At this September 2011 event,  New America Foundation President Steve Coll, New America National Security Studies Program Director Peter Bergen, and Foreign Policy magazine Editor in Chief Susan Glasser looked back on the 9/11 attacks and the way they shaped – and continue to impact – our lives today.
