This page provides the detailed military, diplomatic, and humanitarian timeline of Operation Epic Fury. For the war's economic transmission, electoral impact, and intersection with the populist thesis, see The Forces Shaping 2026, Section 5 in the main document.
The War Begins (Feb 28 - Mar 3)
On February 28, 2026, the United States and Israel launched joint strikes against Iran in an operation the Pentagon named "Operation Epic Fury." The strikes assassinated Supreme Leader Ali Khamenei and killed dozens of senior Iranian military and intelligence officials. Iran retaliated with hundreds of ballistic missiles and drones directed at U.S. military bases across the Gulf and at Israel. The conflict closed the Strait of Hormuz — through which approximately 20% of global oil and liquefied natural gas flows — and drew in Hezbollah, U.S. assets in Kuwait, Bahrain, Qatar, and Saudi Arabia, and expanded into active combat in Lebanon and Iraq [94].
Trump launched Operation Epic Fury without a vote of Congress, notifying the Gang of Eight shortly before strikes commenced and posting the announcement on Truth Social at 2:00 AM EST. He sent a War Powers notification letter to Congress days later — but the letter described the mission as "advancing national interests" rather than responding to an imminent threat, contradicting the administration's public justification for bypassing Congress [99].
Escalation and Failed De-escalation (Mar 4 - Mar 14)
By March 3, Brent crude had surged from under $70/barrel before the strikes to a peak near $120/barrel. Trump signaled a faster-than-expected end to operations around March 10, and oil retreated to approximately $85-90/barrel — but the pullback proved temporary.
Congress voted on war powers resolutions in both chambers. In the Senate, the measure failed 47-53, with Sen. Rand Paul (R-KY) the only Republican crossover and Sen. John Fetterman (D-PA) voting against alongside Republicans [104]. In the House, the resolution failed 212-219, with Reps. Thomas Massie (R-KY) and Warren Davidson (R-OH) the only Republican crossovers, and four Democrats — Henry Cuellar (TX), Jared Golden (ME), Greg Landsman (OH), and Juan Vargas (CA) — voting with Republicans [105]. A Senate group led by Sens. Booker, Baldwin, Duckworth, Kaine, Murphy, and Schiff announced plans to force additional votes unless Hegseth and Rubio testified publicly [106].
Five of the first six Americans killed in action were Army Reserve soldiers from the 103rd Sustainment Command based in Des Moines, Iowa [95]. Mojtaba Khamenei was elected new Supreme Leader on March 8.
By March 13, Brent had climbed back to approximately $100/barrel. Israel struck Kharg Island on March 13, targeting 90+ military targets while sparing oil infrastructure [120]. The Strait of Hormuz was effectively shut to commercial shipping. The IEA released 400 million barrels from strategic reserves (172 million from the U.S. Strategic Petroleum Reserve) [124].
As of March 14: 13 U.S. service members killed in action, 6 non-hostile deaths (KC-135 crash, western Iraq), approximately 140 wounded (8 severe) [120].
The Energy Infrastructure War (Mar 17 - Mar 19)
The conflict took a significant escalatory turn on March 18-19. Israel struck Iran's South Pars gas field — the world's largest natural gas field, shared with Qatar — the first Israeli attack on energy production infrastructure (as distinct from fuel depots). Iran retaliated by striking energy facilities across three Gulf neighbors: Qatar's Ras Laffan LNG terminal (the world's largest, sustaining "extensive damage" that knocked out 17% of Qatar's LNG export capacity), Saudi refineries in Riyadh, and UAE targets [150]. Qatar expelled Iranian military and security diplomats within 24 hours. Saudi Arabia warned it "reserved the right to take military actions" against Iran.
Trump claimed the U.S. "knew nothing" about the South Pars strike; Israeli and American sources contradicted him, with an Israeli source telling CNN the strike was carried out "in coordination with the United States" [150]. Trump then threatened to "massively blow up the entirety of the South Pars Gas Field" if Iran attacks Qatar again. Defense Secretary Hegseth announced the U.S. would unleash its "largest strike package yet" against Iran [150].
