Wednesday September 12, 2012

PROVIDENCE, R.I. (AP) -- A Brown University study that aims to put a price tag on the U.S. response to 9/11 has found that the wars in Iraq and Afghanistan and other counterterrorism efforts have cost more than 300,000 lives and $4 trillion.

The university calls its "Costs of War" study the most comprehensive ac counting of the financial and human costs of American counterterrorism efforts. It brings together the work of economists, political scientists, anthropologists and others.

The study says the conflicts have led to the deaths of more than 6,500 U.S. soldiers and an estimated 180,000 civilians. It says 7.4 million people have been displaced and many of the economic costs are buried in multiple budgets and have yet to be counted.

The findings are continually updated and are available at

The study doesn’t detail whether the military re sponse to 9/11 saved Am erican lives by reducing the threat of terrorism.

The project is being done by Brown’s Watson Institute for International Studies.
