In a dramatic escalation of the three-week-old conflict, US President Donald Trump has given Iran a 48-hour window to reopen the Strait of Hormuz to global shipping or face the total destruction of its national energy infrastructure. The ultimatum, posted on Truth Social, specifies that the United States is prepared to “hit and obliterate” Iranian power plants, beginning with the country’s largest facilities, if the waterway is not fully cleared by 23:44 GMT on Monday. This hardline stance marks a sharp reversal from just 24 hours prior, when the President had suggested a potential “winding down” of military operations.
The threat comes in the immediate wake of Iran’s most destructive aerial assault on Israel since the war began on February 28. Two Iranian missiles bypassed defense systems to strike the southern towns of Arad and Dimona, wounding over 100 people. The strike on Dimona is particularly sensitive, as it sits near the site of Israel’s unacknowledged nuclear arsenal. Tehran characterized the attack as direct retaliation for a recent strike on its own Natanz nuclear facility. While Israel denied responsibility for the Natanz incident, it confirmed hitting a research center at a Tehran university allegedly linked to nuclear weapon components.
The closure of the Strait of Hormuz, which typically carries one-fifth of the world’s crude oil, has already sent global energy markets into a tailspin, with Brent crude surging past $105 a barrel. In response to the US ultimatum, the Iranian military warned that it would target American-linked energy and desalination plants across the region if its own infrastructure is attacked. Meanwhile, a coalition of international leaders—including those from the UK, France, Germany, and the UAE—issued a joint statement condemning the “de facto closure” of the strait and expressing readiness to participate in efforts to ensure safe passage.
As the conflict enters its fourth week, analysts at Chatham House suggest that Iran has shown unexpected resilience despite three weeks of heavy US-Israeli bombardment. While much of Iran’s senior leadership has been degraded, its ability to launch long-range strikes remains intact, evidenced by a recent (though unsuccessful) attempt to hit the US-UK base at Diego Garcia—some 4,000 kilometers away. With thousands more US Marines deploying to the Middle East and the 48-hour clock ticking, the region stands on the precipice of a full-scale industrial and energy war that could reshape the global economy for years to come.