On March 19, Israeli forces struck targets in northern Iran for the first time and carried out strikes on Iranian naval targets in the Caspian Sea. The Pentagon announced 2,500 Marines deploying to the region. Reuters reported the administration was discussing potential ground forces at Kharg Island and to secure Iran's enriched uranium stockpiles; the White House stated "no decision to send ground troops at this time." Trump denied imminent deployment [151].
The Pentagon requested $200 billion in supplemental war funding. "It takes money to kill bad guys," Hegseth told reporters [151]. The request is roughly equivalent to the combined annual budgets of the Department of Education and the Department of Housing and Urban Development.
The Internal Fracture
The war produced its first major internal administration fracture on March 17. Joe Kent, director of the National Counterterrorism Center and a former Green Beret with eleven combat deployments, resigned, stating that "Iran posed no imminent threat to our nation" and that the war was started "due to pressure from Israel and its powerful American lobby" [152]. Kent, a Trump appointee confirmed by the Senate, told Tucker Carlson that there was "no intelligence" suggesting Iran was preparing a major attack and that "the Israelis drove the decision." The FBI subsequently confirmed it had been investigating Kent for months over alleged leaks of classified information — a probe that predated his resignation. Administration officials called Kent a "known leaker" who had been cut out of briefings.
Separately, Director of National Intelligence Tulsi Gabbard was accused of altering her Senate testimony on Iran, allegedly omitting intelligence details that contradicted the administration's claims about the threat Tehran posed [150].
The Coalition That Didn't Form
Trump sought a multinational naval coalition to reopen the Strait of Hormuz. The UK said it would not "be drawn in." Germany said it had "nothing to do with NATO." The EU said it was "out of NATO's area of action." Japan's Prime Minister Takaichi met with Trump on March 19 seeking help securing the Strait. A planned Trump-China summit (March 31-April 2) may be delayed as Trump remains in Washington to coordinate the war [120][122].
Humanitarian and Regional Impact
As of Day 21, the regional death toll exceeds 2,500 across all parties: over 1,444 in Iran (HRANA documented 3,114 including 1,354 civilians by March 17), over 1,000 in Lebanon, 18 in Israel, 61+ in Iraq, 21+ in Gulf states [150]. Iran Red Crescent reported 18,000+ injured in U.S.-Israeli strikes. The IMO is negotiating a humanitarian corridor for 20,000 seafarers stranded in the Gulf. QatarEnergy declared force majeure on gas exports.
U.S. casualties as of Day 21: 13 killed in action (hostile), 6 non-hostile deaths (KC-135 crash), approximately 200 wounded (180 returned to duty) [95][96][120].
Current Status (Mar 20, Day 21 — evening)
The conflict escalated further on March 20 even as Trump floated "winding down" rhetoric that was immediately contradicted by troop deployments and battlefield events.
Leadership and military developments: The IRGC's spokesman, Naeini, was killed in an Israeli airstrike shortly after telling the Associated Press that Iran was still manufacturing missiles — contradicting Netanyahu's claim the previous day that Iran "has no ability to produce ballistic missiles." An F-35 fighter jet made an emergency landing at a U.S. base in the Middle East after being hit by what is believed to be Iranian fire, the first successful Iranian strike on a U.S. aircraft since the war began (CENTCOM confirmed the pilot is in stable condition) [157]. Israel struck Tehran on the Persian New Year (Nowruz), hitting targets as Iranians marked the holiday. Israeli security forces shut Al-Aqsa mosque in Jerusalem for the first time since 1967, barring Muslim worshippers during Eid al-Fitr.
