The atomic bomb was the result of the manhattan project, an enormous undertaking by the U.S. government to exploit the fission process for military purposes, by way of a bomb with incredible destructive powers.

After the initial attack Truman warned the Japanese that they must surrender or the U.S. would bomb other sit...
