Defence Secretary tells Congress expenses could climb further as lawmakers question long-term sustainability of military spending

The United States Department of Defense has revealed that the ongoing conflict with Iran has already cost an estimated $37.5 billion, underscoring the steep financial toll of prolonged military engagement in the Middle East.

Speaking before Congress, the U.S. Secretary of Defense said the figure reflects a broad range of expenditures, including troop deployments, combat operations, logistics, weapons systems, intelligence activities, and support for personnel on the ground.

He cautioned that the overall cost is likely to increase if the conflict drags on, noting that sustained operations continue to stretch resources and demand additional funding.

Despite the mounting expenses, the Pentagon maintained that the U.S. remains firmly committed to safeguarding its strategic interests, backing its allies, and preventing further instability across the region.

The disclosure has intensified debate in Washington, where lawmakers are raising concerns about the long-term economic implications of the conflict. Several members of Congress are calling for stricter oversight and a clearer strategy to justify continued military spending.
