U.S. President Donald Trump has issued a renewed warning to Iran, declaring that any Iranian attack on ships in the Strait of Hormuz will be met with a response twenty times stronger. Speaking to reporters aboard Air Force One on Wednesday night, Trump said this would now be the rule: for every Iranian strike, the United States would retaliate with twenty times greater force.

Trump dismissed the idea of diplomatic talks with Iran, calling them a waste of time and expressing doubt about Iran’s ability to honor any agreement. He claimed that the United States had already won the war against Iran and asserted that Iran had little left. According to Trump, Iran wants a deal but behaves irrationally and appears out of control.

When asked whether the United States was heading toward a full-scale military conflict with Iran, Trump said he did not know but insisted that the U.S. had many ways to win and had already achieved military victory.
