Mideast War Strains US Government Debt

The U.S. national debt has surged to nearly $38.8 trillion as of early March 2026. This figure is projected to hit $54 trillion within the next decade, a forecast made before accounting for the full costs of the expanded military campaign against Iran. Recent military actions in the Middle East have added billions to federal expenditures. Operations since October 2023, including strikes against Iran's nuclear facilities and countering Houthi militants, are estimated to have cost between $9.65 billion and $12.07 billion through September 2025. This includes the first-ever combat use of 30,000-pound "bunker buster" bombs in Iran. These new war costs are layered on top of a defense budget that already exceeds spending on Medicare. The FY2026 defense appropriations bill provides a base of $838.7 billion, which is over $10 billion more than the Pentagon requested, reflecting Congressional additions for shipbuilding and other programs. Historically, U.S. national debt sees a significant surge following major military conflicts. The debt level after the Civil War, for instance, was more than 42 times what it had been before the conflict began. The conflict's economic pressure extends to trade, with proposed secondary tariffs threatening to punish third-country trade with Iran. This strategy aims to erode Tehran's export earnings by forcing it to absorb the cost of the tariffs, potentially straining an economy already under heavy sanctions. This combination of direct military outlays and economic warfare measures comes as interest payments on the national debt are already compounding. The cost to service the U.S. debt for the current fiscal year now surpasses the entire defense budget.
