As you learn more about the background and effects of these bombs, you will decide if the United States should continue to maintain atomic weapons.
When President Franklin D. Roosevelt died, his vice president of only four months, Harry Truman, assumed the presidency. The date was April 12, 1945, and FDR had served longer than any person before or since — 12 years! The 22nd amendment now guarantees that no president will be elected more than two terms, which is eight years. In May of 1945, Germany surrendered and the United States and the Allies put all their energy into defeating the Japanese.
Unbeknownst to Truman, there had been a secret undertaking to build an enormously destructive weapon. Read about The Manhattan Project from the American Museum of Natural History.
