Hegseth tells Senate Iran war cost is $37.5 billion, far below reported Pentagon request

Defense Secretary Pete Hegseth told a Senate panel on July 21, 2026, that the Iran war has cost $37.5 billion so far. That is well below the more than $200 billion the Pentagon asked Congress for, as a U.S. official described to Reuters in March 2026. Gen. Dan Caine testified alongside Hegseth.
