Graveyard of Empires: A Conversation with Ambassador Nathan Sales

What went wrong in Afghanistan, and who is to blame? Is America safer today than on September 10, 2001? What lessons should the leaders of America's foreign policy draw from the war in Afghanistan? Ambassador Nathan Sales is a nonresident senior fellow at the Atlantic Council, the former U.S. State Department Coordinator for Counterterrorism, and former acting Under Secretary of State for Civilian Security, Democracy, and Human Rights. He joins the show to answer these questions and others.
