Iran will move to shut down the entire Strait of Hormuz if U.S. President Donald Trump follows through with his threats to hit Iranian energy facilities, the nation’s Revolutionary Guards said on March 22.

Trump said that the U.S. military would “hit and obliterate [Iran’s] various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST” if Tehran doesn’t fully open the Strait of Hormuz “without threat” within 48 hours of his social media post Saturday evening.
