THE SECOND WORD WAR IN USA When World War II broke out in Europe, Roosevelt promised to keep the USA out of the war. However, on December 7th 1941, Japan bombed the American naval base at Pearl Harbour, in Hawaii. This event forced Roosevelt to declare war. The USA quickly joined the British-Soviet alliance against Japan, Fascist Italy and Nazi Germany. During the war, Roosevelt worked closely with the leaders of allied powers, Churchill and Stalin, but he died just before the end of the war. The new president was Harry Truman. When the war ended in Europe, Japan refused to surrender. Truman made a big decision: on August 6th 1945, America dropped an atomic bomb named ‘Little Boy’ on Hiroshima in Japan. It destroyed the city and killed thousands of people. Japan still refused to surrender. Three days later, on August 9th, a second bomb, nicknamed ‘Fat Man’, was dropped on Nagasaki. Again the devastation was horrible. Six days later Japan surrendered to American forces.

durante la seconda guerra mondiale gli stati uniti promuosero il progetto manhattan che consisteva nel greare una bomba basata sulla recente scoperta della scissione degli atomi di uranio
