in 2003, at least in the initial stages, George W. Bush could land on the aircraft carrier and effectively declare “mission accomplished,” which is another way of saying, “We won.” Trump can’t do that. It’s been clear almost from the beginning that this is a lost cause.

But more importantly, the potential for really serious damage here is enormous. And here we’re talking mainly about the international economy, but not only the international economy. So he’s entered a war that he can’t win, and one could argue is likely to have catastrophic consequences for the world — not just for him and his presidency.

So it’s really quite remarkable when you think about it, where he has ended up in quite a short period of time. He was put in office January 20th of 2025, and the war started against Iran on February 28th, 2026. That’s effectively 13 months after he’s in office. So he starts off looking like he has a winning strategy, but 13 months later, he’s jumped into a huge quagmire that he can’t get out of. Truly amazing.

Trump’s Demands and the Question of Iranian Capitulation

GLENN DIESEN: Well, regarding the optimism, though, I wouldn’t say that it was rooted in being naive, because if you look, he did have a first term, and unlike all his predecessors going back to World War II, he didn’t start any new war. So he seemed to follow through on his rhetoric. So that’s why this has come as a bit of a surprise — how his foreign policy in the second time around went down this path.

But how do you make sense of the demands he’s making now? Because you said he can’t really get out of this.
