Trump to Iran: Open Hormuz in 48 hours or U.S. bombs power plants

Friction point: On Friday afternoon, a little more than 24 hours before Trump's new threat, the president said he was considering "winding down" the war without resolving the closure of the Strait of Hormuz.

• If he does walk away without reopening the strait, the U.S. would be leaving other countries to clean up an economic quagmire.
• Roughly one-fifth of the world's oil depends on the Strait of Hormuz. With it choked off, the U.S. national average for a gallon of gas hit $3.94 Sunday morning, according to AAA, up more than a dollar from a month earlier.

What he is saying: "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 wrote on Truth Social.

The other side: Iranian Parliament Speaker Mohammad Bagher Ghalibaf, one of the country's top civilian leaders, responded with a threat of his own.

• "Immediately after the targeting of power plants and infrastructure in our country, vital infrastructure and energy and oil facilities across the region will be considered legitimate targets and will be destroyed irreversibly, and oil prices will rise for a long time," he wrote on X.
