| 3 | 1945 | - 1945—1945: The Atomic Bombing of Hiroshima and Nagasaki
Having again stayed out of the initial stages of another worldwide conflict, the U.S. entered World War II on the side of the Allies following the Japanese attack on Pearl Harbor (December 1941). In August 1945, with the war in Europe over and U.S. forces advancing on Japan, U.S. Pres. Harry S. Truman ushered in the nuclear era by choosing to drop atomic bombs on Hiroshima and Nagasaki, Japan, in the hope that the terrible destruction unleashed would prevent an even greater loss of life that seemed likely with a protracted island-by-island invasion of Japan.
