Ten days into a war started by the United States and Israel, Iran has done something its enemies were quietly betting it could not do: name a new supreme leader. Mojtaba Khamenei, 56, a secretive cleric with deep ties to Iran's paramilitary Revolutionary Guard, was chosen by the 88-seat Assembly of Experts to succeed his father, Ayatollah Ali Khamenei, who was killed in the war's opening salvo alongside Mojtaba's own wife.

The selection is not just a political event. It is a strategic signal. The Islamic Republic, absorbing a punishing air campaign from the world's most powerful military, has not fractured. It has consolidated. The clerics chose continuity over compromise, and in doing so, told Washington and Jerusalem that the war is far from over. (AP, March 9, 2026)

Oil markets got the message instantly. Brent crude spiked to nearly $120 per barrel - the highest price since 2022 - before falling back toward $90 as traders bet on a diplomatic off-ramp that may not exist. Meanwhile, Iranian demonstrators poured into central Tehran chanting "Death to America" and "Death to Israel" in a show of loyalty to the new supreme leader that the state actively encouraged.

Mojtaba Khamenei has been a political presence in Iran for decades without most of the world knowing his name. That was by design. Born in 1969 in Mashhad - a holy city in northeastern Iran - he grew up watching his father agitate against Shah Mohammad Reza Pahlavi. The SAVAK, the shah's secret police, once broke into their home and beat the cleric. A young Mojtaba was woken up and lied to. His father refused to lie to him.

After the 1979 Islamic Revolution brought his family to power, Mojtaba Khamenei fought in the Iran-Iraq war with the Revolutionary Guard's Habib ibn Mazahir Battalion - a unit whose veterans went on to hold major intelligence positions within the IRGC, a career ladder that almost certainly benefited from the Khamenei family name.

When his father became supreme leader in 1989, Mojtaba stepped into a role with no official title but enormous unofficial reach. U.S. diplomatic cables published by WikiLeaks in the late 2000s began referring to him as "the power behind the robes." One 2008 cable described an allegation that Mojtaba actually tapped his own father's phone and served as his "principal gatekeeper," forming a personal power base that rivaled the office he ostensibly served.

"Mojtaba is, however, due to his skills, wealth, and unmatched alliances, reportedly seen by a number of regime insiders as a plausible candidate for shared leadership of Iran upon his father's demise, whether that demise is soon or years in the future." - U.S. Embassy cable, 2008, via WikiLeaks

The cable also noted his lack of theological qualifications - a notable gap for someone seeking to hold an office that is supposed to be among the highest religious authorities in Shia Islam. His age at the time was also flagged as a concern. Neither obstacle proved fatal.

The Treasury Department sanctioned Mojtaba Khamenei in 2019, during Trump's first term, for working to "advance his father's destabilizing regional ambitions and oppressive domestic objectives." That designation now looks almost like a preview. The man the United States tried to financially isolate seven years ago now commands Iran's nuclear arsenal, its missile forces, its paramilitary apparatus, and the state machinery of a country at war with the United States.

From "Lightweight" to Supreme Leader: Trump's Miscalculation

In the days before Mojtaba Khamenei was formally selected, Donald Trump did something few American presidents would do: he publicly opined on who Iran's next supreme leader should be and explicitly said Mojtaba was not acceptable.

"They are wasting their time. Khamenei's son is a lightweight. I have to be involved in the appointment. Khamenei's son is unacceptable to me. We want someone that will bring harmony and peace to Iran." - President Donald Trump, interview with Axios, March 2026

The statement was remarkable for its assumption: that an American president could credibly demand a role in selecting Iran's supreme leader mid-war. The Assembly of Experts, Iran's 88-seat clerical body tasked with selecting the paramount leader, proceeded to ignore Trump entirely and selected exactly the man he called a lightweight.

Iran scholars noted the irony: Trump's public rejection of Mojtaba Khamenei may have actually boosted his standing with hard-liners within the Assembly of Experts. When America says "not him," Iranian theocrats hear "him." The dynamic echoed Trump's first term, when his public pressure campaigns repeatedly produced the opposite of their intended effect within Iran's political system.

Secretary of State Marco Rubio, meanwhile, continued to define the war's objective in terms that pointedly avoid the word "regime change." Rubio said the United States is "well on our way" to achieving its goal, which he defined as eliminating Iran's ballistic missile stockpile and its capacity to produce and launch them. But as one senior official noted to AP on background, "eliminating missiles is not eliminating the theocracy. Those are two very different things."

What U.S. Intelligence Knew - and When

A classified assessment completed by the National Intelligence Council in February - weeks before the war began on February 28 - concluded that American military intervention was not likely to lead to regime change in Iran, even in a scenario where Iran's entire leadership was killed, according to two people familiar with the finding who spoke to AP on condition of anonymity. (AP, March 9, 2026)

The NIC assessment found that no powerful or unified opposition coalition was poised to take over Iran if the government collapsed. It further concluded that Iran's establishment would attempt to preserve continuity of power in exactly the scenario now playing out: the killing of the supreme leader.

