Pete Hegseth estimates Iran war cost at $37.5 billion

Jul 21, 2026

Defense Secretary Pete Hegseth told Congress the Iran war has cost $37.5 billion, a figure critics call a "lowball." Hegseth made the statement while requesting nearly $88 billion in new funding. Independent analysts place the war's true cost over $100 billion. The conflict has resulted in at least 17 U.S. service member deaths. The debate over funding and costs comes amid reports that the war is "wildly unpopular."
