As bombs fall on Tehran and tankers sit idle at the mouth of the world’s most critical energy chokepoint, the full consequences of America’s most audacious military gamble since the invasion of Iraq are only beginning to reveal themselves.
Five days into the US-Israeli air campaign against Iran, the strategic picture is simultaneously clearer and more alarming than Washington’s architects of “Operation Epic Fury” anticipated. Brent crude has surged past $83 a barrel. Qatar has shuttered its liquefied natural gas facilities after Iranian drone strikes on Ras Laffan. European natural gas futures have spiked 30 percent. And the Strait of Hormuz — the narrow passage through which one-fifth of the world’s daily oil supply flows — has, for the first time in history, effectively ceased to function as a commercial waterway.
This is not the controlled, limited operation that June 2025’s nuclear strikes were designed to be. This is something else entirely.
From Midnight Hammer to Epic Fury: Why This Time Is Different
To understand the magnitude of the gamble underway, one must first appreciate how deliberately constrained the June 2025 strikes were by comparison. When US and Israeli forces hit Iran’s nuclear enrichment sites eight months ago, the operation carried an implicit message: this is about the bomb, not the regime. Targets were specific. Escalation ladders were left intact. Supreme Leader Ali Khamenei was conspicuously, almost theatrically, left alive.
February 28, 2026 was an entirely different doctrine in action. According to the House of Commons Library’s real-time briefing on the conflict, Trump’s Truth Social statement that day declared the operation would “annihilate” Iran’s navy, destroy its missile infrastructure, and dismantle the network of Iran-backed armed groups across the region. This was not a surgical strike. It was a decapitation campaign.
The results were staggering in their immediate scope. Israel has claimed that a majority of Iran’s senior military leadership was killed in the initial wave — including the armed forces chief of staff, the commander of the Islamic Revolutionary Guard Corps, and the secretary of Iran’s Defence Council. And then, confirmed by Iranian state media on the morning of March 1, came the killing that changes everything: Supreme Leader Ayatollah Ali Khamenei, 86 years old, dead at his office within his residence, after 37 years atop the Islamic Republic.
The strategic logic driving the escalation from June to February is traceable. Iran, warned by the June strikes but unbowed, quietly rebuilt portions of its nuclear programme at hardened underground sites, according to the White House’s pre-strike briefing. Nationwide protests that erupted in late December 2025 — the largest since the 1979 revolution, spreading to over 100 cities — were met with a brutal crackdown that the US-based Human Rights Activists News Agency estimated killed 7,000 Iranians. Trump had called the crackdown a red line. His February 13 statement that regime change in Iran would be “the best thing that could happen” was not, in retrospect, rhetorical flourish. It was policy.
The Regime Is the IRGC: Why Decapitation Is Not Regime Change
President Trump’s framing of the operation as a “liberation” moment — his Truth Social video urging Iranians to “take over your government, it will be yours to take” — reflects either a profound misreading of the Islamic Republic’s architecture, or a deliberate willingness to ignore it.
The Council on Foreign Relations was characteristically blunt in the immediate aftermath of Khamenei’s death: taking out the supreme leader is not the same as regime change, because the IRGC is the regime. The IRGC is not a military subordinate to the supreme leader; it is the structural spine of the state, constitutionally tasked with protecting the velayat-e faqih system, with its own economic empire, its own intelligence apparatus, and its own foreign policy executed through proxy forces from Lebanon’s Hezbollah to Yemen’s Houthis. The Basij paramilitary militia is embedded in every neighbourhood in Iran.
Under the constitution, a three-person interim leadership council has assumed power, comprising President Masoud Pezeshkian, Judiciary Chief Gholam-Hossein Mohseni-Ejei, and senior conservative cleric Alireza Arafi. The Assembly of Experts — 88 clerics — must ultimately choose a successor. According to CNN’s analysis of the succession process, Trump himself observed, with characteristic dark humour, that “the attack was so successful it knocked out most of the candidates. It’s not going to be anybody that we were thinking of because they are all dead.”
A RAND Corporation analysis published this week identifies four possible trajectories for the Islamic Republic: organised clerical succession that maintains the status quo; a “cut and run” scenario in which key leaders flee (echoing Bashar al-Assad’s flight from Damascus in late 2024); a suppression-and-succession scenario in which the IRGC consolidates power into a quasi-military junta with weakened clerical legitimacy; or, least likely, a successful popular uprising. None of these outcomes, with the possible exception of the third, was what Washington intended. And the third may prove the most destabilising of all — a more conventionally militarised Iranian state, freed from the theological constraints of the clerical establishment, and with a nuclear programme, a ballistic missile arsenal, and a regional proxy network still largely intact.
Hassan Ahmadian, a professor at the University of Tehran, told Al Jazeera that Khamenei’s doctrine of “strategic patience” — absorbing blows to avoid all-out war — died with him. “Iran learned a hard lesson from the June 2025 war: restraint is interpreted as weakness. The decision has been made. If attacked, Iran will burn everything.” Whether those words represent the calculation of surviving IRGC commanders, or merely the rhetoric of a system under existential pressure, is a question with very high stakes attached to it.
