Having guided the nation through the worst economic crisis in its history, Franklin Delano Roosevelt by 1939 was turning his attention to a world on the brink of war. The second part of Roger Daniels' biography focuses on FDR's growing mastery in foreign affairs. Relying on FDR's own words to the American people and eyewitness accounts of the man and his accomplishments, Daniels reveals a chief executive orchestrating an immense wartime effort. Roosevelt had effective command of military and diplomatic information and unprecedented power over strategic military and diplomatic affairs. He simultaneously created an arsenal of democracy that armed the Allies while inventing the United Nations intended to ensure a lasting postwar peace. FDR achieved these aims while expanding general prosperity, limiting inflation, and continuing liberal reform despite an increasingly conservative and often hostile Congress. Although fate robbed him of the chance to see the victory he had never doubted, events in 1944 assured him that the victory he had done so much to bring about would not be long delayed.