Energy infrastructure war — widening: Iran struck Qatar's Ras Laffan LNG facility again, cutting approximately 17% of Qatar's export capacity. QatarEnergy's CEO estimated up to five years to repair the damage, with annual losses near $20 billion — a figure representing roughly 9% of Qatar's GDP. Iranian drones struck Kuwait's Mina Al-Ahmadi refinery for the second time, sparking fires and a precautionary shutdown of several units. Iraq declared force majeure on all oilfields operated by foreign companies, citing inability to ship crude through Hormuz. Saudi Arabia intercepted a missile over its northern Al Jouf region. Iran warned the UAE it would subject Ras al-Khaimah to "heavy strikes" if its Gulf islands came under further attack [157].
Oil and energy prices: Brent crude closed at $112.19/barrel on March 20, up 3.26% — a new closing high since the war began. WTI settled at $98.32. Saudi officials told the Wall Street Journal that prices could exceed $180/barrel if disruptions last through late April. Citi raised its near-term Brent forecast to $120, with a bull-case scenario of $150 if disruptions intensify. Goldman Sachs warned that elevated prices could persist all the way through 2027. Gas reached $3.912/gal AAA nationally. Georgia became the first U.S. state to suspend its fuel tax (60-day suspension of 33 cents/gallon gas and 37 cents/gallon diesel), though Florida and Maryland declined to follow. The IEA issued an unprecedented advisory urging governments, businesses, and households to work from home, reduce highway speeds, and use public transportation to ease a "major energy crisis" [157].
Troop deployments vs. "winding down": Trump posted on social media that the administration is considering "winding down" military efforts. But officials confirmed that the USS Boxer group with the 11th Marine Expeditionary Unit departed California and will reach the Persian Gulf in approximately three weeks, joining the 2,500 Marines already deploying from Okinawa. Trump called NATO allies "cowards" for refusing to help secure the Strait of Hormuz. The Pentagon is reportedly preparing to ask Congress for up to $200 billion to continue funding the war. Asked about ground troops, Trump told reporters: "No. I'm not putting troops anywhere" — while the administration simultaneously discusses ground forces at Kharg Island [155][157].
Humanitarian toll: Iran Red Crescent reported at least 204 children among the 1,444+ killed in Iran and 18,000+ injured in U.S.-Israeli strikes. The Lebanese government confirmed over 1,000 killed, with a fifth of Lebanon's population displaced. In Israel, 18 civilians have been killed and over 4,000 injured. Bahrain's defense forces have intercepted 139 missiles and 238 drones since the start of the conflict.
No ceasefire path is visible. The conflict is no longer contained to Iran and Israel: energy facilities in Qatar, Kuwait, Saudi Arabia, and the UAE have been attacked, with regional powers threatening independent military responses. The pattern of Trump's rhetorical de-escalation followed by battlefield escalation — which characterized the first two weeks of the war — continues into Week 3.
Week 4: The Hormuz Ultimatum (Mar 21 - Mar 22)
The war entered its fourth week with the most direct threat yet to energy infrastructure and the most significant escalation in Iranian strike capability.
The 48-hour ultimatum (Mar 22): Trump posted on Truth Social: "If Iran doesn't FULLY OPEN, WITHOUT THREAT, the Strait of Hormuz, within 48 HOURS from this exact point in time, the United States of America will hit and obliterate their various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST!" Iran's armed forces headquarters responded within hours, declaring readiness to close the Strait indefinitely and threatening to destroy all energy infrastructure, IT systems, and water desalination facilities connected to the U.S. and Israel across the entire region. Separately, Iran's representative to the International Maritime Organization told Mehr News Agency that the Strait of Hormuz remains open to all nations except Tehran's "enemies."
Iranian strikes on Israeli nuclear zone (Mar 21-22): Iranian missiles penetrated Israeli air defenses and struck the southern cities of Dimona and Arad — near Israel's main nuclear research center at the Negev Nuclear Research Center. Over 100 Israelis were injured, dozens of buildings destroyed, including a children's afterschool center. It was the first time Iran had targeted the vicinity of Israel's nuclear complex during the war. Netanyahu visited the crater in Dimona and called the strikes an attack on "the entire world." A separate Iranian strike hit the Tel Aviv area on March 22, injuring 15 [158].
