Who Won the War? US and Israel vs Iran Explained

The US and Israel destroyed Iran's nuclear programme, killed Supreme Leader Khamenei and struck over 3,000 targets. Iran installed a new leader, kept its regime intact and forced oil above $119 a barrel. So who actually won? The answer depends entirely on what you think victory looks like.

The War Nobody Agrees Is Over

As of 11 March 2026, the 2026 Iran conflict is still active. There is no ceasefire. Iran has ruled out negotiations while attacks continue. Defence Secretary Hegseth says the enemy must be totally and decisively defeated. Trump says it will all be over very soon. Both cannot be right on the same timeline, and the gap between those two positions is where the question of who won currently lives.

What is clear is that the 2026 war is not the first confrontation between these adversaries. A previous Twelve-Day War was fought between Israel and Iran in June 2025, ending in a US and Qatar-mediated ceasefire on 24 June 2025. According to Wikipedia's account of that conflict, the ceasefire held in part due to Trump's continued direct intervention with Netanyahu, and both sides claimed victory while analysts judged Israel to have achieved its primary military objectives. The 2026 conflict is a direct continuation of the unresolved tensions that ceasefire left behind.

What the US and Israel Set Out to Do

The stated objectives of Operation Epic Fury were ambitious and wide-ranging. Israel's Foreign Minister Gideon Sa'ar said military action was urgently needed despite significant risks because delay would have allowed Iran to reach nuclear immunity and begin mass production of long-range ballistic missiles. Netanyahu said the goal was to remove the existential threat posed by the Iranian regime and create conditions for Iranians to take their destiny into their own hands. Trump, in his most aggressive framing, urged Iranians to rise up and told them the hour of your freedom is at hand.

Trump also signalled a more pragmatic fallback objective, telling the New York Times he was open to an outcome similar to Venezuela, where the regime remained in place but began cooperating with US demands. That framing acknowledged from early on that full regime change was not guaranteed, and that a coerced, compliant Iranian government might be an acceptable result. The distinction between those two objectives, regime removal versus regime compliance, would come to define the ambiguity in the war's outcome.

What the US and Israel Achieved

By the metrics of military destruction, the US-Israel campaign has been formidable. US CENTCOM struck more than 3,000 targets inside Iran over 10 days, with strikes recorded in at least 26 of Iran's 31 provinces. Tehran was the most heavily targeted location. Nuclear facilities, missile production sites, the IRGC Malek-Ashtar building, Iran's state broadcaster headquarters, the parliament building and key military command structures were all hit. Iran itself confirmed it had fired over 500 ballistic and naval missiles and almost 2,000 drones since 28 February, a rate of expenditure that analysts say significantly depleted its stockpiles.

The single most consequential military outcome was the killing of Supreme Leader Ali Khamenei in the opening strikes. His death removed the central figure of Iran's theocratic system, disrupted the chain of command, forced an emergency leadership transition, and created exactly the kind of political instability that both Washington and Tel Aviv had calculated could produce longer-term change. Israel's Defence Minister Israel Katz stated that the ceasefire would only hold as long as Iran refrained from reconstituting its ballistic missile or nuclear programmes, framing the military campaign as having achieved a durable constraint on Iran's capabilities rather than merely a temporary pause.

Who Gained What: A Side-by-Side Assessment

Iran's Regime Survived: What That Means

The single most important political fact of the conflict so far is that Iran's clerical establishment survived it. On 8 March 2026, senior clerics appointed Mojtaba Khamenei as Supreme Leader. The IRGC, parliamentary speaker Mohammad Bagher Ghalibaf, council chief Ali Larijani and President Masoud Pezeshkian all pledged allegiance. Trump had declared Mojtaba unacceptable. His installation meant the Islamic Republic had successfully reproduced itself at its highest level of authority despite the assassination of its supreme leader, the most direct attack on its leadership in its 47-year history.

Iran's intelligence services simultaneously reached out through a third country's intelligence service to the CIA, offering to discuss ceasefire terms. The New York Times, which reported this back-channel contact, noted it revealed the disarray at the top of Iran's leadership structure: even as Tehran publicly projected defiance, it was quietly trying to find a way out. Trump himself acknowledged the shrinking pool of potential Iranian interlocutors in a strikingly candid remark: "Most of the people we had in mind are dead," he said, adding, "Pretty soon we are not going to know anybody."

From First Strike to the Question of Who Won

What Analysts Say

Independent assessments of the conflict's outcome diverge sharply depending on the framework applied. Those who measure success by military destruction rate the US-Israel campaign as highly effective: 3,000 targets struck in 10 days, the supreme leader killed, nuclear infrastructure destroyed across 26 provinces and Iran's missile stockpile substantially depleted. By those metrics, Trump's claim that the operation was ahead of schedule is credible.

Those who measure success by political outcome reach a more complicated verdict. Al Jazeera's live coverage of the conflict documented how Iran's political establishment moved with striking speed to maintain continuity after Khamenei's death, suggesting the Islamic Republic's institutional resilience was higher than Washington had anticipated. Trita Parsi of the Quincy Institute noted that Netanyahu made a clear effort to weaken and possibly overthrow the Iranian establishment and was already looking for another opportunity if the ceasefire held. Bamo Nouri, writing for The Conversation, argued Netanyahu had been seeking an exit strategy from early in the conflict, wary of a long war of attrition Israel could not afford.

Frequently Asked Questions

What Comes Next?

The question of who won this war will ultimately be answered by events that have not yet happened. If Iran's new Supreme Leader Mojtaba Khamenei moves toward compliance with US demands on nuclear and missile programmes, Trump's Venezuela model will be vindicated and he will be able to claim a political as well as military victory. If Iran reconstitutes its capabilities and the IRGC consolidates power in the vacuum left by the killing of civilian and clerical leaders, then the military gains of Operation Epic Fury will have produced a more dangerous adversary rather than a compliant one.

The Strait of Hormuz remains the most consequential unresolved issue. A full reopening would signal that Iran has accepted its position and is willing to operate within constraints imposed by US military supremacy. A mining of the Strait, which US intelligence says Iran may be preparing, would signal the opposite: that Tehran intends to make the cost of the war permanent and global regardless of what happens to its nuclear programme. That single variable, open or mined, will do more to determine the war's true outcome than any number of press conferences in Washington or Tehran.

For now, both sides are claiming victory and neither is finished. The most honest answer to who won is that the US and Israel won the war they planned to fight, and Iran is now fighting a different war, one of attrition, economics and institutional survival, whose outcome is not yet determined.
