The Killing of Khamenei: How a Joint US-Israeli Strike Plunged the Middle East Into Open War

On the morning of February 28, 2026, Israeli jets dropped 30 bombs on a compound in the heart of Tehran. Hours later, Iranian state television confirmed what would have been unthinkable just days earlier: Supreme Leader Ayatollah Ali Khamenei, 86 years old and the architect of Iran's theocratic state for more than three decades, was dead [1][2][3].

The strike, carried out as part of a joint US-Israeli military operation codenamed "Epic Fury," did not merely kill Iran's most powerful figure. It decapitated the country's national security establishment, killing the defense minister, the commander of the Islamic Revolutionary Guard Corps (IRGC), and the secretary of Iran's Supreme National Security Council [4]. Within hours, Iran declared 40 days of national mourning — and unleashed retaliatory strikes across the Middle East that have pushed the region into its most dangerous crisis in decades [3].

Operation Epic Fury: The Opening Salvo

President Donald Trump announced the strikes in a video posted on Truth Social, framing them as a final resort after months of failed diplomatic negotiations over Iran's nuclear program [5]. The operation was massive in scale: more than 130 cities across Iran came under attack in the opening days, according to casualty trackers [6]. The Iranian Red Crescent Society initially reported more than 200 killed, a figure that climbed to at least 555 by March 2 [6][7].

The strikes targeted military facilities, nuclear sites, and leadership compounds. Israeli security officials briefed on the operation confirmed that Khamenei's office was a primary target [4]. The daylight raid on his compound — an extraordinary act of targeted assassination against a sitting head of state — drew immediate comparisons to some of the most consequential military operations in modern history.

The operation was launched without congressional authorization, a fact that immediately ignited a constitutional firestorm in Washington [8]. Trump declared that the war would last "four or five weeks" and that operations would continue "until all objectives are met" [9][10].

Iran Strikes Back: Missiles Across the Region

Iran's retaliation was swift and broad. On the morning of March 1, the IRGC launched missiles and drones at targets across the region — not only at Israel, but at US military assets and allied nations hosting American bases [7][11].

The list of countries struck by Iranian ordnance reads like a map of American military infrastructure in the Middle East: Qatar, the United Arab Emirates, Kuwait, Bahrain, Jordan, Saudi Arabia, Iraq, and Oman [3][11]. The IRGC said it launched attacks on 27 bases where US troops are stationed [3].

The human cost was immediate. US Central Command confirmed that at least six American service members were killed, with five seriously wounded and others sustaining shrapnel injuries and concussions [12][13]. Naval Support Activity Bahrain, Ali Al Salem Air Base in Kuwait, and Al Udeid Air Base in Qatar were all hit by projectiles [12]. Preliminary casualty figures across all parties showed at least 555 dead in Iran, 10 in Israel, six US soldiers, and five killed in Gulf states [6].

Trump responded by calling Khamenei "one of the most evil people in History" and warning Iran that if it continued retaliating, it would be hit "with a force that has never been seen before" [14].

Hezbollah Breaks the Ceasefire

The killing of Khamenei sent shockwaves far beyond Iran's borders. On March 1, Hezbollah — the Lebanese militant group that had maintained a fragile ceasefire with Israel since November 2024 — fired rockets at northern Israel for the first time in over a year [15][16].

Hezbollah explicitly framed the attack as "revenge for the blood of the Supreme Leader of the Muslims, Ali Khamenei" [17]. The group fired rockets at the Mishmar military site near Haifa, formally entering the conflict [18].

Israel's response was immediate and devastating. IDF Chief of Staff Lt. Gen. Eyal Zamir announced an "offensive campaign" against Hezbollah, stating: "We are not just on the defense, now we go on the offense" [16]. Israeli strikes on Beirut killed at least 31 people and injured 149, according to Lebanon's Health Ministry [19].

In a notable development, Lebanese Prime Minister Nawaf Salam condemned Hezbollah's actions, calling them "irresponsible" and announcing a total ban on all military activities by the group, demanding it surrender its weapons to the state [16]. The move underscored the deep divisions within Lebanon over Hezbollah's decision to drag the country into a wider war.

The Strait of Hormuz Crisis

Perhaps the most far-reaching immediate consequence of the conflict has been the disruption to global energy markets. Within hours of the initial strikes, the IRGC transmitted warnings via VHF radio to vessels in the Strait of Hormuz — the narrow waterway through which 20 to 30 percent of the world's oil and gas supplies pass — declaring that no ships would be permitted to transit [20].

Although Iran did not formally declare a blockade, the threats proved effective. Ship-tracking data showed a 70 percent reduction in traffic through the strait, with approximately 150 freight ships, including many oil tankers, stalled [20][21]. Shipping giants Maersk, MSC, Hapag-Lloyd, and CMA CGM all suspended operations through the waterway [20].

