Rome, 6 March (LaPresse) – According to an analysis by the Centre for Strategic and International Studies published on Thursday and reported by CNN, it is estimated that the first 100 hours of the US military campaign against Iran cost $3.7 billion, or more than $890 million per day. Less than $200 million of this total estimate are operational costs already included in the Pentagon's budget. In turn, the remaining $3.54 billion of the estimated cost “will likely require additional funding from the Department of Defence through a supplemental appropriation or another bill”, analysts said.
