The way the world thinks of war changed forever in 1945. On July 16 in Alamogordo, New Mexico, America exploded the world's first atomic bomb, sending a huge mushroom-shaped cloud high into the sky. The Manhattan Project, which was used to end World War II, was mostly led by German and
             German-Jewish scientists, who had escaped from Hitler's Germany.
             In 1939, an American university professor named Albert Einstein wrote a letter to President Franklin D. Roosevelt, in which he outlined the possibility of using a
             nuclear chain reaction for a bomb. After reading the letter, Roosevelt began the Manhattan Project in 1943. Only a few people knew of the project, which was
             headed by J. Robert Oppenheimer, an atomic scientist from Germany.
             On August 6th and 9th of 1945, American planes dropped one atomic bomb each on Hiroshima and Nagasaki, Japan. The first bomb destroyed 80 percent
             of Hiroshima's buildings and killed about 80,000 people. The second bomb killed
             about 35,000 people. Japan surrendered to America after Nagasaki, but the
             people of Japan suffered failing health and horrible deaths for years afterward
             due to the effects of atomic radiation.
             Einstein later regretted his letter to Roosevelt, but he feared the Nazis would develop an atomic weapon and use it on America. Many scientific and military
             people involved with developing the bomb did not want it to be used, feeling it was immoral.
             The atomic bomb controversy started on August 6, 1945. The Atomic
             bomb was first used in combat as it was dropped on Hiroshima, Japan. The
             explosive power of the weapon was finally displayed. Within a few days,
             another bomb was dropped on Nagasaki, Japan. The atomic bomb was
             one of the mos...
