Report: US costs of Iraq, Afghan wars top $900 bln

US military operations, including the Iraq and Afghanistan wars, have cost $904 billion since 2001 and could top $1.7 trillion by 2018, even with big cuts in overseas troop deployments, a report said on Monday.

A new study released by the nonpartisan Center for Strategic and Budgetary Assessments, or CSBA, said the Iraq conflict's $687 billion price tag alone now exceeds the cost of every past US war except for World War II, when expenditures are adjusted for inflation. (Reuters)