The intelligence community was right. Within days of Ali Khamenei's death, the clerical establishment had already moved to name his son. The Islamic Republic's succession infrastructure - the Assembly of Experts, the Guardian Council, the IRGC - had not fractured. It had activated.

The NIC report details were reported separately by the Washington Post and New York Times. The Office of the Director of National Intelligence declined to comment and referred questions to the White House. Director Tulsi Gabbard, who fired the NIC's acting chairperson in 2025 after a different declassified memo contradicted administration talking points on Venezuela, has not addressed the Iran assessment publicly.

The gap between what intelligence agencies concluded and what the administration has said publicly about its objectives is significant. Defense Secretary Pete Hegseth has said the war is not aimed at regime change. Trump has repeatedly implied it is. The intelligence community, before the war began, said neither approach was likely to work.

The Strait of Hormuz and a Market in Chaos

The succession of Mojtaba Khamenei hit oil markets at a moment already stretched to breaking point. Iran has effectively closed the Strait of Hormuz - the narrow choke point through which approximately one-fifth of the world's oil supply normally passes - using a combination of drone strikes, missile attacks on tankers, and naval harassment.

The International Maritime Organization confirmed that attacks on merchant ships near the strait have killed at least seven mariners since the war began. Dozens of tankers have rerouted around the Cape of Good Hope, adding weeks to delivery times and billions in shipping costs. Several major energy companies have declared force majeure on supply contracts.

Brent crude's spike to nearly $120 before settling back toward $90 tells a story of a market that cannot decide whether to price in a short war or a long one. Trump's remarks to lawmakers at his golf club in Doral, Florida - that the conflict would be "a short-term excursion" - temporarily calmed futures traders. But Iran's foreign policy adviser, Kamal Kharazi, said something quite different.

"Iran is prepared for a long war. There is no room for diplomacy anymore unless economic pressure prompts other countries to intervene and stop the aggression of Americans and Israelis against Iran." - Kamal Kharazi, Iranian foreign policy adviser, to CNN, March 9, 2026

Trump pushed back on concerns about supply, writing on Truth Social that "there is not an oil shortage" and that shipments from Venezuela could offset the price spike. Energy analysts were skeptical. Venezuela's production, once sanctioned by the Trump administration itself, cannot realistically compensate for a Hormuz closure. The Gulf states, also facing Iranian drone and missile strikes, are operating under threat conditions that limit their own production increases.

The War Spreads: Turkey, Russia, and a Second Front

The naming of Iran's new supreme leader landed against a backdrop of a war that is no longer contained to the Iran-Israel-U.S. triangle. Turkey - a NATO member - reported Monday that its air defenses intercepted a ballistic missile that entered Turkish airspace. It was the second such intercept since the war began. Ankara has not publicly attributed the missile to Iran, but the trajectory and timing leave little ambiguity.

NATO Article 5 - collective defense - has not been formally triggered, and Turkey's government has been careful in its public statements. But the fact that an alliance member's territory is being struck by weapons fired in a war the United States initiated is a political problem with no clean answer. NATO Secretary General Jens Stoltenberg has called for de-escalation. Trump has not publicly responded to questions about the Turkish intercepts.

Russia's involvement is also deepening, though in a different direction. Kremlin foreign policy adviser Yuri Ushakov confirmed Monday that President Putin spoke with Trump by phone to discuss the war. Ushakov described the hourlong call as "frank and businesslike" and said Putin "voiced a few ideas regarding a quick political and diplomatic settlement" following conversations with Gulf leaders and Iranian President Masoud Pezeshkian.

Putin's active diplomacy is a departure from the Kremlin's initial silence on the war. Russia and Iran have deepened military ties substantially since 2022 - Iranian drones helped sustain Russia's campaign in Ukraine, and Russian technical assistance has supported aspects of Iran's defense industrial base. Putin now faces a strategic dilemma: a prolonged war that weakens Iran also weakens one of Russia's key military partners. But a diplomatic settlement brokered partly by Moscow would restore Russian relevance in the Middle East at a time when it has been largely sidelined.

Meanwhile, Israel is continuing strikes across Iran. The Israeli military said Monday it was conducting "a wide-scale wave of strikes" on Isfahan, Tehran, and southern Iran, targeting what it described as the drone headquarters of the Revolutionary Guard among dozens of infrastructure sites. Israel claims to have eliminated more than 1,900 Revolutionary Guard soldiers and commanders since the war began, a figure it provided without independent evidence.

