John Mearsheimer: All-Out War in the Middle East & Trump’s War on Russia (Transcript)

Read the full transcript of political scientist John Mearsheimer’s interview on Greater Eurasia Podcast with host Glenn Diesen, July 15, 2026.

Editor’s Note: In this discussion, political scientist John Mearsheimer analyzes the escalating conflict in the Middle East and the shifting dynamics of the war in Ukraine. He argues that U.S. attempts to apply military and economic pressure against Iran and Russia have largely backfired, pushing these nations closer together and strengthening their resolve. Mearsheimer warns that Western leaders are neglecting fundamental principles of balance-of-power politics and nuclear deterrence, creating an increasingly dangerous environment as these regional conflicts intensify.

Introduction

GLENN DIESEN: Welcome back. We are joined today by Professor John Mearsheimer. It’s July 15th, 2026, and the topic of discussion is the war in Iran, which looks like it could become a regional war. So thank you for coming back on the program.

JOHN MEARSHEIMER: My pleasure as always, Glenn.

The Escalating Regional Conflict

GLENN DIESEN: So we see many things happening now. There’s an intense escalation, but it also appears that a lot of countries are now getting pulled into what could be a much, much wider war.

That is, well, Iran obviously is being bombed heavily by the United States. The US claims it has reimposed the naval blockade. The Iranians, of course, they’re retaliating, focusing especially then on Bahrain, Kuwait, Jordan. And Yemen joined the fight by striking Saudi Arabia. I think the Saudis are now mobilizing their troops. Also, Iran has now threatened to close down access to the Red Sea.

So it’s all getting very complicated. And I was wondering, how are you reading the situation? Because there’s a lot to sink your teeth into here.

JOHN MEARSHEIMER: I would just add that it appears that the Iranians have shut down Fujairah, their 2 important ports where oil is continuing to come out of the Middle East. One is Yanbu, which is the Saudi port on the Red Sea. And as you said, it looks like the Houthis may shut down the Red Sea. And that means that the Saudi oil going to Yanbu will not come out of the Red Sea.

And I would just note quickly that even if the Houthis don’t shut down the Bab el-Mandeb Strait, which is what closes off or potentially could close off the Red Sea, the Iranians could just attack Yanbu and shut down the flow of Saudi oil coming out of Yanbu. And as I said, they’ve already shut down the flow of oil coming out of Fujairah, and that’s the United Arab Emirates port on the Sea of Oman that is outside of the Strait of Hormuz.

So just very important to understand the UAE has been shipping probably about 1.7, 1.8 million barrels a day out of Fujairah, and that’s now been cut off. And it looks like the Saudi oil flow out of the Red Sea is likely to be cut off as well. So I just wanted to emphasize that those 2 places, Fujairah and Yanbu, really do matter. And both are now involved in the mix in a serious way.

I think to answer your question, Glenn, what’s happening here is that the war is escalating. More horizontally than vertically. You remember we had this big air war from February 28th to about April 8th, and then the air war ended and we transitioned on April 13th to the blockade. Well, these tit-for-tat attacks that are now taking place every day for probably about the past 8 days are not the same as the air war. They’re not that extensive.

And a lot of people are wondering whether we will vertically escalate and in effect go back to the air war that took place in the first 40 days of this conflict. That has not happened yet. But there is, and you described it very well, this horizontal escalation that is taking place. I don’t think that Jordan had been hit before 2 days ago, but it’s clear that the American base in Jordan is now being pounded. And of course, the Gulf states are being pounded.

And it looks like, you know, we see substantial horizontal escalation. Especially when you throw in the whole Yanbu and Fujairah scenarios that I described when I began talking. So this one is escalating for sure.

Theories of Victory: The American Perspective

GLENN DIESEN: Well, it’s always difficult to make predictions, but a good place of, or point of departure would be to assess the strategies of each side. That is, what are the objectives they aim to achieve? You know, what resources can they mobilize to achieve those objectives? How do you see the theory of what a victory might look like if you see it from the American perspective versus the Iranian? What is it that each side want to achieve here, and how can they actually achieve it?

JOHN MEARSHEIMER: Yeah, great question. Let’s just start with the Americans. I don’t believe that they have a theory of victory. I believe that President Trump is just flailing around.

If you go back to June 17th and the memorandum of understanding that was signed that day, that was basically a surrender document. It’s quite clear that the Iranians won on almost every point. If you look at the 14 articles, it looks clear to me that the Iranians won and we, the United States, lost.

So the question you then have to ask yourself is, given what’s happened since that memorandum was signed on June 17th, what have we done militarily to change the situation? Where is our new course of leverage coming from? I mean, we obviously didn’t have much coercive leverage before the signing of the June 17th Memorandum of Understanding. Otherwise, we wouldn’t have signed it because it was a surrender document. So you have to be able to make the argument that we now have some sort of military capability or economic capability to change the situation that existed on June 17th.
