Former Defense Secretary James Mattis offered a sobering take Monday on the Strait of Hormuz, criticizing the Trump administration for what he saw as a failure to think strategically about Iran. "We're in a tough spot, ladies and gentlemen, and I can't identify a lot of good options," the retired Marine general told attendees at the CERAWeek by S&P Global conference. If President Trump declares victory and pulls back the U.S. military, Iran "would now say we own the Strait." "I think that you could see a tax for any ship going through " something completely unsustainable in the international market," Mattis said.
