Israel, US bomb Iran: A timeline of how threats escalated into war

On February 28, 2026, the geopolitical landscape of the Middle East was irrevocably altered. What began as a weekend of escalating tensions ended with the confirmed death of Iran’s Supreme Leader Ayatollah Ali Khamenei—the man who had ruled Iran with an iron fist for 34 years. Joint US and Israeli airstrikes, codenamed Operation Epic Fury by Washington and Operation Shield of Judah by Israel, targeted Khamenei’s compound in Tehran, vaporizing the heart of Iran’s clerical leadership .

By March 1, the world woke to a new reality: the Supreme Leader was gone, the Islamic Revolutionary Guard Corps (IRGC) leadership was decapitated, the Strait of Hormuz was effectively closed, oil prices were skyrocketing, and President Donald Trump was calling on the Iranian people to “rise up” against their oppressors . This was not merely another escalation in the long-running US-Iran shadow war—this was a full-blown regional conflagration with global consequences.

This article examines the 10 most critical dimensions of this geopolitical earthquake, analyzing how it unfolded, where we stand now, and what comes next.

1. The Road to War: How Diplomacy Collapsed into Annihilation

The path to February 28 was paved with failed negotiations and mounting frustration. In the weeks leading up to the strikes, US and Iranian officials had been engaged in intense indirect talks in Geneva, mediated by Oman. These negotiations aimed to resolve long-standing disputes over Iran’s nuclear program, uranium enrichment levels, and international inspector access .

Omani Foreign Minister Sayyid Badr bin Hamad bin Hamood Albusaidi had described these as “the most intense and promising rounds of talks in recent history” . Yet beneath the surface, tensions were boiling. President Trump had set a 10-to-15-day deadline for meaningful diplomatic progress, publicly expressing frustration with what he viewed as Tehran’s obstructionist tactics .

The backstory is critical here. In June 2025, Israel had launched surprise attacks on Iranian nuclear sites while Tehran was simultaneously negotiating with Washington. Iran responded with missile barrages toward Tel Aviv, drawing the US into direct strikes on Natanz and Fordow. Trump had then claimed—controversially—that Iran’s nuclear program was “crippled,” though Tehran denied this . A fragile ceasefire held for six months, but trust was nonexistent.

By January 2026, Iran’s economy was in freefall. Bread riots erupted across the country as the rial became virtually worthless. Khamenei blamed Trump, security forces killed thousands of protesters, and Trump tweeted that “help coming soon”—though he held fire . Then came Geneva. When the talks failed to produce a breakthrough by late February, the military option was activated.

On February 28, at 9:45 AM Iran time, US and Israeli forces launched their coordinated campaign. The diplomatic path had ended; the path of fire had begun .

2. Operation Epic Fury: The Night the Sky Fell on Tehran

The military operation was breathtaking in its scale and precision. US Central Command described it as “major combat operations” aimed at “defending the American people by eliminating imminent threats” . The Israeli Defense Forces framed their participation as a “preemptive strike” against existential threats from Iran’s nuclear and missile programs .

The strikes targeted multiple layers of Iran’s national infrastructure:

First, air defense systems across the country were obliterated, clearing the path for deeper penetration. Second, missile and drone launch sites were hit to degrade Iran’s ability to retaliate. Third, and most dramatically, 30 bombs were dropped on Khamenei’s residence in Tehran . The compound was vaporized, and with it, the man who had been the final arbiter of power in Iran since 1989.

Explosions and fires were reported in at least 10 to 12 Iranian cities, with 24 out of 31 provinces suffering damage . The IRGC leadership was wiped out in a single stroke: senior commanders including Gen. Pakpour, Mousavi, Nasirzadeh, and Shamkhani were confirmed dead . Iran’s state-run IRNA news agency also reported that a girls’ school in Minab, southern Iran, was struck, killing at least 57 students—a tragedy that would fuel outrage and retaliation .

For hours, confusion reigned. Iranian sources initially claimed both Khamenei and President Masoud Pezeshkian were unhurt . Israeli media reported that Khamenei had been cut off from communication and his fate remained unknown . But by March 1, the truth was undeniable: Iran’s Supreme Leader was dead.

