The world had not fully recovered from the horror of World War I or the anguish of its catastrophic aftermath, the Great Depression, before an even greater war commenced. The Third Reich of Adolf Hitler threatened to dominate all of Europe and, as the physicist Albert Einstein rushed to bring to the attention of President Franklin Roosevelt, the limitless destructive power of the atom was well within the reach of Nazi Germany. World War II, Revised Edition presents the complete story of America's war in Europe and in the Pacific, from Pearl Harbor to the Normandy invasion to the Japanese surrender aboard the USS Missouri. Vivid photographs, illustrations, and maps, along with helpful research features, make this book an invaluable addition to any classroom or library. Also included in this new edition is a chapter devoted to the military innovations seen during this massive war.
