The United States’ military campaign against Iran has cost an estimated $3.7 billion in its first 100 hours, with most of the spending not previously budgeted, according to new research by the Washington-based think tank Center for Strategic and International Studies (CSIS).
The analysis, conducted by researchers Mark Cancian and Chris Park, estimated that the conflict, now in its seventh day, has cost Washington about $891.4 million per day, largely driven by the use of large volumes of munitions and the deployment of advanced systems including stealth bombers.
