“The cost to the US for war on Iran is $3.7 billion in the first 100 hours”
A 2020 report by the Center for Strategic and International Studies estimated initial military operations against Iran would cost approximately $3.7 billion for the first 100 hours. This estimate reflects direct operational costs including munitions, fuel, and immediate personnel expenses, but does not include long-term costs, sustained operations beyond the initial period, or reconstruction expenses. The estimate was based on a specific limited strike scenario rather than a full-scale war.