The Pandora’s Box: Iran’s Retaliation Strategy in the Gulf
Iran has not needed to formally close the Strait of Hormuz to shut it down. That is perhaps the most strategically significant development of the past five days, and one with the deepest implications for how this conflict plays out.
The IRGC confirmed on March 2 that the strait was “closed,” warning that any vessel attempting transit would be set “ablaze.” But Iran did not need to mine the channel or deploy its navy in a conventional blockade to achieve the effect. Selective drone and rocket attacks on five tankers — killing two crew members and stranding approximately 150 ships at anchor outside the strait — proved sufficient to cause the complete commercial withdrawal of the world’s largest shipping operators. Maersk and Hapag-Lloyd have suspended all transits. Protection and indemnity insurance was removed effective March 5, making the economics of passage impossible for most operators. According to Kpler’s crisis analysis, the strait has reached a “de facto closure” driven by insurance withdrawal, even as a thin trickle of Iranian and Chinese-flagged vessels continues to move.
The attack on Qatar’s energy infrastructure has been the single most economically consequential act of Iran’s retaliation campaign. QatarEnergy confirmed Monday that it had ceased production of LNG and associated products at Ras Laffan Industrial City and Mesaieed Industrial City after drone strikes on both facilities. Qatar is the world’s largest LNG exporter. Roughly 20 percent of global LNG supply passes through the Strait of Hormuz, nearly all of it Qatari. European natural gas futures jumped 30 percent on the news. LNG tanker freight rates surged more than 40 percent in a single day.
Iranian strikes have also hit US diplomatic infrastructure across the Gulf. The US Embassy compound in Riyadh was struck by a drone on March 3, prompting its closure along with the embassy in Kuwait. The US State Department has urged all American citizens to leave the Middle East immediately. Meanwhile, Al Jazeera’s live coverage reports that the IRGC engaged 230 drones in ground force operations and announced a naval operation targeting US military ships — a significant escalation in tactical scope.
The Houthis’ announcement on February 28 that they would resume attacks on Israel and commercial shipping in the Red Sea adds a second simultaneous chokepoint to the crisis. With major carriers already rerouting around Africa’s Cape of Good Hope — adding weeks and significant cost to transit times — the combined disruption to the Suez Canal corridor and the Strait of Hormuz represents an unprecedented dual closure of the two arteries that move the world’s energy and consumer goods.
Economic Shockwaves: Oil, LNG, and the Gulf Nightmare
The numbers tell a story of markets that are, for now, managing fear rather than capitulating to it — but the trajectory is deeply concerning.
Brent crude opened the week at $73 a barrel. By Tuesday it had climbed past $83, a rise of more than 10 percent in 48 hours. The Dow Jones Industrial Average fell more than 1,000 points on Tuesday morning, its worst trading day since April 2025. The Nasdaq dropped 1.8 percent at the open. Yet against the severity of the underlying disruption, the crude market has been, as energy trader Rebecca Babin of CIBC Private Wealth told NPR, “extremely measured.” The reason is structural: markets entered this conflict with ample inventories, the result of Gulf states and Iran itself front-loading oil exports in the weeks before the anticipated strikes. China holds substantial crude reserves both onshore and in floating storage. OPEC+ has pledged to release an additional 206,000 barrels per day to mitigate shortages.
But the buffer is temporary and the tail risks are severe. JPMorgan analysts have warned that a conflict lasting more than three weeks would exhaust Gulf countries’ storage capacity as barrels build up with no way to reach export markets, potentially forcing production shutdowns. Under that scenario, Brent could reach $120 a barrel. If Iran succeeds in enforcing a full Hormuz closure through mines and sustained anti-ship missile deployment, one Deutsche Bank research analyst has suggested Brent could surge toward $200 — a scenario that MST Marquee’s Saul Kavonic describes as potentially “three times the severity of the Arab oil embargo and Iranian revolution of the 1970s.”
The Asian exposure is acute and uneven. China, India, Japan, and South Korea collectively account for 69 percent of crude oil flows through the Strait of Hormuz. South Korea and Japan hold roughly two to four weeks of LNG reserves at current demand levels, according to CNBC’s country-by-country analysis. Pakistan and Bangladesh are acutely exposed: Qatar and the UAE account for 99 percent and 72 percent of their LNG imports respectively. India, already pivoting toward Russian crude under the price-cap regime, will accelerate that substitution.
The conflict is, perversely, a strategic windfall for Moscow. With Middle Eastern barrels stranded and Asian buyers scrambling for alternatives, Russia’s competitive position in global crude markets has improved dramatically in the space of five days. The sanctioning coalition that has sought to cap Russian energy revenues since 2022 faces its greatest structural challenge since the invasion of Ukraine began.
