Einstein wrote a letter to the president of america,Franklin D to warn them that Nazis had developed an atomic bomb

to tell the harmful effects of atomic bomb and advise him not to use them

Einstein feared that the germans under the rule of nazi had developed the atomic bomb and could misuse it. So he wrote a letter to the president of USA to warn him of this development.

Einstein wrote a letter to the American President, Franklin D. Roosevelt on 2 August 1939 in which he tried to warn the American President about the effects of this bomb and also wanted them to make other bomb that could utilize it's potential of destruction.

=> According to Einstein, bombing of Hiroshima and Nagasaki was unnecessary. Einstein played an important role in the making of atomic bomb but the Americans developed the atomic bomb in a secret project of their own and dropped it on these two Japanese cities. He was later depressed and felt guilty by the extent of destruction. He also wrote a long letter for the formation of World Government in order to stop the destruction caused by the nuclear weapons.
