Transcript: Will Trump’s Naval Blockade of the Strait of Hormuz Work? w/ Mearsheimer vs Landis

Editor’s Notes: In this episode, Tom Switzer hosts renowned political scientists John Mearsheimer and Joshua Landis to analyze the potential impact of President Trump’s naval blockade of the Strait of Hormuz following failed peace talks in Islamabad. Mearsheimer argues that the blockade is a “colossal blunder” that threatens to drive the global economy off a cliff while failing to break Iranian nationalism. Landis provides historical context on the U.S.-Israel strategy toward Iran and highlights how the resulting domestic inflation and high interest rates are damaging Trump’s standing with his own base. The panel also explores the shifting power dynamics in the Middle East, including the unexpected resilience of Hezbollah and the looming threat of a broader conflict involving Turkey and China.

Introduction

TOM SWITZER: Hello and welcome. I’m Tom Switzer. Always great to have your company. Now, today’s guests: Joshua Landis from the University of Oklahoma. Hi there, Josh.

JOSHUA LANDIS: Pleasure being here back again.

TOM SWITZER: Indeed. And John Mearsheimer, professor of political science from the University of Chicago. Hi there, John.

JOHN MEARSHEIMER: Hello, Tom. Hello, Josh.

TOM SWITZER: Now, Iran has failed to meet the US demands for a peace settlement. This was in Islamabad. And in response, President Trump has announced a naval blockade of the Strait of Hormuz. Now, these are for the ships using Iranian ports. Now, so we’re all on the one page, let’s remember that since the war— this was February 28th— Tehran has denied passage to most oil and gas tankers, and now the regime will get the same treatment. This is the argument, John. Will the US blockade work?

Will the Naval Blockade Work?

JOHN MEARSHEIMER: No, it not only won’t work, it’s counterproductive. And let me tell you why.

First of all, you have to understand that the United States and Israel represent an existential threat to Iran. And Iran is a highly nationalistic and tough-minded country. And when a highly nationalistic and tough-minded country faces an existential threat, it can absorb an enormous amount of punishment. So the idea that we’re going to get the Iranians to throw up their hands and surrender is not a serious argument.

Now, there’s another whole dimension to this. Why have we allowed Iranian oil out into the global oil market? Why have we removed economic sanctions from Iranian oil? It’s because we need that Iranian oil in the global oil market to stop the global economy from going off a cliff. Well, if we prevent that Iranian oil from reaching global oil markets, this is just going to threaten to do serious damage to the global economy.

And then there’s one final point. I’d be willing to bet that shortly the Houthis and the Iranians are going to shut down the Red Sea, and you’re not only not going to get oil and gas coming out of the Persian Gulf and fertilizers as well, but you’re also not going to get those products coming out of the Red Sea, and that’s really going to throttle the world economy, and that’ll force the Trump administration to finally concede defeat to the Iranians.

The Wall Street Journal’s Case for the Blockade

TOM SWITZER: Well, John, the Wall Street Journal editorial page, which you and I read almost every day, even if we disagree with it, President Trump also reads the Wall Street Journal because he attacks their editorials on social media. Now, the Journal over the weekend urged the president to do precisely this, that the US would quarantine all the ships transiting with Iranian oil.

Now, your second point there, I think, needs elaboration because we’ve discussed this before, that even as the US attacked Tehran during the war since February 28th, it was undercutting itself by encouraging the Iranian oil exports, which you just made. The question the Wall Street Journal might put to you is why should Iran alone be exempt from the costs of its illegal actions in Hormuz, raking in revenue while it starves the rest of the world? John.

JOHN MEARSHEIMER: It’s very simple. To keep the global economy afloat. I mean, we weren’t doing this because we were being benevolent or we were privileging the Iranians over the Saudis or anything like that. We did it because it was in our national interest. We did it because we understand that this whole war, once we didn’t win a quick and decisive victory as the Wall Street Journal and President Trump thought we would do, is in a world of hurt. And this could get really serious. We could create a global depression. And to avoid that, we’re allowing the Iranians to sell oil.

And by the way, Tom, as you well know, this is why we’re allowing the Russians to sell oil in global markets. This is why we took sanctions off the Russians as well.

TOM SWITZER: But the Journal would say to you, for the naval blockade to work, they’d actually concede that Trump must be willing to accept energy market pain.

JOHN MEARSHEIMER: Well, we’ll see how much energy market pain he’s willing to accept because he’s not the only player in this game. Every other country on the planet is about to absorb even more pain than they’ve already absorbed. And the telephone is going to be ringing nonstop at the White House from leaders all over the world telling President Trump with no uncertain terms that he has to shut this foolish escapade down before he drives the international economy off a cliff.

TOM SWITZER: Again, the Journal would say Iran has an incentive to restore traffic in the Strait, as does China, by the way. Their tankers have been given priority. So why should China get leeway and not the rest of East Asia and Europe? That’s what the Journal would respond to you.

JOHN MEARSHEIMER: Well, the Journal can say that till they’re blue in the face, but the fact of the matter is, the Iranians are in the driver’s seat here, and the Iranians have no intention of surrendering.
