President Donald Trump issued a 48-hour ultimatum to the Iranian government on Saturday, demanding a diplomatic resolution or the total reopening of the Strait of Hormuz.
The directive, announced from the White House, marks a critical turning point in the month-long conflict known as Operation Epic Fury.
"They have 48 hours to make a deal or open the Strait of Hormuz," President Trump stated during a morning briefing with national security officials.
The President warned that failure to comply would result in a massive military escalation, stating that "all hell will reign down on them" if the waterway remains obstructed.
The Strait of Hormuz, a vital chokepoint for global oil, has been effectively closed to most traffic since hostilities began in late February.
The Iranian Revolutionary Guard has maintained a blockade, asserting control over the corridor despite repeated U.S. and Israeli airstrikes.
Secretary of State Marco Rubio emphasized that the administration remains open to a "fair" agreement but that patience for "delay tactics" has ended.
"The global economy cannot be held hostage by a regime that refuses to adhere to international law," Rubio told reporters at the State Department.
Secretary of Defense Pete Hegseth confirmed that U.S. naval assets are prepared to enforce the reopening of the strait if diplomacy fails.
The ultimatum follows reports that Iran’s leadership requested a ceasefire, though the White House maintains that any reprieve is contingent on free navigation.
