PROVIDENCE, R.I. [Brown University] — Nearly 10 years after the declaration of the War on Terror, the wars in Afghanistan, Iraq, and Pakistan have killed at least 225,000 people, including men and women in uniform, contractors, and civilians. The wars will cost Americans between $3.2 and $4 trillion, including medical care and disability for current and future war veterans, according to a new report by the Eisenhower Research Project based at Brown University’s Watson Institute for International Studies. If the wars continue, they are on track to require at least another $450 billion in Pentagon spending by 2020.

The group’s “Costs of War” project, which involved more than 20 economists, anthropologists, lawyers, humanitarian personnel, and political scientists, provides new estimates of the total war cost as well as other direct and indirect human and economic costs of the U.S. military response to the 9/11 attacks. The project is the first comprehensive analysis of all U.S., coalition, and civilian casualties, including U.S. contractors. It also assesses many of the wars’ hidden costs, such as interest on war-related debt and veterans’ benefits.

Catherine Lutz, the Thomas J. Watson Jr. Family Professor of Anthropology and International Studies at Brown University, co-directs the Eisenhower Research Project with Neta Crawford, a 1985 Brown graduate and professor of political science at Boston University.

Among the group’s main findings:

The U.S. wars in Afghanistan, Iraq, and Pakistan will cost between $3.2 and $4 trillion, including medical care and disability for current and future war veterans. This figure does not include substantial probable future interest on war-related debt.

More than 31,000 people in uniform and military contractors have died, including the Iraqi and Afghan security forces and other military forces allied with the United States.

By a very conservative estimate, 137,000 civilians have been killed in Iraq and Afghanistan by all parties to these conflicts.

The wars have created more than 7.8 million refugees among Iraqis, Afghans, and Pakistanis.

Pentagon bills account for half of the budgetary costs incurred and are a fraction of the full economic cost of the wars.

Because the war has been financed almost entirely by borrowing, $185 billion in interest has already been paid on war spending, and another $1 trillion could accrue in interest alone through 2020.

Federal obligations to care for past and future veterans of these wars will likely total between $600-$950 billion. This number is not included in most analyses of the costs of war and will not peak until mid-century.

Simon Lee/Released “This project’s accounting is important because information is vital for the public’s democratic deliberation on questions of foreign policy,” said Lutz. “Knowing the actual costs of war is essential as the public, Congress and the President weigh the drawdown of troops in Afghanistan, and other areas including the deficit, security, public investments, and reconstruction.”

“There are many costs and consequences of war that cannot be quantified, and the consequences of wars don’t end when the fighting stops,” Crawford said. “The Eisenhower study group has made a start at counting and estimating the costs in blood, treasure, and lost opportunities that are both immediately visible and those which are less visible and likely to grow even when the fighting winds down.”

The Eisenhower Research Project is a new, nonpartisan, nonprofit, scholarly initiative that derives its purpose from President Eisenhower’s 1961 farewell address, in which he warned of the “unwarranted influence” of the military-industrial complex and appealed for an “alert and knowledgeable citizenry” as the only force able to balance the often contrasting demands of security and liberty in the democratic state.

The Costs of War has released its findings online, at www.costsofwar.org, to spur public discussion about America at war.