3. Confirmation and Aftermath: A Leadership Vacuum

On March 1, Israeli Prime Minister Benjamin Netanyahu announced to the world that “Khamenei eliminated” . President Trump followed with a social media post declaring, “One of the most evil figures in history, Khamenei, has died. This is justice for Americans and all people around the world” .

Iran initially denied, then confirmed 12 hours later. State television announced the death, and 40 days of national mourning were declared . President Pezeshkian called the assassination “an open declaration of war against Muslims, and particularly against Shiites, everywhere in the world,” vowing that “revenge and punishment are our duty” .

The immediate challenge for Tehran was succession. According to Iran’s constitution, a transitional leadership council comprising President Pezeshkian, judiciary chief Gholamhossein Mohseni-Ejei, and a representative from the Guardian Council assumed temporary control . This body is tasked with governing until the Assembly of Experts—a panel of clerics—can convene to select a permanent successor.

But convening the Assembly of Experts under current conditions is nearly impossible. The security crisis means members cannot meet safely. Meanwhile, reports emerged that Khamenei’s son, Mojtaba Khamenei, was being positioned as a potential successor, though this would represent a dynastic shift that many hardliners might resist . Other potential names include Ali Larijani, a senior advisor, and top clerics like Alireza Arafi .

The IRGC, however, may not wait for clerical procedures. Analysts warn that a military leader could seize effective control to direct the war effort and crush domestic dissent . Ahmad Vahidi, a former defense minister, was swiftly appointed as the new IRGC commander, signaling that the Guards intend to remain the central pillar of power .

4. Iran’s Retaliation: Missiles, Drones, and a Regional War

Within an hour of the US-Israeli strikes, Iran’s Islamic Revolutionary Guard Corps launched massive retaliatory strikes. Ballistic missiles and drones rained down on Israel and US military facilities across the Gulf region .

The targets were extensive:

• Israel: Central Tel Aviv and residential areas were hit, with at least nine Israeli civilians confirmed dead .
• Gulf bases: US military installations in Qatar, Kuwait, Bahrain, the UAE, and Saudi Arabia came under attack. Al Udeid Air Base in Qatar—home to US Central Command’s forward headquarters—and the US Navy’s 5th Fleet headquarters in Bahrain were specifically named by Iranian media .
• Saudi Arabia: Explosions were heard in Riyadh, and oil infrastructure was targeted .
• Dubai and Doha: Hotels were damaged in Dubai, and explosions were heard in Doha as Iranian attacks continued .

Iran’s leadership made clear that no US asset in the region was safe. “All U.S. military bases in the region are legitimate targets,” the IRGC declared . Security chief Ali Larijani issued a thinly veiled threat to Trump himself, warning him to be careful “not to be eliminated” .

The IRGC also mocked Trump’s attempt to downplay the economic impact, vowing: “The Iranian armed forces… will not allow the export of a single litre of oil from the region to the hostile side and its partners until further notice” .

5. The Oil Shock: Strait of Hormuz Closed, Global Economy Reeling

Perhaps the most immediate global consequence of the conflict has been the effective closure of the Strait of Hormuz, through which an average of 20 million barrels of crude oil—about 20-30% of the world’s supply—pass daily .

Iran made good on its threats. On March 10, Tehran officially vowed that not one liter of oil would be exported from the Gulf while US-Israeli bombing continued . The UAE was forced to close its biggest oil refinery at Ruwais after a drone attack caused a fire. Qatar paused LNG exports from Ras Laffan under drone threat, sending European energy prices soaring . Saudi Aramco’s Ras Tanura refinery saw smoke plumes rising after attacks.

The market panic was immediate and severe:

• Oil prices surged from $82 to $98 per barrel overnight—a 20% spike .
• Brent crude briefly swept past $100 and was up 30% on some days before volatile trading set in .
• Natural gas prices jumped 30% .
• European governments began warning of a confirmed gas crisis heading into winter .

For countries like Pakistan and India—heavily reliant on Gulf oil and remittances—the impact has been catastrophic. Petrol prices in Pakistan were projected to hit 375 PKR per liter, with riots becoming imminent . Egypt increased fuel costs by up to 30% . The global economic outlook grew increasingly volatile, with analysts warning that the longer the disruption continues, the more drastic the consequences for the world economy .

