Journalist David Finkel talks about war and the ongoing effect it has on those who fight. Finkel is a staff writer at the Washington Post and the author of two books about the war in Iraq, from the point of view of those who fought in it. "The Good Soldiers" follows the lives of soldiers on the front lines in Baghdad. In his latest book, "Thank You For Your Service," Finkel revisits these solders' lives after coming home.
