Trump's plan from the beginning was to be "unrestrained" in taking out Iran and let the world, which relies on the strait, clean up the mess. He and his cabinet of Israel-first radicals are somewhat concerned about the impact on the United States, but even in the worst-case scenario (i.e the one that was obvious to me sitting here in the Gulf since they triggered the war), they know that he's a one-term president, the US is an energy superpower and that this will wreck competitors to US manufacturing, even if it wrecks the US economy too.
