The $4 Trillion War on Terror: New at Reason



James Bovard – May. 22, 2016

The war on terror has cost at least $4 trillion since 2001.

The biggest costs in the war on terror come from foreign wars. Between late 2001 and 2014, the U.S. government spent roughly $2.6 trillion in Afghanistan, Pakistan, and Iraq—not just for warfare but also for reconstruction, foreign aid, and health care for veterans, according to the Watson Institute for International and Public Affairs at Brown University.

The Pentagon spent an additional roughly $100 billion to thwart terrorism overseas in 2015, according to the National Priorities Project, a nonprofit budget watchdog group. And it will likely spend a similar amount this year.
