US War Cost $2.4Trillion

War May Cost $2.4 Trillion Over Decade

The wars in Iraq and Afghanistan could cost as much as $2.4 trillion through the next decade, the nonpartisan Congressional Budget Office said. The White House brushed off the analysis as "speculation."

The estimate was the most comprehensive and far-reaching one to date. It factored in costs previously not counted and assumed that large number of forces would remain in the regions.

According to analysis, the U.S. has spent about $604 billion on the wars, including $39 billion in diplomatic operations and foreign aid.

If the U.S. were to reduce the number of troops deployed to Iraq and Afghanistan to 75,000 six years from now, it would cost the U.S. $1 trillion more for military and diplomatic operations and $705 billion in interest payments to pay for the wars through 2017.