Diego Garcia — ICBM-range attack: Iran fired two ballistic missiles at Diego Garcia, the joint U.S.-UK military base in the Indian Ocean approximately 2,000 miles south of Iran. Neither struck the base. Netanyahu cited the attack as evidence Iran can "reach deep into Europe" and urged world leaders to "join up." The UK confirmed it had previously allowed U.S. use of British bases for "defensive" strikes on Iranian targets — prompting Iran to warn that British lives were in danger [158].
Lebanon escalation: Israel struck a critical bridge over the Litani River in southern Lebanon, severing a key transit connection. Lebanese President Joseph Aoun called the strike "unjustified" and warned it was "a prelude to a ground invasion." Aoun has offered direct negotiations with Israel and pledged to disarm Hezbollah. The Israeli military announced new strikes in Lebanon targeting Hezbollah infrastructure. Hezbollah rockets and drones continued pounding northern Israel [158].
Regional defense totals: Bahrain's military reported shooting down 143 missiles and 242 drones fired by Iran during the war. Saudi Arabia intercepted three ballistic missiles targeting Riyadh and six drones headed toward its eastern oil region. The UK Maritime Trade Operations reported 21 confirmed attacks on commercial vessels and offshore infrastructure since March 1, with the threat level across the Gulf and Strait of Hormuz at "critical" [158].
Iran's 70th wave of attacks: The Iranian armed forces announced their 70th wave of attacks since the war began, launching missiles and drones toward Israel and U.S. bases in the Gulf. Iran also claimed to have intercepted a U.S.-Israeli armed drone over Tehran and shot down a third Israeli fighter jet in Iranian airspace [158].
Airlines respond: United Airlines became the first major U.S. carrier to cut capacity, announcing a 5% reduction in Q2-Q3 flights. CEO Scott Kirby said jet fuel prices had more than doubled in three weeks, adding an estimated $11 billion in annual fuel expense — more than double United's best-ever profit. United is modeling oil at $175/barrel and expects prices above $100 through 2027. Delta indicated it may follow with its own cuts [159].
Diplomatic activity: Turkish Foreign Minister Hakan Fidan held meetings with Iranian and Egyptian foreign ministers and with the EU's Kaja Kallas. No ceasefire framework has emerged. Ukrainian President Zelensky told the BBC that the Iran war is delaying his trilateral meetings with Western allies: "For Putin, a long war in Iran is a plus" — as rising oil prices and suspended U.S. sanctions on some Russian crude benefit Russia's economy.
Current Status (Mar 23, Day 24)
On Day 24, Trump abruptly reversed course on the power plant ultimatum, opening the first potential diplomatic window since the war began — though its durability is uncertain.
The 5-day postponement: Trump posted on Truth Social that the U.S. and Iran had held "very good and productive conversations regarding a complete and total resolution of our hostilities in the Middle East." He ordered the military to postpone strikes on Iranian power plants and energy infrastructure for five days, extending the deadline that had been set to expire Monday evening. Trump told CNN there are "15 points of agreement" and told CNBC he is "very intent on making a deal." He identified Steve Witkoff and Jared Kushner as the envoys conducting talks, saying discussions began Saturday night and continued through Sunday, facilitated by messages through third countries. Trump said Iran called him, not the other way around, and that any deal must include Iran giving up its enriched uranium stockpile [167].
Iran denies talks: Iran's parliament speaker, Mohammad Bagher Ghalibaf, posted on X that no negotiations between Washington and Tehran had taken place. Iran's foreign ministry said messages from "friendly countries indicating a U.S. request for negotiations" had been received but that Trump's move was aimed at lowering energy prices and buying time for military plans. The foreign ministry warned that any attack on Iran's energy infrastructure would still be met with a "decisive response." Iran's Defence Council escalated further, announcing that an attack on Iran's southern coast or islands would lead to the laying of sea mines throughout the Gulf: "In this case, the entire Gulf will practically be in a situation similar to the Strait of Hormuz for a long time" [167].
