U.S.-led wars cost 940,000 civilian lives and $2.3 trillion.

Since 2001, U.S.-led wars have caused an estimated 940,000 civilian deaths and cost trillions of dollars, with the Afghanistan war alone costing $2.3 trillion. The ongoing conflict with Iran, which began in 2026, has already cost at least $12.7 billion in its first six days, averaging roughly $1 billion per day due to expensive munitions. Experts and veterans warn that prolonged engagements create long-term instability and significant burdens on service members and society.
