scopi bellici dell' energia:la bomba nucleare

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.
