On December 7 of 1914, in Pearl Harbor, Hawaii, American was just awakened. They did not know Japanese battle planes were flying in. Before the soldiers even knew what was happening a torpedo was launched and explosion erupted through the Harbor. This was the beginning of Americas involvement in World War II. Before this attack, America had not been a part of the war. Over 1,000 American soldiers lost their lives that day and America would not let this attack go unanswered. This was a major turning point in world history.
The bombing of Pearl Harbor and the development of the atomic bomb, led to the bombings of Hiroshima and Nagasaki. It marked the first time a nuclear warfare was used. These two great bombings marked the end of World War II in 1945. The bombing of these cities affected political and social health of the world.
The whole world changed when the atomic bomb was created. The start of the Manhattan Project was a wartime effort to design and build the first nuclear weapons. It began in August of 1942. The Manhattan Engineer District was the official name of the project. The Commanding Officer of the Manhattan Project was General Leslie R. Groves. The project cost two billion dollars.
The Potsdam Declaration was an ultimatum that was communicated to Japan issued by the United States, Britain, and Nationalist China. The Declaration called for the government of Japan to," proclaim the unconditional surrender of all Japanese armed forces." Japanese leaders decided to reject the Potsdam Declaration and vowed to continue fighting.
Tadaka Kuriboyashi experienced the atomic bomb when she was a child. "The six months I spent in Tsutsuga village on the northern part of Hiroshima prefecture still remains, vividly in my memory even after so many years. It was difficult to imagine what happened in those days for young people." (www.A-BOMB/RERF/setB-4.html).
Many atomic bomb survivors remember where they were at the exact time of the explosion.
