American taxpayers have spent $1.46 trillion on wars abroad since September 11, 2001.
The Department of Defense periodically releases a “cost of war” report. The newly released version, obtained by the Federation of American Scientists Secrecy News blog, covers the time from the September 11th terrorist attacks through mid-2017.
The Afghanistan War from 2001 to 2014 and Iraq War from 2003 to 2011 account for the bulk of expenses: more than $1.3 trillion. The continuing presence in Afghanistan and aerial anti-ISIS operations in Iraq and Syria since 2014 have cost a combined $120 billion.
