The Wise Men showcases the first generation's smartest and best leaders, those whose flamboyant personalities and bold deeds brought order to the postwar chaos: Averell Harriman, a rambunctious diplomat who served as Roosevelt's special representative to Churchill and Stalin, Dean Acheson, the secretary of state who was more accountable than Truman for the Truman Doctrine and for General Marshall for the Marshall Plan, George Kennan, the author of Containment, Robert Lovett, the assistant secretary of war, undersecretary of state, and secretary of defence during the Cold War, John McCloy, one of the country's.
