President Donald Trump issued a curse-laden threat to Iran on Sunday, warning its leaders that unless they cave to his demand to re-open a critical shipping channel to U.S. vessels, the United States would launch an unprecedented attack Tuesday on Iranian civilian infrastructure.“Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran,” Trump wrote on his social media platform Truth Social. “There will be nothing like it!!! Open the F----- Strait, you crazy bastards, or you’ll be living in Hell – JUST WATCH! Praise be to Allah.”Iran has shut down access to the Strait of Hormuz – a critical shipping channel through which 20% of the world’s oil trade flows – to U.S.-aligned vessels in response to U.S.-Israeli attacks, sending oil prices soaring and rattling global stability. Trump first threatened to target Iranian energy plants last month, issuing Tehran a 48-hour deadline to re-open the Strait of Hormuz, but ultimately extended that deadline by five days, and again by another five days. The end of Trump’s second deadline extension is set to expire by the end of the day Sunday.
