The U.S. war with Iran has already cost American taxpayers at least $37.5 billion, according to Defense Secretary Pete Hegseth. Speaking before the Senate Appropriations Committee alongside Joint Chiefs Chairman General Dan Caine, Hegseth confirmed the figure during a hearing that coincided with the completion of the 11th consecutive night of U.S. airstrikes on Iranian military targets.
A War Escalating in Cost and Scope
At the same time, the White House warned it is weighing a strike against one of Iran’s most heavily fortified underground nuclear facilities — underscoring how what was initially framed as a limited operation to protect shipping and curb Iran’s nuclear program has evolved into a broader conflict with mounting military, economic, and human costs.
The $37.5 billion figure includes not only munitions and operational expenses but also projected costs such as troop meals and logistical support through the end of the fiscal year. However, defense analysts and senators cautioned that the true total is likely far higher — factoring in precision-guided munitions used in repeated strikes, losses of advanced radar and air defense systems, damage to U.S. military infrastructure, expanded force deployments across the Middle East, and ongoing protection of commercial vessels in the Persian Gulf.
Pentagon Asks for Nearly $70 Billion in Additional Funding
The Trump administration is now requesting nearly $70 billion in supplemental funding for the Pentagon — yet has offered no clear timeline for ending hostilities. The request has drawn bipartisan concern on Capitol Hill.
Democratic Senator Chris Coons said he wasn’t surprised by the $37.5 billion figure — and voiced suspicion that the real cost is already greater. Republican Senator John Kennedy demanded “straighter answers” from the Defense Department, stressing that the administration must explain to the public why the U.S. entered the war, how it plans to exit, and how it intends to prevent Iran from acquiring nuclear weapons.
Democratic Senator Dick Durbin echoed those concerns, stating that Hegseth and Caine failed to justify either the current expenditures or clarify how the additional funds would be spent.
The hearing highlighted growing unease among lawmakers — even within the president’s own party — over the war’s open-ended nature, its rapidly escalating price tag, and the absence of a coherent strategy for de-escalation or diplomatic resolution.
