Steven Jermy: Iran War Endgame & the Global Fallout (Transcript)

Editor’s Notes: In this insightful interview, Glenn Diesen sits down with retired Royal Navy Commodore Steven Jermy to analyze the complexities of the current conflict involving Iran, Israel, and the United States. They delve into the strategic failures of past Western interventions and discuss why the goal of regime change through air power alone may be destined for failure. The conversation also explores the broader geopolitical stakes, including the impact on global energy supplies and the shifting power dynamics between the U.S., Russia, and China. This deep dive provides a critical assessment of the potential for a strategic reversal and what it means for the future of global stability. (Mar 1, 2026)  

TRANSCRIPT:

Introduction

GLENN DIESEN: Welcome back. Today we are joined by retired Royal Navy Commodore Steven Jermy, who commanded warships in the 5th Destroyer Squadron and Britain’s Fleet Air Arm. He was also a strategy director in the British Embassy in Afghanistan. So thank you for coming back on. It’s good to see you again.

STEVEN JERMY: Yeah, good to be back, Glenn. They say may you live in interesting times. And we certainly do.

Assessing the War Against Iran

GLENN DIESEN: Yeah. Well, the last two days especially been interesting. The war against Iran, it’s very different than anything we have seen or done over the past 30 years. It seems, I mean, in terms of a war, there doesn’t seem to be a clear strategy. The planning appears to have been insufficient in terms of preparing for a smaller war, there seems to be little capacity to defend all the assets in the region. There’s no escalation dominance, it seems, and too many things that could go wrong and now seems to be going wrong.

I simply put, I don’t really understand the decision of going to war, given that so many of the variables here were uncertain. But you are a Royal Navy Commodore. What are you looking at to assess whether the Americans and Israelis will be defeated here or if they will win?

STEVEN JERMY: I’m looking at the analysis from two points of view, Glenn. The first is at the political military level and in the shorter term. So how do I think the campaign will actually play out? And then the second is at what I call the grand strategic level. And what does this look like in the medium to the longer term? And it’s quite subtle at that second level. But we might want to perhaps approach the question at those two levels.

Looking first at the political military level, I think a good introduction to this is the work of two people who you will know as well as I probably. The first is General von Clausewitz, who said that before entering into a war you really need to understand the nature of the war. And I’ve got a strong sense that the Americans don’t understand the nature of the war.

The other thing is General André Beaufre, who’s a French General, who I’m a fan of, who said that in war the loser deserves to lose because his defeat will be a consequence of failures of thinking either before or during the war. And I’m worried that failures of thinking before the war are likely to lead to consequences that not only result in a potential defeat for the forces of Israel and America, but also longer term consequences which run against the whole interest of the west and indeed the global economy. So that’s the way I’ve been thinking about it.

Strategic Objectives: Regime Change Through Air Power

In terms of the strategic objectives, I think at least we can be clear. And I think one thing I would say — I would just challenge you on one thing which you said, that this isn’t like the last wars. I think it is like Afghanistan, Iraq, Libya and then Syria, inasmuch as there isn’t a strategy. So again, we seem to be in the same situation where we don’t seem to have thought it through strategically.

I think that there does seem to be a strategy here from Israel and America’s point of view, which is to achieve regime change through air power. Now, that’s a big deal, achieving regime change through air power, not least of all because I can’t remember when it was last done or if indeed it has ever been done, because regime change — you really need to have something substantial. You need substantial forces on the ground, which of course, neither Israel nor the United States want to commit to.

So I think at least we do understand the approach that is being taken. I think it’s really important as well to be clear on that regime change objective, because on that falls the success or failure of the campaign. And if regime change isn’t achieved, then it would seem to mean that from Israel and the United States’ point of view, this will be a failure.

I think from Iran’s point of view, the objective to me seems to be to survive, because if indeed they can survive — and not necessarily, I don’t think they would ever expect to defeat Israel and the United States objectively — but if they can survive and do significant damage, and I think that their damage is starting to be done, then it will be a victory for them.

So survival, really, a bit like it has been for Hamas and Hezbollah — if for them it’s about not being defeated, rather than winning, and not being defeated for the Iranians, I think it’s a win. So I think that’s the way I’m starting to think about it, and then thinking about the campaign as well, which we could talk about. But is that your sense as well about what the overall objectives and strategy looks like?

Lessons from Past Wars: Afghanistan, Iraq, Libya, Syria

GLENN DIESEN: Yes, I think so. I think the US and Israelis probably planned for a quick war where they knock out the leadership and then the assumption will be that the whole thing would fall apart.
