On March 31, President Trump announced plans to end U.S. military operations against Iran within three weeks — with or without a deal. Analysts warn this is less a resolution than a strategic exit: Washington is declaring victory, washing its hands of the Strait of Hormuz, and telling energy-dependent allies to fend for themselves.
Mission Accomplished — Plus Regime Change
Speaking from the Oval Office, Trump was blunt: "We'll be leaving, because we don't have any reason to continue doing this." He claimed the operation had achieved its sole objective — preventing Iran from acquiring nuclear weapons — and that regime change came as an unexpected bonus. "They won't have nuclear weapons. That goal has been achieved."
He insisted U.S. forces would withdraw regardless of whether Tehran signs any agreement, though he suggested a deal was likely given Iran's eagerness. He did not identify which Iranian faction Washington is negotiating with, saying only that the new leadership is "much easier to talk to." White House Press Secretary Karoline Leavitt separately outlined four military objectives: dismantling Iran's navy, ballistic missile arsenal, and defense industrial base, and blocking nuclear acquisition.
Passing the Strait
The war's most disruptive global side effect has been Iran's blockade of the Strait of Hormuz, through which roughly 20 percent of the world's seaborne oil passes. Trump's response has been a textbook "America First" shrug.
Frustrated that NATO allies have done little to help reopen the waterway, Trump told the New York Post the strait would reopen automatically once Iran was sufficiently weakened. "Let the countries that use it open it," he said. "We're not going to manage that anymore." On social media, he addressed affected allies directly: "America will not be there to help you anymore. Go get your own oil" — singling out France by name.
Defense Secretary Pete Hegseth echoed the sentiment at a March 31 press conference: "Reopening the strait is not just America's problem." Secretary of State Marco Rubio struck a more measured note, calling it unacceptable if Iran continued to control and extract tolls from the waterway after the operation ended.
Why Washington Wants Out
The exit is being driven by economics and electoral arithmetic. Brent crude surged roughly 60% in March alone, closing at a record $118.35 per barrel. The national average gasoline price crossed $4 per gallon for the first time since 2022 — a politically toxic threshold. Administration officials fear sustained inflation could prove fatal to Republican candidates in November's midterms, potentially costing the party its congressional majority.
Financial markets welcomed the news. The S&P 500 posted its largest single-day gain since May of last year after Iran's president signaled willingness to end the war, contingent on guarantees against further U.S. and Israeli strikes.
Still Hitting Hard
Despite the exit rhetoric, U.S. military pressure has not eased — a classic coerce-to-negotiate posture. The Pentagon is deploying a third carrier strike group, the USS George H.W. Bush, to join two already in the region. Hegseth warned that the "coming days will be decisive" and that the U.S. stood ready to escalate if Iran failed to reach a deal.
Strikes remain intense. American forces used 2,000-pound bunker-busters to destroy an ammunition depot in Isfahan. The Mobarakeh steel plant near Isfahan was hit a second time on the night of March 31. Additional targets included the Sefid Dasht steel plant, Shahid Haqqani port, the commercial port at Bandar Abbas, and radar installations in Bushehr Province.
Gulf States Left Holding the Bag
The Arab Gulf states — long reliant on U.S. security guarantees — are the most anxious about Washington's departure. Trump sought to reassure them on Fox News, promising continued protection even without a permanent presence in Iran. Analysts are skeptical: ceding the strait to other actors would sharply reduce U.S. leverage over Tehran.
Gulf responses have diverged. The UAE is the only Arab Gulf state to publicly commit to joining an escort convoy to reopen the strait. Bahrain is lobbying the UN Security Council to authorize a multinational naval task force.
The Backlog Won't Clear Quickly
Even a full reopening of the strait won't quickly untangle global supply chains. The IMO reports roughly 2,000 vessels stranded by the closure, with at least 18 ships attacked since hostilities began. International shipping has rerouted through the Red Sea and Suez Canal.
Svein Ringbakken of the Norwegian Shipowners' Mutual War Risks Insurance Association cautioned that clearing the cargo backlog alone could take months — compounded by damage to energy and port infrastructure across the region. The IEA reports more than 40 energy assets have suffered serious or very serious damage, with QatarEnergy, Kuwait Petroleum, and Bapco Energies all declaring force majeure.
Hull and cargo insurance premiums have risen as much as 300 percent. Oscar Seikaly of NSI Insurance Group said war risk rates won't normalize until any security solution is genuinely permanent. Marco Forgione of the Chartered Institute of Export and International Trade put it plainly: rebuilding shipper confidence in the strait's safety "could take years."
