The great scientist, Albert Einstein wrote two letters. One was a letter written to the President of the United States of America and the other one was written to the United Nations. The purpose of writing this letter was to warn the two of them about the destruction that one atom bomb could make and about the fact that the Nazis had the ability to make an atom bomb. It could destroy the whole world. So in his letter, he wanted to warn the President and the United Nations.