Nuclear Inheritance: The Stakes Nobody Is Naming Out Loud

The formal succession of Mojtaba Khamenei transfers more than an office. The supreme leader controls Iran's nuclear program and - more pressingly - the country's stockpile of highly enriched uranium. As of the latest IAEA reports before the war began, Iran had accumulated enough highly enriched uranium for multiple nuclear devices, though it had not taken the final steps to weaponize.

Whether those final steps are now being considered is the central question that Washington and Jerusalem are not willing to state publicly. Secretary Rubio's stated war objective - destroying ballistic missile capacity - would not eliminate Iran's enriched uranium stockpile, which is stored in hardened underground facilities. The Natanz and Fordow enrichment sites, buried deep underground, have reportedly sustained some bomb damage but remain operational, according to open-source analysis of satellite imagery.

Mojtaba Khamenei now holds the authority to issue a decree that could change Iran's nuclear calculus entirely. His ideological profile - more hardline than his father, with deep IRGC ties and a wife murdered by an Israeli airstrike - makes such a decree harder to rule out than it might have been under a more pragmatic successor.

The irony of the situation is not lost on analysts who follow Iran's nuclear program: the war launched in part to eliminate Iran's nuclear threat has placed that threat in the hands of the most hardline cleric to hold power in the Islamic Republic's history.

The "Martyrdom Dividend" and Iran's Internal Politics

Within Iran's political system, the deaths of Ali Khamenei and Zahra Haddad Adel - Mojtaba's wife, from a family long embedded in the theocracy - created what analysts are calling a "martyrdom dividend." In the lexicon of the Islamic Republic, those killed fighting or suffering at the hands of enemies are elevated to near-sacred status. The elder Khamenei and Mojtaba's wife are now officially martyrs of the war against America and Israel.

This changes Mojtaba Khamenei's political standing in ways that pure power calculations cannot fully capture. The aging clerics of the Assembly of Experts - men who might once have hesitated to appoint a cleric with limited theological qualifications and no formal government experience - now see in him the son of a martyr, the bereaved husband of a martyr, and a man sanctioned by the United States. In a system that defines itself by its resistance to America, all three facts are assets.

Kamal Kharazi's television appearance on Monday, declaring no room for diplomacy, was a preview of how the new supreme leader's team intends to conduct itself. The reformist current within Iran - which briefly appeared energized during the mass protests that killed thousands earlier in 2026 - has gone quiet. The war has done what years of repression could not fully accomplish: silenced the internal opposition. Waving an American flag in Tehran right now is not just dangerous. It is impossible.

Thousands of Iranians poured into Imam Hossein Square in Tehran on Monday in a show of support for the new supreme leader. Some demonstrations may have been state-organized; others appeared to draw genuine emotional response from Iranians who see the war as an existential attack on their country regardless of their views of the government. "America and Israel: You've failed, and you will drown in the swamp you are stuck in," said one demonstrator, Abbas Ali Saeedipoor, in remarks carried by Iranian state media.

What Comes Next: Three Scenarios

The selection of Mojtaba Khamenei forecloses some possibilities and opens others. Here is how the coming weeks are likely to play out:

Scenario 1: Short war, contested victory. Trump's "short-term excursion" framing suggests the administration wants a face-saving exit that can be called a win. Russia's diplomatic outreach - and the temporary oil price relief it produced - suggests there may be an off-ramp being quietly engineered. Under this scenario, Iran agrees to some form of pause or limited inspection regime on its nuclear sites, the U.S. declares its missile-destruction objective partially achieved, and both sides step back from direct confrontation. Mojtaba Khamenei's government continues, damaged but intact. Probability: low but rising.

Scenario 2: Prolonged air campaign, insurgent response. The more likely trajectory, given Kharazi's statements and Mojtaba Khamenei's profile, is a war that grinds on for months. The IRGC shifts to asymmetric tactics - proxies in Iraq, Yemen, Lebanon, and possibly Central Asia - while Iran continues missile and drone exchanges with Israel. Oil stays above $90. Global shipping remains disrupted. The American domestic political cost of a multi-month war without a clear victory definition begins to show.

Scenario 3: Nuclear escalation. The least likely but most consequential scenario. If Iranian military losses mount to a point where the new supreme leader concludes the theocracy cannot survive conventional war, the calculus around Iran's enriched uranium changes. This is the scenario that has kept three American presidents - including Trump in his first term - from pulling the trigger on military action for years. The question now is whether the bomb-first approach has made this scenario more or less likely. The intelligence community's pre-war assessment suggested more.

The war is entering its second week with a new supreme leader in Tehran, oil prices still elevated, a closed Strait, and an intelligence assessment that said this exact outcome - an entrenched, unified Iran with hardline leadership - was the probable result of military intervention. The question being whispered in Washington is no longer whether the war can be won quickly. It is whether it can be ended without defining what winning means.
