Query: An fascinating epic

This is a lucid, firsthand account by an instrumental post WW2 player. His was a generation that dealt with how the world would be put back together after the most devastating war in history. His service includes questioning Nazi prisoners as part of the US Strategic Bombing Survey (with his friend JK Galbraith), encouraging the formation of the Common Market (Jean Monnet), and guidance in the most contentious periods of the Cold War.The author's anecdotes are invaluable. An accomplished man, he recounts intimate views of luminaries in years of service matched only by his own admirable accomplishment. The latter included early principled opposition (and resignation) over the Vietnam War.This memoir is a pleasure to read: the author is a genuine American hero.