Oil prices responded violently. Brent crude jumped approximately 9 percent, with analysts forecasting potential rises to $100 per barrel or higher if disruptions continue [22]. Ali Vaez, director of the Iran project at the International Crisis Group, warned that "closure of the Strait of Hormuz would disrupt roughly a fifth of globally traded oil overnight — and prices wouldn't just spike, they would gap violently upward on fear alone" [20].

QatarEnergy, one of the world's top LNG suppliers, announced it would halt production, removing a major source of liquefied natural gas from the global market [22].

The Leadership Vacuum in Tehran

Khamenei's death has created a constitutional crisis inside Iran. Under Article 111 of the Iranian Constitution, a three-member transitional council was formed to govern until the 88-member Assembly of Experts can choose a new supreme leader [23][24]. The council consists of Ayatollah Alireza Arafi, President Masoud Pezeshkian, and Supreme Court Chief Justice Gholam-Hossein Mohseni-Ejei [24].

But the real power dynamics are murkier. The IRGC commander was also killed in the strikes — the second such killing in less than a year — leaving the country's most powerful military force without its top leader [24]. IRGC-linked Telegram channels have pointed to deputy chief Ahmad Vahidi, appointed to his position by Khamenei just two months before the assassination, as the likely successor [24].

Analysts at Foreign Policy noted that Iran's system was "built to withstand" the loss of its supreme leader, with institutional redundancies designed for exactly this scenario [25]. But the simultaneous killing of the IRGC commander, the defense minister, and the security council secretary has created a vacuum that no institutional design fully anticipated.

The question haunting Tehran — and capitals across the region — is whether the IRGC will use the chaos to consolidate power behind the scenes, or whether the transitional council can assert civilian authority [26].

A World Divided: International Reactions

The UN Security Council convened in emergency session on February 28, but has been unable to pass any resolution [27]. Secretary-General António Guterres condemned the strikes, warning that "the alternative is a potential wider conflict with grave consequences for civilians and regional stability" [28].

The geopolitical fault lines are stark. Russia's UN Ambassador Vassily Nebenzia demanded that "the United States and Israel immediately cease their aggressive actions," while President Vladimir Putin described Khamenei's killing as a "cynical murder" that violated "all standards of human morality and international law" [14][29]. China's response was more measured in tone but equally critical [30].

The European Union called the conflict "greatly concerning" and urged restraint [29]. The Arab League's Permanent Observer delivered perhaps the most sobering assessment, stating that "the moment in which the Arab-Israeli conflict has expanded into a full-scale regional war" had arrived [29].

The Constitutional Battle at Home

In the United States, the strikes have reignited a decades-old debate over presidential war powers. The operation was launched without congressional authorization, and lawmakers on both sides of the aisle are pushing back [8][31].

In the Senate, Democratic Senator Tim Kaine and Republican Senator Rand Paul have introduced a bipartisan measure requiring explicit congressional authorization before further hostilities. A parallel House resolution, sponsored by Republican Thomas Massie and Democrat Ro Khanna, seeks to compel the administration to halt unauthorized military action [31].

Most congressional Republicans praised the strikes, arguing that war was Trump's "last resort" after failed diplomacy [31]. But the bipartisan dissent — particularly from libertarian-leaning Republicans like Paul and Massie — signals genuine institutional unease.

Legal experts have been skeptical of the administration's legal justification. CNN reported that constitutional scholars questioned whether the strikes met the threshold for self-defense under the War Powers Act [32]. The dual efforts in both chambers face "uphill battles to become law," given that similar previous efforts have failed [31].

Protests and Public Opinion

Anti-war demonstrations erupted across the United States on the day of the strikes. Hundreds protested near the White House, with additional demonstrations in Times Square, Los Angeles, Chicago, San Francisco, and more than a dozen other cities [33]. Pro-Iranian solidarity protests have continued in the days since.

The domestic political landscape remains deeply fractured, with the war adding another volatile element to an already polarized national conversation.

What Comes Next

As of March 3, the conflict shows no signs of abating. Trump has insisted operations will continue until objectives are met. Iran's interim leadership has shown no indication of capitulating. Hezbollah has opened a second front. The Strait of Hormuz remains effectively closed to commercial traffic.

The killing of Khamenei has achieved what decades of sanctions, covert operations, and diplomatic pressure could not: the removal of Iran's supreme leader. But it has also unleashed forces — military, political, and economic — that no single actor can fully control.

The Arab League's grim assessment may prove prophetic. What began as a targeted strike has, within days, escalated into the regional war that generations of diplomats worked to prevent. The question now is not whether this conflict will reshape the Middle East, but how profoundly — and at what cost.
