You're confusing budgeted and actually spent. Wartime expenditures are not restricted to budget. For example. On paper, we budgeted only a few billion for wartime expenditures between 2001 and 2006, yet the actual money spent was in the trillions. My poli-sci teacher said in those 5 years, we spent enough money on the war to fund all healthcare and college for all of the USA for 10 years.