Trump’s response has been to pressure allies—including NATO members, Japan, South Korea, and Britain—to send warships to help secure the strait . But most have balked. Germany’s defense minister bluntly stated, “This is not our war,” while UK Prime Minister Keir Starmer insisted Britain would not be drawn into a “wider war,” though mine-hunting drones might be provided .

6. Trump’s Endgame: Regime Change or Chaos?

President Trump has been remarkably transparent about his objectives. In his March 1 announcement, he framed Khamenei’s death as “the single greatest opportunity for the Iranian people to reclaim their country” . He called on Iranian military and security forces to lay down their arms, promising: “They may have immunity now, but later there will only be death” .

This is a classic two-pronged strategy: military destruction of Iran’s nuclear and missile capabilities, combined with political warfare aimed at triggering a popular uprising. Trump’s video message to the Iranian people declared: “Your oppressors are falling. Military surrenders = immunity. Rise up after we finish!” .

But the strategy carries enormous risks. First, it assumes that the Iranian public will rise up despite decades of brutal repression and the current wartime atmosphere. Historically, external threats have acted as a powerful unifying force in Iran. During the Iran-Iraq War of the 1980s, the regime consolidated nationalist sentiment through resistance against Saddam Hussein’s invasion . Similarly, US demands that Iran abandon its nuclear program have been portrayed as an affront to national dignity .

Second, it assumes that a post-Khamenei Iran will be more pliable. Yet intelligence sources warned Trump before the strikes that attacking Iran would likely strengthen hardline elements and lead to a more dangerous military leadership . Former National Security Advisor John Bolton confirmed that Trump was personally briefed multiple times on these scenarios, including the risk that Iran would retaliate against Gulf neighbors and choke off the Strait of Hormuz .

Trump has since claimed he was “shocked” that Iran attacked other countries, insisting “nobody expected that” . But Bolton and other sources dispute this, saying the warnings were explicit and detailed .

7. The Succession Crisis: Who Rules Iran Now?

The death of Khamenei has plunged Iran into its most severe leadership crisis since the 1979 revolution . While the constitutional mechanisms for succession exist, they were designed for peacetime, not wartime with the country under constant bombardment.

The Assembly of Experts—the body officially tasked with selecting a new Supreme Leader—cannot meet safely. Its members are scattered, and many may themselves be targets. This creates a power vacuum that multiple actors are rushing to fill.

The key contenders include:

• Mojtaba Khamenei: The late leader’s son has been waiting in the wings for years. His elevation would transform the Islamic Republic into a de facto dynasty, which could alienate hardliners who oppose hereditary succession .
• IRGC leadership: With the Guards now effectively running the war, they may simply seize control and install one of their own. Analysts warn this could lead to a “rump IRGC regime” ruling Tehran, even more hardline and unpredictable than before .
• Clerical figures: Judiciary chief Ejei, Ali Larijani, and senior clerics like Alireza Arafi and Mohsen Araki are all potential compromise candidates .
• President Pezeshkian: As a reformist not closely tied to the clerical establishment, Pezeshkian could theoretically emerge as a unifying figure, but his power base is weak without IRGC support .

The reality is that Iran may now be ruled by committee—or by competing factions. The IRGC’s provincial commanders and proxy leaders across the region may increasingly act on their own initiative, with no central authority capable of restraining them .

8. The Human Cost: Civilians Caught in the Crossfire

Amid the geopolitical analysis, it is essential to remember the human beings whose lives have been shattered by this conflict. The confirmed death toll is already staggering, and the real numbers are likely far higher.

Iran: Initial reports confirmed 555+ dead from the February 28 strikes, including senior IRGC commanders . But this figure almost certainly undercounts civilian casualties. The Minab school strike alone killed at least 57 girls . Realistic estimates suggest the true toll may be 2,000 to 3,000 .

Israel: Nine Israeli civilians were confirmed dead from Iranian missile strikes on Tel Aviv and other areas .

United States: Three US soldiers were killed in Gulf operations by March 2, with at least 13 confirmed dead by mid-March and 200+ wounded .

Gulf states: Casualties across Qatar, Kuwait, Bahrain, and the UAE are still being tabulated but are rising .

Lebanon: Hezbollah’s involvement has drawn Israeli retaliation, with dozens killed in Beirut suburbs .

Pakistan: Violent clashes erupted as Shiite protesters tried to storm the US Consulate in Karachi, resulting in at least 9 deaths from police fire .

