eye of the enemy. One of these weapons was the Atomic Bomb‚ which was created through the Manhattan Project. The Manhattan Project was created in response to fears that German scientists were working on a weapon using nuclear technology since the 1930s. In a remote desert location near Alamogordo‚ New Mexico‚ the first atomic bomb was successfully detonated. It created an enormous mushroom cloud some 40‚000 feet high and ushered the world into the Atomic Age. In 1945 the United States had a decision
