Transcript: Theodore Postol Interview: Evidence of Patriot PAC-3’s Near-Zero Interception Rate

The following is the full transcript of Professor Theodore Postol’s interview on Greater Eurasia Podcast, July 12, 2026.

Editor’s Note: In this insightful interview, Professor Theodore Postol of MIT joins Glenn Diesen to challenge the widely held narrative regarding the efficacy of the Patriot PAC-3 missile defense system. Drawing on decades of technical analysis and empirical video evidence, Postol argues that these interceptors—and other systems like the Iron Dome—have a near-zero success rate against modern ballistic missiles, despite their high costs and public claims of performance. The conversation serves as a critical examination of the current military landscape, warning that over-reliance on these systems could lead to catastrophic consequences in the face of evolving threats from conventional and potentially nuclear-armed ballistic missiles.

Introduction

GLENN DIESEN: Welcome back. We are joined today by Professor Theodore Postol, professor of science, technology, and national security at MIT. He’s an expert in nuclear delivery systems, missiles, and missile defense. And he has also worked as a former advisor to the Pentagon. So thank you for coming back on the program. It’s great to see you again.

THEODORE POSTOL: Oh, it’s my great pleasure, as always, here. Go ahead. Sorry.

The Patriot PAC-3 and Its Effectiveness

GLENN DIESEN: Yeah, no, I wanted to ask you today about the Patriot PAC-3 interceptors, because you have probably been the leading voice in discussing how ineffective they have been. And indeed, you know, you can argue that the inefficiency of this has a huge cost for the United States as well. That is, you know, he wants to sell these weapons as well, but you know, delusion also has a high price.

So I was wondering what you can say about them, because of course they are an important component of the US alliance system. They were used now and are still used extensively in the war against Iran. And Trump himself approved now at the NATO summit for Ukraine to get licensing rights to produce Patriots. So it is quite an important topic. So yes, please feel free to unpack your argument.

THEODORE POSTOL: Well, let me just slightly expand on the points you were making. We hope it won’t occur, but Europe is talking about war with Russia, which I think is delusionary, but that’s another discussion. But I think it’s extremely important that the European military and the political leaders understand that there can be no defense from Patriot, the Patriot PAC-3s against Russian ballistic missiles.

So this is an important finding if you believe that these systems can play a role in future wars. It’s also problematic with regard to the beginning or opening, reopening of hostilities in the Southwest Asia War because whether or not you have Patriots, it turns out you won’t be able to defend against ballistic missiles with them either. In addition, there are vast expenditures in the future for additional Patriots that people are now contemplating, particularly the US government, and of course governments that purchase Patriot with the support of the US government.

And if these systems don’t provide any real defensive capability, this is an important matter for the military planning as well as the political leadership to understand. So this is not a minor issue, although it’s a technical detail. It is a technical detail, but it is quite important.

Déjà Vu: The Gulf War of 1991

THEODORE POSTOL: We’ve had this debate before. My joke with my friends is, for me, this is déjà vu all over again. Because if I just show you a slide or two here, if we look at past experience, my colleague George Lewis and I published an article in 1993 after the Gulf War of 1991. And in that article, we laid out the technology and the scientific foundation for determining whether or not Patriot in the Gulf War of 1991 actually worked.

Now, the history of this has been rewritten. I discovered this when I was in Poland giving a talk that there’s a whole new history of what actually happened. The new history is that they initially thought it worked, then they realized it didn’t work because of a congressional investigation. Of course, the congressional investigation occurred because of this particular article and the work of Lewis and Postol, so it wasn’t just happened to occur, it was because of our work.

And we were attacked ferociously to the point that quite frankly I thought, among other people, that my life was under threat. This was not a minor attack on the part of Raytheon and they went after me through MIT administration. This was a very unpleasant experience and taught me that all this talk about scholarly freedom, certainly at MIT, is not the case.

The American Physical Society’s Findings

THEODORE POSTOL: But in any case, 6 years later, though it took a long time, 6 years later, there was a study produced, published in the same refereed journal by a panel of the American Physical Society. And what this article said right in the abstract was that they found an absolute contradiction between the Army’s claims about Patriot’s performance in the Gulf War and for all the engagements we scored in our video data.

So we found the claims initially — President George H.W. Bush was misled. We later found out he believed that 41 out of 42 Patriot engagements had been successful. So this was like a 96% intercept rate. His Secretary of Defense at the time, Dick Cheney, also believed that this was the case.

Now, this is in some sense a piece of history, and you might argue it has no significance, but it’s kind of a replay of what we’re seeing among the European leadership and other leaderships who seem to believe without evidence that this system has capability. And it’s clear that they’re relying on this, or they have been relying on this. And in fact, the system has not been working since the Gulf War of 1991.

So at some level, you could argue it doesn’t matter because it’s never been working.
