FILE - In this Thursday, May 3, 2012 photo provided by the Tennessee National Guard, Ashley Edens leans on the casket of her husband, Spc. Jason Edens, in Smyrna, Tenn. Spc. Edens was killed April 15, 2012 during combat in Afghanistan. Eleven years after the U.S. began battling to rid Afghanistan of al-Qaida and the Taliban, the war has ebbed from the headlines. The question of just how to end it is barely mentioned in the speeches of this year's presidential campaign. Polls find most Americans just want it over. (AP Photo/The Tennessee National Guard, Capt.
