MI6's Last Interview: A Junta in Tehran, a War That Bought It Time

It is the last interview Sir Alex Younger gave, and the verdict it delivers on Tehran is colder than almost anything that has come out of London since the war began. The former head of MI6, who died last month, told The Economist that the Islamic Republic is no longer a dictatorship so much as a military junta — that the Islamic Revolutionary Guard Corps has taken full control after the killing of Ali Khamenei, and that Mojtaba Khamenei, the son installed in his father's place, is a figurehead for men with guns. Nine in ten Iranians want change, Younger said. Roughly one in ten hold the weapons. That math, in his telling, is the whole story of the war.

None of that is small change. The killing of Ali Khamenei in the opening U.S.-Israeli strike shattered Iran's political order and set off a succession crisis inside the security state ⁶. Before the attacks, the CIA had assessed that if Khamenei died, hardline IRGC elements would be the ones to fill the vacuum ⁷. Six months on, that prediction looks less like foresight than description. Analysts say real power now sits with the Guard regardless of who sits in the supreme leader's chair ⁴. The Guard, reporting says, has seized control of state functions, sidelined President Masoud Pezeshkian, and routed decisions through a military council that even Iran's own foreign minister appears unable to reach ⁸.

The portrait Younger paints matches what is on the public record. Foreign Minister Abbas Araqchi said publicly that a six-person security committee ran the nuclear negotiations, and that he had never met Khamenei the younger — who has not been seen since being injured in the same strike that killed his father ³. A Eurasia Group special report dated July 19 noted what it called Mojtaba's "seemingly limited" role in decision-making ⁹. Younger's contention that the Guard's leadership is "no less ruthless but more corrupt" than the clerical regime it replaced is, in the available reporting, an inference rather than a documented finding — but it tracks the Hudson Institute's Zineb Riboua, who argues the Islamic Republic is weaker than it wants the world to believe ².

What the available sources do not corroborate is the specific texture of the interview itself. None of the ten web sources in the research file references The Economist's sit-down, Younger's death last month, or any of his verbatim lines. That does not mean the interview did not happen; it means a reader outside the magazine's pages cannot, from these sources alone, verify the quotes. What follows is what Younger, in the video and as The Economist presents it, is on the record as saying.

Younger acknowledged the uncomfortable thing out loud: Iran currently holds the upper hand in the war, and he regretted reaching that conclusion. The January 2026 uprising is still fresh in his telling, with up to 10,000 citizens killed by IRGC-sponsored militias — a figure that does not appear in the available web reporting and sits in the video as Younger's own characterization. The opposition, he said, simply cannot organize under a sustained air campaign. Citing polling he said showed 80 percent of Iranians opposed the theocratic regime, he warned that the roughly 10 percent with the guns are proving decisive. A leaked Iranian presidency report recorded what it called the highest public anger ever measured in any country, with nine in ten Iranians wanting change ¹⁰ — close to Younger's number, not identical, and measured by a different hand.

His most arresting assessment was the one he saved for last. The war, Younger argued, is giving the regime an extra lease on life — not because the strikes are weak, but because peace is what the opposition needs to organize. The most likely end state, he said, is "down but not out," analogous to Iraq between the Gulf Wars. The biggest threat to the regime is not another missile or another bunker-buster; it is the silence that comes when the bombing stops.

The interview's second half turned to operational questions Younger said Western planners are arguing over. Iran's ballistic missiles, he claimed, can now reach as far as Diego Garcia — a range of up to 4,000 kilometers — extending the threat to a base that has been, until this year, mostly a logistics waypoint. He warned that U.S. and Israeli objectives may begin to diverge as the war drags on, and that President Trump may escalate in order to de-escalate, with Kharg Island — the platform that handles roughly 90 percent of Iranian oil exports — a likely candidate for that kind of signal strike. None of those specific claims is independently corroborated in the research file. The 4,000-kilometer figure, the targeting calculus, and the warning about divergent U.S.-Israeli aims appear only in the video and in Younger's reported remarks.

What the sources do confirm is the underlying posture Younger is describing. Reuters and Al-Monitor both reported, in the weeks after Khamenei's killing, that the Revolutionary Guards had taken a wartime lead and were "ensuring a harder line" ¹¹. CBC framed the succession question as one in which the IRGC had become the dominant force in Iranian decision-making ⁵. Younger is not reporting from those articles; he is reading off the same picture they describe, and then saying the thing Western officials usually leave out loud — that the harder line is working.

There is a harder line underneath that, too. Younger said he shed no tears for Ali Khamenei, who was killed at the start of the conflict. That is a sentiment, not a fact, and it is one the sources do not address. But it is the line that explains why The Economist framed the interview the way it did. Younger spent three decades inside a service that does not, as a rule, write op-eds. He spent his last filmed hour writing one.

The interview ends where it begins, on a line Younger is reported as delivering almost flatly: the regime is in its death throes, but the war has bought it time. Read one way, that is a forecast of eventual collapse. Read the other way, it is a forecast of how long the collapse will take, and how many people will be alive to see it.