Gulf States: Caught Between Washington and Tehran
The regional geopolitics are, if anything, more complicated than the energy economics. Saudi Arabia, the UAE, Kuwait, Qatar, Oman, and Bahrain have all condemned Iran’s retaliatory strikes on Gulf infrastructure while separately, and awkwardly, questioning the legal basis of the original US-Israeli campaign. Oman has been most explicit in its criticism. As noted in the House of Commons briefing, the think tank Chatham House has argued Arab Gulf leaders view “the greatest risks” as “an expansionist and aggressive Israel, and the chaos of a potentially collapsed Iranian state” — a formulation that captures the fundamental tension in their position.
The paradox for Riyadh and Abu Dhabi is sharp. Both lobbied Washington privately against military action for years, preferring the degradation of Iranian influence through sanctions and proxy competition to the catastrophic uncertainties of open war. Crown Prince Mohammed bin Salman reportedly made multiple calls to Trump urging him to strike — a reversal driven by the January crackdown on Iranian protesters and Tehran’s continuing nuclear ambitions. Having encouraged the blow, they now watch Iranian missiles arc toward their territory and infrastructure with the grim realisation that they are simultaneously beneficiaries of Iranian weakness and victims of its death throes.
The closure of the Strait is, in the medium term, as damaging to Gulf oil exporters as it is to Asian importers. Saudi Arabia’s East-West Pipeline and the UAE’s Fujairah pipeline offer partial bypass routes — but terminal constraints and throughput limits mean they cannot substitute for a full Strait closure. A war lasting more than three weeks risks not just stranded tankers but forced production curtailments at the Gulf’s largest fields.
What Regime Change Actually Means in 2026
The word “regime” in “regime change” has always concealed more than it revealed. Iran is not a conventional dictatorship in which authority flows from a single figure whose removal collapses the system. It is an institutionalised theocratic-military hybrid in which power is distributed — and contested — across the supreme leader’s office, the IRGC, the clergy, the presidency, the parliament, and the judiciary. Khamenei’s singular achievement over 37 years was not the consolidation of personal power but the institutionalisation of the velayat-e faqih principle across all of these structures simultaneously.
His death does not erase that institutionalisation. What it does is trigger a succession contest under conditions of maximum external pressure and domestic volatility — a combination that historically tends to strengthen the most coercive actors in any system. The IRGC, with 350,000 men under arms and deep penetration of Iran’s economy through its vast corporate empire, is structurally positioned to dominate the succession outcome regardless of which cleric is formally elected supreme leader.
The most dangerous scenario is not regime collapse. It is regime hardening: the emergence of a militarised, ideologically narrower, and even less diplomatically tractable Iranian state — one that has learned, from the decapitation of its clerical leadership, that theological legitimacy offers no protection, and that the only viable deterrent is escalation dominance in every available domain. As the Times of Israel reported from analysts at Sciences Po Grenoble, “the entire direction of the regime will depend on the choice of the new supreme leader” — but whoever that is, they will govern in the shadow of 230 drones and a closed strait.
The Road Ahead
Five days in, the contours of three possible outcomes are visible, though none is certain.
In the most optimistic scenario — the one markets appear, tentatively, to be pricing — the military campaign achieves its declared objectives within Trump’s stated four-to-five-week timeline. Iran’s missile infrastructure is sufficiently degraded to prevent sustained strikes on Gulf infrastructure. A surviving faction of the regime enters into negotiations. The Strait reopens within two to three weeks as insurance markets cautiously return. Brent stabilises in the $85-90 range. Global inflation absorbs a significant but not catastrophic supply shock, and the pressure fades over two quarters.
The middle scenario, which most serious analysts consider more probable, involves a protracted conflict extending beyond five weeks. Iran deploys residual missile capacity and proxy networks to sustain pressure on Gulf infrastructure and US military bases. Qatar’s LNG shutdown extends for weeks. Brent reaches $100-120. The IRGC consolidates power under a hardline clerical figurehead. Trump faces growing domestic political pressure as pump prices rise. A negotiated pause — rather than resolution — eventually emerges, leaving Iran’s nuclear programme partially intact and the IRGC’s regional networks battered but functional.
The worst case — low probability but not negligible — is a full Strait closure sustained through mine-laying and anti-ship missile deployment, combined with successful strikes on Saudi and UAE production infrastructure. Brent toward $150-200. European natural gas prices retesting the 2022 crisis highs. Global recession. An Iran that, in the chaos of succession and military pressure, either fragments into competing factions or coalesces into an IRGC junta with nothing left to lose and no diplomatic assets worth preserving.
What is already clear, beyond any scenario planning, is that the June 2025 and February 2026 operations represent a strategic discontinuity whose full consequences will take years to resolve. The United States has crossed a threshold from which there is no clean return: it has killed the supreme governance authority of a major regional power, in what it has defined as self-defence under Article 51 of the UN Charter. Every state in the world is now recalculating what that precedent means.
History’s Pandora’s boxes rarely announce themselves at the moment they are opened. They reveal their contents gradually, over years and decades, in consequences that feel, at each stage, like the product of earlier choices made by other people. The choice was made on February 28, 2026. The contents are still emerging.
