Philip Taubman and his brother William have written what the publisher Norton is calling "McNamara at War: A New History." It's a full life biography of former Secretary of Defense Robert Strange McNamara. "It's a portrait of a man at war with himself," according to the authors. "It's riven with melancholy, guilt, zealous loyalty, and profound inability to admit his flawed thinking about Vietnam before it was too late." William Taubman, seven years older than his brother at 83, is an emeritus political science professor from Amherst College. Brother Phil spent 30 years with the New York Times and is an author of several books. Learn more about your ad choices. Visit megaphone.fm/adchoices
