At the urging of a colleague, Einstein wrote a letter to the American President, Franklin D. Roosevelt, on 2 August 1939, in which he warned : “A single bomb of this type … exploded in a port, might very well destroy the whole port together with some of the surrounding territory.” His words did not fail to have an effect. The Americans developed the atomic bomb in a secret project of their own, and dropped it on the Japanese cities of Hiroshima and Nagasaki in August 1945.Einstein was deeply shaken by the extent of the destruction. This time he wrote a public missive to the United Nations. In it he proposed the formation of a world government. Unlike the letter to Roosevelt, this one made no impact. But ‘over the next decade, Einstein got ever more involved in politics – agitating for an end to the arms build up and using his popularity to campaign for peace and democracy.1.
