After we conquered the enemy at Normandy, the Nazi forces came to a halt and surrendered after Adolf Hitler committed suicide in his bunker. However, the Japanese had different ideas, after defeating them in multiple battles, they still would not surrender, so the United States had to take drastic action to stop them from killing more troops. That’s where the Manhattan Project comes in, scientists during all of the preceding events had been working to produce a bomb that was powered by the science of splitting nuclei within certain elements (Encyclopedia of U.S. History 950). The project was started in secret by the president of the time, Franklin Roosevelt. This continued unknown to the public and even for a brief period, the next president, Harry Truman. After the Secretary of Defense, James Forrestal, informed Mr. Truman about their secret, he was very cautious and down to earth about his decision to use it.
The Manhattan Project was the United States answer to the growing Nazi forces. America was fearful that Germany might develop an atomic bomb (Encyclopedia of U.S. History 950). The atomic bomb was based off the science of nuclei splitting. This is also known as nuclear fission, using the

The two scientists that convinced Roosevelt to change the atomic energy to a more militarized form were the Chairman of the Office of Scientific Research and Development (OSRD), Dr. Vannevar Bush and the Chairman of the National Defense Research Committee (NDRC), Dr. James B. Conant (Groves xvi). The man behind the purpose was Dr. Arthur H. Compton, a Nobel Prize winner for his new discovery, the Compton Effect, which was the way that cosmic waves react, was the head scientist of the Chicago campus study team (Groves xvi). He stated that the purpose of the research was to build understanding required to design and construct and operate a plant for the transformation of uranium to plutonium. Once Roosevelt came to the conclusion that this weapon had to be created before Hitler’s forces beat him to it, he was the one that gave the project much needed funding and support to continue. Luckily, FDR did not have to use it against Nazi Germany. But when the next president, Harry S. Truman, took the office and all the responsibilities of the Manhattan Project, he decided to use two against Japan after many verbal warnings and demands for them to surrender. Since they had carried out a devastating attack on the U.S. Navy and after the Nazi forces had already surrendered. As pilot Enola Gay flew over the small island of Japan he released the first nuke, the Fat Man, onto the Japanese town

    The Manhattan Project was established during World War II. The federal government gave $6,000 towards research for creating an atomic bomb. In the article, The first atomic bomb test is successfully exploded, it says, “But early in 1942, with the United States now at war with the Axis powers, and fear mounting that Germany was working on its own uranium bomb, the War Department took a more active interest, and limits on resources for the project were removed.”3 This meant the War Department put aside the Manhattan Project and prioritized destroying the hydroelectric plant. At the end of World War II, Germany already surrendered and that is when the United States were successful in the Manhattan Project.…

    The research and development cost incurred from the Manhattan Project were high, and in need of justification. The American people were still enraged from the attack at Pearl Harbor (20) and the loss of “loved ones in the last few days and weeks of the war” (94). Up to this point, the barbarities of the Japanese people were well known more than that of the Germans, as the terrors of the Holocaust was only made known to the public after the surrender of the Nazi’s (20). The U.S. Government was also “fueling hatred” (20) among Americans by releasing information about the abuse of American prisoners by the Japanese (20.

Not only did America have the strongest army, navy, and air force, but also the atomic bomb, a secret weapon capable of such vast destruction that no one had a defense against it (Capio 65).…

    Before the outbreak of World War II, American scientist were worried about the research of nuclear bombs in Nazi Germany. Hence, the U.S government began to conduct and fund their own researches on atomic weapon developments. This was called ‘The Manhattan Project’ which was a top secret facility in which the research and development of atomic weaponry created the first nuclear weapon. The morning of August 6th, 1945, represented a significant change in history in which a Boeing B-29 Superfortress, Enola Gay, dropped the first atomic bomb ‘Little Boy’ on Hiroshima which immediately destroyed the city along with approximately 146,000 people. Three days later on August 9th, the second atomic bomb, ‘Fat Man’ was dropped on the city of Nagasaki…

    The atomic bomb was used in WW II. In 1939, the world’s scientific community discovered that German physicists had learned the secrets of splitting an uranium atom (“The Manhattan Project”). In late 1941, the American effort to design and build an atomic bomb received its code name -- the Manhattan Project, which included scientists David Bohm, Leo Szilard, Eugene Wigner, Otto Frisch, Rudolf Peierls, Felix Bloch, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fachs, and Edward Teller (“The Manhattan Project”). The chief among the people who unleashed the power of the uranium atom was Robert Oppenheimer, who oversaw the project from conception to completion to make sure that nothing would go wrong (Bellis). There were two bombs that were dropped miles apart in different cities, Hiroshima and Nagasaki, in Japan (“The…

    During WWII, President Franklin Delano Roosevelt approved the development of the atomic bomb, a project that became known as the Manhattan Project, out of fear that the Nazis would try to build and use a nuclear weapon. After FDR’s death, President Truman inherited the most powerful weapon in the history of mankind and was left with the choice of using it or not. Undoubtedly, his decision changed the world in so many ways, and is largely thought and taught that dropping the atomic bombs on Hiroshima and Nagasaki was necessary to end the Pacific War. Conversely, there were a number of alternatives the United States could have considered to avoid exposing our world to nuclear weapons while still triumphing in a Japanese agreement to an unconditional…
