As the US restarts war on Iran, is its weapons stockpile running low?

The US has expended half of at least four of its most critical munitions since its war on Iran began on February 28. President Trump is scheduled to speak at the US Army War College, but the dwindling stockpile could leave the US less formidable against China. Attacks resumed after an April ceasefire and a June memorandum of understanding, with heavy strikes on Iran's military sites.
