Iran war has cost US $37.5bn so far, Hegseth says, as Pentagon seeks billions more

What Happened

US Defense Secretary Pete Hegseth testified before the Senate Appropriations Committee that the war with Iran has cost the United States $37.5 billion as of the hearing date, an increase from the last estimate of $29 billion on 12 May. Hegseth requested $87 billion in additional funding, with $67 billion directed to Middle East operations, warning that without it, training would be curtailed and critical shortfalls would threaten pay and munitions. The hearing was repeatedly interrupted by anti-war protesters. The Pentagon also confirmed the deaths of Sgt Michael Emmanuel Swinton in Iraq and Pfc Isabella Gonzales and 1st Lt Tyler Feehan in Jordan. President Trump, in a social media post, stated that 18 US service members had died in the conflict since 28 February. Hostilities resumed after the collapse of an April ceasefire, with the US conducting a 10th consecutive day of strikes on Monday and Iran retaliating against US and allied targets.

Why It Matters

The $37.5 billion cost figure and urgent funding request reveal the escalating financial burden of the US-Iran war, which has seen a resumption of hostilities after a failed ceasefire. The political clash in Congress—between Republicans supporting a 'generational investment' in military strength and Democrats challenging the war's cost and legitimacy—reflects deepening domestic division over the conflict. With US casualties mounting and anti-war protests disrupting official proceedings, the war is becoming a central and contentious issue in US politics, potentially affecting Pentagon readiness and broader Middle East stability.

Watch For

Congressional action on the $87 billion supplemental request, which faces delay as the House adjourns Thursday and both chambers do not jointly return until September. Monitor further US and Iranian military operations, especially strikes and retaliations, and any new casualty reports that could influence public opinion and legislative decisions. Also watch for any diplomatic efforts to restore the ceasefire or de-escalate, given the breakdown in April.