Strikes continue despite talk of talks: Even as Trump signaled de-escalation, Israel launched what Al Jazeera's Tehran correspondent described as "unprecedented" wide-scale strikes on the Iranian capital, with explosions on the eastern side of the city larger than any previous attacks. The Israeli military confirmed a second round of strikes hours after the first. Iran fired cluster warhead-equipped ballistic missiles at the Tel Aviv metropolitan area, with impacts reported in Tel Aviv, Ramat Gan, Petah Tikva, and Holon. A kindergarten in Rishon LeZion was hit in recent days. The Dimona casualty toll from Saturday's attack rose to at least 180 injured. Iran announced its 70th wave of attacks and 337 total attack waves on Israel since the war began [167].
Regional toll and defense totals: The UAE Ministry of Defense reported intercepting 7 ballistic missiles and 16 UAVs on March 23 alone; since the war began, the UAE has been targeted by 352 ballistic missiles, 15 cruise missiles, and 1,789 UAVs. Iran's Health Ministry revised the national death toll to 1,500+ killed (up from the 1,200 figure previously reported by the Red Crescent). Lebanon: 1,039 killed (2,876 wounded, 10 deaths and 90 injuries in the past 24 hours; more than 100 children per WHO). Iraq: 60 killed. Israel: 15 killed, over 4,000 injured. U.S.: 13 killed in action, 2 non-combat deaths, approximately 200 wounded. West Bank settler violence has surged to an average of 10 attacks per day since March began; IDF Chief of Staff Zamir condemned the violence and ordered reinforcements to the Central Command [167][168].
Oil and markets: Brent crude opened above $114 Monday morning, then crashed more than 10% to settle at $99.94 — its first close below $100 since March 11 and the biggest single-day drop since March 10. WTI settled at $88.13 (-10.28%). Markets rallied but pared gains into the close: Dow +1.38% to 46,208, S&P 500 +1.15% to 6,581, Nasdaq +1.38%. All three remain below their 200-day moving averages. Gold fell more than 6%. Goldman Sachs raised its Brent forecast to $110 for March-April, warning prices could exceed the 2008 record of ~$147 if Hormuz remains at 5% of normal flow for 10 weeks. The IEA head said the crisis is "worse than the two oil crises of the 1970s combined" [167].
Diplomatic signals: Turkey's foreign minister conducted more than a dozen calls with regional and global counterparts over the weekend. EU Commission President von der Leyen said "it's time to go to the negotiation table and end the hostilities." Iran's foreign minister spoke with Oman's foreign minister, suggesting a potential back-channel. Egypt said it "appreciates" Trump's decision to pause strikes. UK PM Starmer called for an emergency meeting on the economic fallout [167].
DHS and domestic politics: The Senate confirmed Sen. Markwayne Mullin as DHS Secretary in a 54-45 vote Monday evening. Fetterman and Heinrich were the two Democratic votes; Rand Paul the sole Republican no. Mullin replaces Kristi Noem and takes over a department in its 37th day of a partial shutdown. Trump rejected a proposal to fund all of DHS except ICE, instead demanding Democrats pass the SAVE America Act (a voter ID and elections overhaul bill). Thune called the demand "not realistic." More than 400 TSA officers have quit; record 11.5% single-day callout rate Saturday. Mullin's departure creates an Oklahoma Senate vacancy; Gov. Stitt is appointing energy executive Alan Armstrong, with Rep. Kevin Hern running for the full term.
The war's trajectory remains uncertain. Trump's postponement buys time, but Israel's continued strikes and Iran's denial of negotiations suggest neither side has committed to a ceasefire path. The five-day window expires on March 28.
