“I still can’t get his voice out of my head,” George Packer writes of the late diplomat Richard Holbrooke. “One day I know it will start to fade, along with his memory, along with the idea of a life lived as if the world needed an American hand to help set things right.” The Atlantic’s George Packer sits down with Walter Isaacson to discuss the life and ambitions of Richard Holbrooke, the diplomat behind the Dayton Accords that ended the Balkan wars, and to talk about the passing of an era of American supremacy.
