Grey is the color of truth. So observed Mac Bundy in defending America’s intervention in Vietnam. Kai Bird brilliantly captures this ambiguity in his revelatory look at Bundy and his brother William, two of the most influential policymakers of the Kennedy and Johnson administrations. It is a portrait of fiercely patriotic, brilliant and brazenly self-confident men who directed a steady escalation of a war they did not believe could be won. Bird draws on seven years of research, nearly one hundred interviews, and scores of still-classified top secret documents in a masterful reevaluation of America’s actions throughout the Cold War and Vietnam.
