The president’s 48-hour ultimatum tied possible U.S. strikes to Iran reopening the Strait of Hormuz.
WASHINGTON, DC — President Donald Trump said Sunday that if Iran did not agree to a deal within 48 hours, “we’re blowing up the whole country,” escalating an already volatile standoff over the Strait of Hormuz and raising fears of broader U.S. military action in the Middle East.
The remark mattered immediately because it came as U.S. and Israeli operations against Iranian targets were already underway, oil markets were reacting to the blocked waterway, and diplomats at the United Nations and in regional capitals were still trying to prevent a wider war. Trump’s statement also sharpened attention on whether Washington was preparing attacks on Iranian infrastructure beyond military sites, a step that legal experts, aid groups and foreign governments have warned could bring severe civilian consequences.
Trump’s threat was delivered in a phone interview Sunday as he pressed Iran to accept terms he said could be settled in “days, not weeks.” He linked the ultimatum to the closure of the Strait of Hormuz, one of the world’s most important oil shipping lanes, and signaled that little would be off limits if Tehran refused. The rhetoric built on comments he had already made about targeting bridges and power plants and on an Easter message warning of “hell” if the strait stayed closed. By Monday and Tuesday, he had gone further, publicly suggesting that unless Iran backed down by 8 p.m. Eastern, the consequences could be catastrophic. Trump framed the pressure campaign as an attempt to force a rapid settlement after weeks of fighting, saying he believed Iran would eventually yield. Iranian officials, however, rejected the deadlines and said the country would not negotiate under threat.
Administration officials and outside analysts say the backdrop to Trump’s remark is a fast-moving conflict that widened after U.S. and Israeli strikes on Iran in late February and Iran’s retaliation across the region. Trump has described a risky rescue mission for a downed U.S. F-15E crew inside Iran as proof of American reach and resolve. He praised U.S. forces for extracting the two airmen after a complex operation involving multiple aircraft, intelligence support and heavy fire. At the same time, the White House has offered only limited public detail about what specific military options remain under review. Trump has said bridges, power facilities and other infrastructure could be targets if Iran keeps the strait closed. What remains unclear is whether the administration has approved a timetable for such strikes, how narrowly it would define military necessity, and whether allies would support a campaign that reaches well beyond battlefield targets.
The wider context has made Trump’s words especially consequential. The Strait of Hormuz handles a major share of global oil shipments, and its closure has sent energy markets higher while putting pressure on governments far from the Gulf. Fighting has already hit transportation links, industrial sites and energy facilities in Iran. Reports from the region describe mounting civilian fear, damage to basic services and growing uncertainty over whether the next phase of the war will focus on military command sites or on infrastructure that supports daily life. That distinction matters under the laws of war and in practical terms for millions of people who depend on electricity, water systems, roads and fuel distribution. Trump has argued that overwhelming pressure can force a deal. Critics say the language risks normalizing attacks that could cripple civilian life even if Iran’s leadership remains in place.
Legal and diplomatic pressure has intensified as Trump’s deadline approached. The International Committee of the Red Cross warned that the rules of war must be respected in both words and actions, a statement widely read as a response to the growing talk of strikes on civilian-dependent infrastructure. U.N. officials and legal scholars have similarly warned that attacks on power plants, bridges and desalination or water-related systems could violate international humanitarian law unless they serve a concrete military purpose and expected civilian harm is limited. At the United Nations, the Security Council prepared to vote on a reduced resolution aimed at reopening the strait, but major powers were divided over how strongly to respond and whether to authorize anything beyond defensive maritime coordination. Iran, for its part, has said any additional attacks on its infrastructure would draw a severe response. As of Tuesday, no public announcement showed that Tehran had accepted Trump’s terms, and the administration had not released evidence of a formal deal.
The scene around the crisis has reflected both alarm and hardening positions. In Iran, officials and residents have signaled defiance as strikes and threats mounted, with public messaging focused on sovereignty and endurance. In Washington, Trump and his allies have presented the ultimatum as a blunt but necessary show of force designed to reopen a strategic chokepoint and end the confrontation on U.S. terms. Some Republicans have echoed that argument. Democrats and humanitarian advocates have answered that the president’s language was reckless and could make diplomacy harder at the very moment it is most needed. The gap between those views has widened with each new statement. For now, where things stand is this: Trump has publicly tied a narrow diplomatic demand to the possibility of devastating military escalation, Iran has refused to bend to the deadline, and the next major milestone is whether the White House announces new strikes or a breakthrough after Tuesday’s 8 p.m. Eastern cutoff.
