Trump's Iran War Has Already Cost Taxpayers $28 Billion -- And Counting

$28 Billion and No Exit Strategy

President Trump's war with Iran has cost American taxpayers $28 billion in just over a month, according to retired Marine Colonel Mark Cancian, a senior adviser at the Center for Strategic and International Studies. That figure covers deployed forces, thousands of munitions fired, and losses to bases and aircraft -- and it does not include the long-term costs of replenishing weapons stockpiles or treating wounded service members.

The price tag keeps climbing. On day 39 of the conflict, Trump renewed threats to destroy every bridge and power station in Iran if the country refuses to reopen the Strait of Hormuz -- a threat that would constitute war crimes under international law and drive military costs even higher.

A Single Rescue Mission Cost Up to $500 Million

The administration has framed the war as necessary to prevent Iran from obtaining nuclear weapons, but the costs are staggering even by the standards of America's post-9/11 forever wars. A single operation -- the rescue of a downed American airman -- is estimated to have cost between $200 million and $500 million when accounting for lost equipment.

Currently, about 7,000 U.S. ground forces are deployed in the region. Cancian said expanding ground operations -- such as seizing islands in the Strait of Hormuz to force it open -- would increase costs and likely result in significant casualties and equipment losses. "Opening the straits using military force would be a major combat operation on its own," he told NPR.

Weapons Shortages Will Take Years to Fix

A significant portion of the $28 billion has gone to munitions, including high-end precision weapons like Tomahawk missiles and Patriot antimissile systems. The problem: the U.S. military has burned through these weapons faster than defense contractors can replace them.

"It takes years to replace them," Cancian said, noting that production capacity is limited and U.S. allies are competing for the same weapons. The Pentagon also wants to expand munitions stockpiles in preparation for a potential conflict with China in the western Pacific -- meaning Iran war costs will compete with other strategic priorities for years to come.

Sending the Bill to Your Kids

None of this is paid for. The war is not in the federal budget, and the Trump administration has not proposed raising taxes or cutting other spending to cover the costs. Instead, the $28 billion is being added directly to the national debt.

"We've made a decision as a society that we are going to put these kinds of programs on our credit card, increase the debt," Cancian said. "Unfortunately, across the board, we've made a decision that we're going to spend today, and we're going to send the bills to our children and grandchildren."

That is a bipartisan failure, Cancian noted, pointing to deficit spending under both the Trump and Biden administrations. But Trump's decision to launch an optional war with Iran -- rather than pursue diplomatic solutions or accept the status quo -- represents a choice to saddle future taxpayers with tens of billions in debt for a conflict with no clear endgame.

What Are We Getting for $28 Billion?

When asked whether the spending justifies the war, Cancian declined to take a position. "Depends on your view of the war," he said. "If you believe that we cannot allow Iran to have a nuclear weapon, this was probably the moment to take action on that. On the other hand, the problem might have been managed, and in which case, going to war was not worthwhile."

Translation: even defense analysts cannot articulate a clear rationale for why this war needed to happen now, or what success looks like.

The war continues with no resolution in sight. Trump's threats to destroy civilian infrastructure suggest he is willing to escalate further rather than negotiate. And every day the conflict drags on, the bill grows -- paid for by borrowing against the future while Trump claims credit for being tough on Iran.
