Fact Sheet: Costs of the Trump Administration’s War in Iran

Center for American Progress  |  Allison McManus, Andrew Miller, Ariana Sharghi, Dawn Le, Emily Gee

President Donald Trump’s military conflict in Iran has generated massive economic and strategic liabilities, costing the United States between $34 billion and $100 billion while driving domestic fuel prices up by 30 percent. This escalation has severely strained American households, which face an average financial burden of $1,100 from inflated energy, borrowing, and consumer costs.

The sudden outbreak of hostilities forced the Pentagon to rapidly redeploy critical assets, including missile defense batteries in South Korea, to reinforce the Middle Eastern theater. This reallocation of high-demand munitions has simultaneously depleted stockpiles earmarked for Ukraine, exposing deep vulnerabilities in Western industrial capacity. Concurrently, the suspension of oil sanctions on Russia to stabilize energy markets handed Moscow a $2.3 billion windfall in May 2026, while Beijing exploited the unilateral action to position itself as a responsible mediator. With the collapse of the June 17 ceasefire, these compounding tolls are projected to intensify.

Comment

The redeployment of THAAD missile defence batteries from South Korea to the Middle East exposes the acute capacity limits of American global air defence coverage. By prioritising immediate deterrence against Iranian missile strikes, Washington accepts heightened vulnerability in the Indo-Pacific, potentially inviting opportunism from Pyongyang or Beijing. This geographic reallocation demonstrates how localised conflicts rapidly disrupt the Pentagon's global force management model, forcing zero-sum choices between active combat zones and long-term deterrence commitments.
