Trump gives Iran 48-hour ultimatum to reopen Strait of Hormuz or face strikes on power plants | 21 March 2026 | President Donald Trump issued a 48-hour ultimatum to Iran on Saturday, warning the U.S. would strike its power plants if the Strait of Hormuz is not reopened. “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!” Trump said in a post on Truth Social. The president’s threat represents a notable escalation in rhetoric as tensions surge over the strategically vital waterway. Earlier Friday, Trump ripped NATO on Truth Social as “cowards,” saying they “complain about the high oil prices they are forced to pay, but don’t want to help open the Strait of Hormuz.”
