The U.S. Department of Defense requires an additional $800 billion to fund the ongoing Iran war and other non-war expenditures, according to Deputy Defense Secretary Stephen Feinberg. He disclosed this during a phone call with U.S. lawmakers earlier this week, as reported by The Wall Street Journal. A supplementary budget proposal is expected to be sent to Congress within days, including allocations for defense as well as non-defense sectors such as agriculture and disaster relief. Neither the Pentagon nor the White House has commented on the report, and Reuters could not independently verify it.

In April, a Pentagon official told Reuters that approximately $250 billion had already been spent on the Iran war, marking the first official cost estimate. The total cost of the conflict, launched jointly by President Donald Trump and Israel on February 28, remains unclear. A previous $200 billion funding proposal faced strong opposition in Congress.

Budget debates continue as the White House defends Trump’s proposed $1.5 trillion annual military budget, which reflects Republican priorities ahead of the November midterm elections.
