  • Secretary of War Pete Hegseth stated that the Department of War will share more formal accounting of the costs of the Iran war “when it’s relevant.”
  • In response to a question from House Democratic Caucus Chair Pete Aguilar, Hegseth stated that the ceasefire with Iran remains in effect and that negotiations with the Iranian regime are ongoing to reach a settlement.
  • He also said the U.S. could revive Project Freedom if necessary, a day after President Donald Trump said he was considering the move.

The U.S. war on Iran has cost about $29 billion so far, according to a senior Pentagon official, representing an increase of $4 billion compared to an estimate provided at the end of April this year.

“At the time of the testimony, it was $25 billion. But the Joint Staff team and the Comptroller team are constantly looking at their estimates, and so now we think it’s close to $29 billion,” Jules Hurst, Under Secretary of Defense (Comptroller), Department of War, told lawmakers during a House Armed Services Committee hearing on Tuesday.

Hurst said the updated estimate reflects the revised repair and replacement costs for equipment, as well as general operational costs to keep personnel on duty.

Hegseth Says Formal Numbers Will Be Shared ‘When It’s Relevant’

Secretary of War Pete Hegseth stated that the Department of War will share more formal accounting of the costs of the Iran war “when it’s relevant.”

In response to a question from House Democratic Caucus Chair Pete Aguilar, Hegseth stated that the ceasefire with Iran remains in effect and that negotiations with the Iranian regime are ongoing to reach a settlement.

He also said the U.S. could revive Project Freedom if necessary, a day after President Donald Trump said he was considering the move.

“The theory of the entire case is to prevent Iran from having a nuclear weapon, and if that has to be done kinetically and militarily, the Department of War is locked and loaded and ready to do that,” he said.

Bernie Sanders Says Iran War Could Cost Over $1 Trillion

Meanwhile, Senator Bernie Sanders stated in a post on X last week that the Iran war could cost the U.S. more than $1 trillion, calling the Trump administration’s estimates a lie.

“This war could cost over $1 trillion—thousands of dollars for every household in America. Invest in housing, education, and health care—not illegal and unconstitutional wars,” Sanders said, while calling for an end to the Iran war.
