A new report by the “Costs of War” project at Brown University’s Watson Institute for International Studies finds that nearly 200,000 people, including soldiers and civilians, were killed in the war in Iraq President George W. Bush launched 10 years ago.

The report also found that American taxpayers will ultimately spend roughly $2.2 trillion on the war, but because the U.S. government borrowed to finance the conflict, interest payments through the year 2053 means that the total bill could reach nearly $4 trillion.
