Summary: The US Department of Defense inspector general estimated the war on Iran cost $33.4 billion between Feb. 28 and June 30, including just under $20 billion on munitions, and warned of “strategic inventory shortfalls” and industry replenishment bottlenecks. President Donald Trump dismissed the report, saying US ammunition stocks are “virtually unlimited,” while experts estimate it could take about three years to restore advanced missile and interceptor stocks.
