Read about Japan's attack on Pearl Harbor, which shocked the United States into joining the war in Europe; the destruction of the Japanese cities of Hiroshima and Nagasaki, the first targets for unleashing the new atomic bomb; and D-Day, the invasion that gave the Allies a way into Europe to free the countries captured by Hitler.
