Transcript: Tucker Carlson Interviews Harvard Professor Stephen M. Walt

Read the full transcript of Harvard professor Stephen M. Walt’s interview on The Tucker Carlson Show, August 24, 2026.

EDITOR’S NOTE: In this interview, Tucker Carlson sits down with Harvard professor and international relations expert Stephen M. Walt to examine the escalating risks in a post-war world shaped by conflicts with Iran and Russia. Walt, a longtime critic of U.S. interventionism and author of The Hell of Good Intentions, analyzes the forces driving America’s involvement in the Middle East, the rise of China, the potential for nuclear escalation, and the broader challenges to global stability and American democracy.

Opening

TUCKER CARLSON (00:00:04 – 00:00:05): First of all, thanks so much for doing this.

STEPHEN M. WALT (00:00:06 – 00:00:06): Nice to be here.

A More Dangerous World Ahead

TUCKER CARLSON (00:00:06 – 00:00:18): So let’s start at the end, the anticipated end, when and if the United States resolves its role in these 2 wars against Russia and against Iran. What does the world look like, do you think?

STEPHEN M. WALT (00:00:18 – 00:00:25): I think it looks like a substantially more dangerous world actually than we’ve seen for, say, most of my—

TUCKER CARLSON (00:00:25 – 00:00:26): After the wars?

STEPHEN M. WALT (00:00:26 – 00:02:58): Yeah, after the wars.

Well, it’s going to leave the world in a, I think, a more precarious condition and for sort of larger, more enduring reasons than just these conflicts. I mean, the relationship with Russia is not going to improve for a while, even if the war formally comes to an end. There’s lots of suspiciousness on both sides now, so that’s going to be a problem. China is going to continue to improve its military power. It’s going to continue to grow economically. It’s going to continue to challenge the United States and others for influence around the world. So that’s going to be a source of tension.

We have, I think, in the world today, you’re seeing other powers, lesser powers being more active and not always constructively. Think of the role that the UAE has played in the civil war in Sudan. So they’re involved in fueling conflicts in a variety of other places. So you’re going to see a tripolar world, Russia, China, the United States as the 3 main powers with some unresolved tensions among them continued, I think, concerns about what’s going on in Asia and what China’s ambitions might be there. And in a situation where no one really trusts America’s judgment anymore. And that’s, I think, an artifact of the war, especially the war in Iran.

Let me point to one other thing that I think people sometimes forget about, and that’s that we’ve seen, I think, a pretty dramatic erosion in the normative environment surrounding the use of force. And I’m a good realist, so I don’t think norms in international law are everything, but they’re not irrelevant. So one of the things we’ve seen is essentially a collapse of the norm against assassination. For a long time in world history, governments didn’t try to assassinate each other. Leaders of other countries didn’t try and kill each other in conflicts. This was a common practice 500 years ago, and it gradually fell from favor and a norm emerged against it. You can understand why. It was in everybody’s self-interest if you were a king, if you were a prime minister, not to be trying to kill each other. Moreover, great powers liked this norm because it meant that conflicts would be decided on the battlefield where they had all the soldiers and all the wealth and could win. Assassination is a tool of weaker powers.

TUCKER CARLSON (00:02:58 – 00:03:00): Right. It’s asymmetrical. Of course.

STEPHEN M. WALT (00:03:00 – 00:03:32): Right. And beginning at the end of World War II, when the Allies began to hold leaders accountable, Nuremberg Trials, the Tokyo War Crimes Trials, this idea that what you did as a statesman was sort of separate began to erode. Once that began to erode, then going after a leader, going after Muammar Gaddafi, going after Saddam Hussein begins to look morally preferable. Why not just take out this troublesome leader as opposed to fighting?

TUCKER CARLSON (00:03:32 – 00:03:33): Spare the population.

STEPHEN M. WALT (00:03:33 – 00:04:53): Yeah, spare the population. You could make this argument. Of course, this is a very dangerous road to go down because now it’s becoming a much more common practice. Look at what the United States and Israel do at the beginning of the Iran War. They take out all of Iran’s senior leaders. There’s at least 2 problems here. First of all, you don’t know who’s going to replace them. And of course, we’re now having trouble with a more hardline faction in Iran. It also erodes any possibility of trust. I mean, how can you sit down and negotiate a agreement with a regime that has killed your senior leaders and might do something again subsequently. And then finally, as that norm begins to erode, others are going to use it too. Others will start using similar tactics, and leaders, including American presidents, are going to have to worry much more about this than they did necessarily in the past.

All right, you put all of those things together, continued great power competition, eroding norms against the use of violence in a variety of different ways. I think you end up with a much more dangerous world. And I think unfortunately the world agrees with that. Because if you look at the last 20 years or so, in constant dollars, defense expenditures have basically doubled in the world over the last 20 years because—

TUCKER CARLSON (00:04:53 – 00:04:54): Not just in the US.

STEPHEN M. WALT (00:04:54 – 00:05:10): Not just in the United States. You see this happening in Asia. You see this happening in Europe now. Belatedly, but finally happening.
