US President Donald Trump stepped up calls to reopen the vital Strait of Hormuz, saying warships will “hopefully” be sent to the area near Iran’s coast to help commercial vessels sail through safely.

His comments on Truth Social — which didn’t provide a timeline — came hours after he ordered a strike on military sites on Kharg Island, from which Iran exports almost all its oil, upping the ante in a Middle East war that’s raged for more than two weeks and shows little sign of easing.

The president said military facilities on the Persian Gulf island had been “obliterated,” adding that he chose not to hit oil infrastructure “for reasons of decency.” He threatened to do just that should Iran “do anything to interfere with the Free and Safe Passage of Ships through the Strait of Hormuz.”

“Many Countries, especially those who are affected by Iran’s attempted closure of the Hormuz Strait, will be sending War Ships, in conjunction with the United States of America, to keep the Strait open and safe,” he wrote in his latest post. He gave little detail beyond saying he hoped China, France, Japan, South Korea and the UK would also send warships.

He stated that even though Iran’s military was “already destroyed 100%,” it was “easy” for Tehran to continue threatening ships with drones, mines and short-range missiles. The US, he said, “will be bombing the hell out of” Iran’s shoreline to try to counter that.
