The U.S. defense secretary said the Iran war has cost about $37.5 billion so far, including military pay, operations, and costs projected through the end of the fiscal year. That figure follows a prior estimate near $29 billion in mid-May, as the Pentagon seeks roughly $67 billion in supplemental funding to cover unanticipated costs. Independent analyses and CSIS put total spending higher, with estimates approaching $40 billion when all costs are included. The hearings occurred amid ongoing tensions and renewed actions in the Strait of Hormuz, including blockades and discussions of a prolonged conflict. President Trump, as current president, has signaled support for a large defense budget and war funding, while critics warn of the risks of another “forever war.” Protests and partisan debate framed the funding package as a major GOP priority and a test of the administration’s willingness to back a costly military campaign.
