A new report by the Center for Strategic and International Studies (CSIS) estimates the US-Israeli war on Iran has cost the US $3.7 billion in its first 100 hours, or nearly $900 million per day. The high cost is largely attributed to the expenditure of over 2,000 munitions. Researchers Mark Cancian and Chris Park noted that most of these costs were not budgeted for, requiring the Pentagon to request additional funding. This could create political challenges for the Trump administration, especially given domestic concerns about cost-of-living, inflation, and rising gas prices. The CSIS analysis drew on Congressional Budget Office estimates, adjusting for inflation and operational tempo, due to limited specifics released by the Department of Defense.
