America has spent $6.4 trillion on wars in the Middle East and Asia since 2001, a new study says

American taxpayers have spent $6.4 trillion on post-9/11 wars and military action in the Middle East and Asia, according to a new study.

That total is $2 trillion more than the entire federal government spending during the recently completed 2019 fiscal year. The U.S. government spent $4.4 trillion during the fiscal year that ended Sept. 30, according to the Treasury Department.

The report, from the Watson Institute of International and Public Affairs at Brown University, also finds that more than 801,000 people have died as a direct result of fighting. Of those, more than 335,000 have been civilians. Another 21 million people have been displaced due to violence.
