Answer 2

Answer:

When the Nazis came to power in Germany, Einstein emigrated to the United States of America. Five years later, the discovery of nuclear fission in Berlin had American physicists in an uproar. Many of them had fled from Fascism, just as Einstein had, and now they were afraid the Nazis could build and use an atomic bomb. Einstein wrote a letter to Franklin Roosevelt to warn him of the consequences of the explosion of an atomic bomb.
