Seyed M. Marandi: Threat of Seizing Kharg Island & the Use of Nuclear Weapons (Transcript)

Editor’s Notes: In this interview, Glenn Diesen sits down with Professor Seyed M. Marandi, a former adviser to Iran’s nuclear negotiation team, to explore the rapidly escalating conflict between Iran and the U.S.-Israeli coalition. The discussion analyzes the severe geopolitical and economic fallout that would follow a seizure of Kharg Island or the closure of the Strait of Hormuz, both of which are critical to global energy stability. Marandi details Iran’s defensive strategy, the potential for retaliation against regional U.S. bases, and addresses the alarming discourse regarding the possible use of nuclear weapons. Overall, this deep dive provides a critical perspective on the high stakes of the current “long war” and the miscalculations that could lead to a global economic collapse. (March 12, 2026)

Introduction

GLENN DIESEN: Welcome back. We are joined again by Seyed Mohammad Marandi, a professor at Tehran University and a former advisor to Iran’s nuclear negotiation team. Thank you for coming back on. I know you must be quite busy there in Tehran.

It does appear that this will be a long war, and we’re also seeing a rush up the escalation ladder from the American side. There’s now growing talks about seizing Iran’s Kharg Island, which will reportedly handle somewhere between 80 to 90% of Iran’s oil shipments. If the Americans would go through with this, it appears to be, well, essentially the nuclear option in terms of trying to shut down the Iranian economy.

Which then begs the question, what do you think is the likely Iranian response if the US would go down this path? Because I’m guessing the theory response, otherwise they would have already either attacked it or attempted to seize it.

The Challenge of Seizing Kharg Island

SEYED M. MARANDI: Well, first of all, thank you very much. Sorry. Thank you very much for inviting me.

I think it’s quite clear that it would be a major problem just accessing the island because the United States would have to use the territory of these or fly over territory of the Arab family dictatorships in the Persian Gulf. And that would mean that Iran would have to retaliate. So if Iranian territory is occupied, then that takes the war towards a major escalation. And so these regimes would have to pay a very heavy price, far greater than what they are paying now.

But for the United States, it would be very difficult because the islands are well protected. And also Iranian assets on the shore would be there to support the islanders and the people on the island and the defense capabilities there. And it’s far away from the US Navy, and it is closer to the Iranian shore.

But most importantly, I think, is the futility of such an aggression. This aggressive move would not change the status of the Persian Gulf region. It would not change the situation in the Strait of Hormuz. Iran has shut the Strait of Hormuz, and therefore nothing can leave or enter the strait without Iran’s permission. The strait is not formally shut, but ships that want to pass through have to gain permission.

And so an aggressive act by the United States against an island, a territory of the Islamic Republic of Iran, would mean fierce combat. It would mean that the countries that were used to enable such an aggression would be severely punished. And we have to remember Kuwait, Saudi Arabia, the Emirates, Bahrain, Qatar. These are largely deserts. All they have is oil or gas. They don’t even have water. They have desalination plants. They’re completely vulnerable to Iranian retaliation.

And then again, as I said, it’s not going to change things. Let’s see if the Americans carry out such an operation and succeed in taking the island, hypothetically, it’s not going to change the global energy market for the better. It will make it worse because Iran’s retaliation will include the destruction of assets of these countries that are engaged in cooperating in the invasion of Iranian territory.

So that would mean long term damage because we have two issues here. One is that the Strait of Hormuz is more or less closed. So there is every day 20 million barrels of oil that are not reaching the global markets, and gas and fertilizer and everything else alongside that. So every day this is happening.

But if there’s war in the Persian Gulf, those installations will be destroyed. And that means that even if they open the Strait of Hormuz later on during or after some sort of agreement, there will be no oil, there will be no gas to transport and there will be no tankers to do the transporting.

So it would be a ridiculous move, logistically very difficult, if not almost impossible. And Iranian defenses of course would be taking force, destroying a lot of the US military capabilities. And it would be futile and it would actually be more than futile. It would be very detrimental because of the long term effects that it would have on the global markets.

Iran Mining the Strait of Hormuz?

GLENN DIESEN: What should we make though of the reports of Iran mining the Strait of Hormuz? Because this would also then prevent Iranian ships, I would assume to some extent, and as well as friendly nations’ ships to transit through the strait. Do you know anything about this operation?

SEYED M. MARANDI: Iran hasn’t mined the Strait of Hormuz or the Persian Gulf or the Indian Ocean. That is all non-part of the Iranian Navy which can be used in the time of war is in underground tunnels. They are speedboats, very powerful weapons that can be used for asymmetrical warfare. And Iran has published some footage of these tunnels. It’s sort of like the underground missile bases and the underground drone bases.

So you have speedboats both inside the Persian Gulf and outside in very large quantities with sea to surface missiles, sea to sea missiles that can destroy anything in the Persian Gulf region and outside of the Persian Gulf.
