More than 2,860 American and allied troops have been killed in the Afghanistan war, which was launched in the wake of the 9/11 terrorist attacks to avenge the deaths of nearly 3,000 civilians. As many as 17,500 Afghan civilians have lost their lives in America’s second-longest war. The U.S. military intends to withdraw its combat troops from Afghanistan by the end of 2014, closing a chapter in American history that has largely been dropped from the headlines and the collective consciousness of the American people.

Stanford scholars and military experts, including Karl Eikenberry, Joseph Felter, J.B. Vowell, Viet Luong, Anja Manuel and Erik Jensen, talk about the lessons learned, the gains and losses and what to expect after the war formally comes to an end.