Beyond the dead, millions face economic devastation. Thirteen million South Asian workers in the Gulf face unemployment as economies shut down. Remittances—a lifeline for countries like Pakistan and India—have dried up . The ripple effects will be felt for generations.

9. The Regional Domino Effect: From Hezbollah to Pakistan

The war is no longer confined to Iran. It has metastasized across the region:

Lebanon: Hezbollah rockets have hit Israel, prompting the IDF to flatten Beirut suburbs. The Lebanese government, under immense pressure, has banned Hezbollah’s military wing—a massive internal betrayal that could trigger civil war . Hezbollah leader Hassan Nasrallah is reportedly hiding in bunkers as his organization faces its greatest crisis .

Gulf states: Saudi Arabia, Qatar, and the UAE—once content to let the US handle Iran—are now direct targets. Their air forces are engaged in shooting down Iranian drones and missiles, fundamentally altering the regional security dynamic .

Pakistan: The country faces a perfect storm: an Iran-US war spilling over its western border, an ongoing Taliban conflict in the north, the Gulf economic collapse hitting remittances, and a resurgent TTP internally . Pakistan has announced naval escorts for commercial shipping, but its resources are stretched thin .

Iraq: Pro-Iran demonstrators have clashed with security forces near the heavily fortified Green Zone in Baghdad, attempting to approach the US Embassy . The Iraqi government is caught between Tehran and Washington.

India: Large Shiite crowds have taken to the streets in Indian-controlled Kashmir and other cities, carrying portraits of Khamenei and waving black flags .

10. The Strategic Balance: Why Iran Cannot Win a Long War

Despite the ferocity of Iran’s retaliation, the strategic balance heavily favors the US and its allies. Iran’s strengths are asymmetrical and short-term; its weaknesses are structural and long-term.

Iran’s advantages:

• Large missile and drone arsenals (3,000-5,000 remaining, but burning fast) 
• Ability to threaten oil shipping and Gulf infrastructure
• Proxy networks across Lebanon, Iraq, Syria, and Yemen
• Willingness to absorb casualties

Iran’s disadvantages:

• No air force capable of challenging US/Israeli supremacy
• Dependence on foreign components (e.g., Chinese chips for drones) that are now choked off 
• Oil exports at 10% of normal capacity due to strikes and blockade 
• Economy in freefall—the rial is effectively worthless 
• Leadership decapitated and factionalized
• No path to nuclear breakout without being hit again

The US and Gulf allies, by contrast, possess:

• Total air superiority
• Unlimited precision strike capability
• Vast financial resources (trillions vs. billions)
• Unassailable bases at Diego Garcia, Qatar, and Bahrain 

As one analyst put it: Shahed drones cost $20,000 each; Patriot missiles cost $2 million per intercept. Iran can win short-term attrition battles, but without oil revenue, the game ends in 90 days . The Trump administration is betting that the regime will collapse before Congress cuts off funding for an open-ended war.

Conclusion: A World on the Brink

The death of Ayatollah Ali Khamenei has shattered the Middle East’s fragile equilibrium. In its place, we have a region consumed by fire, a global economy teetering on the edge of recession, and a power vacuum in Tehran that could produce an even more dangerous adversary.

Several possible endgames now present themselves:

1. Iranian regime collapse (45% probability): If the economic strangulation continues and public dissent erupts, the clerical system could fall, replaced by something unknown . But as the ABC notes, “regime change is not a given”—the system was built to outlast any single man .

2. Nuclear crisis (25% probability): Desperate and cornered, Iran might sprint for a nuclear weapon. But with Fordow and Natanz already hit, this path is narrow .

3. Economic ceasefire (20% probability): Global oil interests—including China, which buys Iranian oil—could force a negotiated end. Trump has suggested the war will end “soon,” though fighting continues .

4. Full regional war (10% probability): Pakistan and Turkey could be dragged in, transforming the conflict into something truly apocalyptic .

For now, the world watches and waits. The streets of Tehran are quiet—for how long, no one knows. The Gulf remains closed. The missiles keep flying. And in Washington, Tel Aviv, and the bunkers where Iran’s remaining leaders hide, the next moves are being calculated.

One thing is certain: the Middle East will never be the same.
