A report from the Pentagon's inspector general has given Congress its most detailed accounting yet of the war with Iran, laying out the strains on the military's weapons stockpiles and a price tag that has climbed into the tens of billions of dollars.

The report placed the cost of the conflict at a minimum of $42 billion. It also documented shortfalls in U.S. munitions, confirming that the pace of operations has drawn down inventories of certain weapons faster than they can be replaced. And it described the toll of Iranian strikes on American military bases, which the watchdog said inflicted significant damage.

Separately, reports indicated that a ship operating under U.S. contract, with American personnel aboard, was struck by Iranian forces. The inspector general's findings, together with these accounts, formed the backdrop for a contentious debate on Capitol Hill over whether and how the campaign should continue.

Much of that debate has unfolded within the Republican Party. A number of Republican lawmakers have voiced opposition to the war, a shift that several outlets connected to the approach of the midterm elections and to early attention on the 2028 nominating contest in Iowa. Representative Thomas Massie moved to impeach Defense Secretary Pete Hegseth over the conduct of the war, launching a formal effort that drew notice across the political spectrum.

The economic strain has extended beyond Washington. Analysts have pointed to a combination of higher oil prices and interest rate pressures stemming from the conflict, with one estimate putting the added burden at roughly $1,700 per household. Critics of the war's spending have emphasized the $38 billion in taxpayer costs cited in some accounts, framing it against the everyday financial pressures many Americans face.

The war has prompted a reassessment within the administration as well. Coverage described President Trump as charting a revised approach to Iran, though the specifics of that shift remain a matter of continuing reporting.

The inspector general's report catalogs the costs of the conflict in dollars and in weapons, but it does not resolve the political questions it has raised. Those questions now sit before Congress as the country moves toward the midterm elections.
