Democratic members of the US Senate Armed Services Committee have formally asked the Pentagon to disclose the full financial toll of President Donald Trump's military campaign against Iran, accusing the administration of concealing the true cost from taxpayers. In a letter sent Monday, the lawmakers pointed to what they described as “ongoing efforts to hide the true cost” of the conflict, which began in late February.
US Central Command (CENTCOM) has told Congress that the war has cost $43.6 billion as of September 3. But the senators argue that figure omits the expense of repairing damage from Iranian strikes on American bases and facilities across the Middle East. That damage estimate remains classified, although lawmakers have reviewed it.
Senator Elizabeth Warren of Massachusetts led the letter, joined by colleagues Mazie Hirono of Hawaii, Richard Blumenthal of Connecticut, Tammy Duckworth of Illinois, and Gary Peters of Michigan. They urged CENTCOM commander Admiral Brad Cooper to make the estimate public. “There is no rationale for classifying that cost estimate,” the senators wrote. “Our allies and our adversaries are, unfortunately, keenly aware of the extraordinary toll that this reckless war has taken on military readiness, and Congress and the public need this information to determine the steps necessary to recover from this debacle.”
Hidden damage and rising costs
According to a September report from the Pentagon's inspector general, Iranian strikes have damaged or destroyed hundreds of buildings and structures at US bases in eight Middle Eastern countries. The senators noted that despite a lack of transparency from the Department of Defense, “press reports of attacks, video footage, satellite images, and photos leaked to the media by active US service members have painted a dire picture of US bases and facilities damaged and destroyed by Iran.”
US officials and congressional aides have privately acknowledged that the damage is far more extensive than publicly admitted, with repair costs expected to run into the billions. The war has also taken a heavy human toll: more than 50,000 US troops have been deployed, at least 23 service members have died, and 865 have been injured. The Pentagon has repeatedly failed to disclose casualties, including troops hurt in Iranian strikes, and has moved some injuries out of its official tally.
Iranian civilians have suffered as well. The US-based Human Rights Activists News Agency (HRANA) reports at least 1,700 civilian deaths, while Iran's Health Ministry says more than 26,500 people were injured in the first 40 days. HRANA has documented over 2,200 injured children.
Independent analysts have long argued that the Pentagon's figures are incomplete. The Center for Strategic and International Studies estimated in June that the war had already cost roughly $40 billion, including $4 billion to $9.4 billion for base repairs—at a time when the Pentagon's public tally was just $29 billion. Stephen Semler of the Center for International Policy went further, arguing that the Pentagon was underestimating weapons replacement and ignoring military aid to Israel, which has joined the US in bombing Iran. He calculated the true cost at nearly $72 billion in the first 60 days, about three times the official estimate.
The financial burden extends beyond government spending. Mark Zandi, chief economist at Moody's Analytics, estimated last week that the war has cost the average American household nearly $2,000—$1,100 in higher energy prices, $540 in higher interest rates, and $360 in military costs. This comes as Trump's policies drive new inflation wave across US economy, adding to the strain on families.
Senator Warren said Monday that “Americans deserve to know how much of their money is being burned on Trump's war with Iran.” The demand for transparency comes amid broader concerns about the administration's handling of military engagements, including scrutiny over defense investments by Trump's sons and controversial remarks about bombing California.
As the conflict continues, the call for a true accounting is likely to intensify, with lawmakers and analysts pressing for clarity on both the human and financial costs of a war that shows no sign of ending.
