US President Donald Trump has promised strikes on Iran’s power plants and bridges on Tuesday, restating his threat to attack civilian infrastructure if the Strait of Hormuz isn’t reopened.In an expletive-laden post on Sunday morning, Trump promised the “crazy bastards” would be “living in Hell” if the waterway isn’t opened to marine traffic.Trump had previously threatened strikes two weeks ago, but extended the deadline for Iran to reopen the waterway twice, claiming there were positive signs in negotiations with the Iranians. But there have been few public signs of progress in a diplomatic off-ramp to the war.
