“Since 2001, the Defense Department, State Department and U.S. Agency for International Development have spent or appropriated between $934 billion and $978 billion, according to an inflation-adjusted estimate calculated by Neta Crawford, a political science professor and co-director of the Costs of War Project at Brown University.
Those figures do not include money spent by other agencies such as the CIA and the Department of Veterans Affairs, which is responsible for medical care for wounded veterans.”
