Iran war cost hits $38bn, forecast to rise $3bn a month, CBO says The six-month-old US war on Iran has cost $38bn so far, and that amount is projected to rise by $3bn a month, Congress's nonpartisan bookkeeper reported on Tuesday, as the Trump administration searches for ways to end the war and reopen the vital Strait of Hormuz.
