World War II: America's First Atomic Bomb

Superior Essays
In World War II, America expanded military tactics and extremity of weapons that would change the world forever. As early as the beginning of the war, brilliant minds such as Albert Einstein advised President Truman on creating a nuclear bomb. (“Nuclear Bomb”) This bomb was meant to be the most powerful weapon ever used in military history. The Manhattan Project was the codename for America 's research in trying to create the world 's first atomic bomb. Once America succeeded in this discovery, two bombs were dropped on Japan to end the war. The exploration of new and more dangerous military weapons like the atomic bomb was justified because it demonstrated the power of the United States, ended the war and utilized the time and money spent …show more content…
Some historians say that it was a cruel and unnecessary action but evidence points to the fact that it was a necessary tool in ending the war. They also believe that a final invasion on Japan would have resulted in their surrender but a study performed by physicist, William Shockley, proves differently. It was estimated that it would cost “1.7-4 million American casualties, including 400,000-800,000 fatalities, and five to ten million Japanese deaths.” (Miller) These numbers point to the fact that it would have generated more deaths by not using the bomb than in actually using it. Lives of children and people of Japan were going to be at risk in either way that American handled the situation. Not using it would mean potentially another year or two of war and in Truman 's opinion the war had already put enough ache on the lives of Americans. In the historical book, Prompt and Utter Destruction: Truman and the Use of Atomic Bombs, Secretary of War Henry “Stimson went on to recommend that the bomb be used against Japan in order to end the war as soon as possible and avoid the huge numbers of American casualties that an invasion would incur. An assault on the Japanese islands, he told the president, "might be expected to cost over a million casualties to American forces alone." (Walker 3) If an important leader such as the Secretary of War is recommending the use of the bomb, it becomes clear that it was necessary to use on Japan. According to the Scientific Panel in June of 1945 composed of Oppenheimer, Fermi, Compton and Lawrence, they found that there was no “acceptable alternative to direct military use” of the bomb. These were some of the most brilliant minds existing in America at the time, discluding the much accredited Albert Einstein. They were very skilled and knowledged in their fields and some of Truman’s most trustworthy advisors during World War II.

    It had appeared that the Japanese were not going to surrender the way America wanted them to. Of course a big reason why the bomb was used is that if Japan would have been invaded, the death toll could have potentially reached half a million or more instead of the hundreds of thousands that were killed by the atomic bomb. It is said that if the war had continued the amount of American lives lost could have greatly diminished the amount that was killed by the bombs. It is hard to tell what could have really happened but it is certain that if the war had continued so would the loss of…

    the Dropping the atomic bomb was the only correct decision for the United States because of casualties being less than what they would have if America had invaded, the brutality of Japanese towards the American POW, and the importance of intimidating Stalin.

    One theory is that dropping the atomic bomb was absolutely necessary. There are several key points to this argument, that the Japanese would never surrender unconditionally, that war would drag on, that a land invasion would be costly, long, deadly, and the bomb was needed specifically to end the war swiftly and with as few casualties as possible. “At the time, there was a wide consensus in support of the decision to strike among the members of the committee. Stimson was very adamant that the bomb be used”.⁴ A key part of the problem was the belief that the Japanese would never surrender.…

    Truman’s choice to drop the bomb on Japan was justified since it helped in ending the war rapidly.

    Some American scientists disagreed with the idea of using the bombs on military targets and on large populations, etc. They believed that it’d be better to test them out on a demonstration such as an uninhabited island. Japan did not surrender until two bombs had been dropped not one. So the second one was necessary to end the war.…

    The bomb itself showed the potential of America's scientific and technological advancement due to the incredible amount of damage and lives it took in one explosion. Despite this, the bomb could actually save lives because of how fast it took them. A single blast can take over 80,000 lives and annihilate about 10 square miles of land. With this power, it would stop Japan from sending in more soldiers again us and pretty much kill themselves about it, and less American soldiers would be wounded or killed by fighting. America could quickly wipe out Japan without so much as to send a single soldier, compared to how slow and grueling constant air raids would be despite the fact they took more lives.…

    Tens of thousands were killed in the bombing, naming it inhumane. The bomb’s purpose was not to harm innocent people, its purpose was to first get the Japanese government to surrender, if didn’t surrender then attack cities that help create war material. Innocent lives could have been saved if they evacuated the cities as warned. The dropping of the two atomic bombs saved millions of lives of Americans and the lives of Japaneses. The Japanese government plan was to invade America in a land invasion, causing up to 5 to 10 million casualties of Japanese fighters.…

    First, I investigated the sources that were against the use of the bomb before the bomb was dropped including the intentions behind the bomb, and concerns from the Interim Committee . Then I looked at the evidence against the bomb after the bomb was dropped, including Henry Stimson’s concerns, and the horrific loss of Japanese life due to the bomb. It is interesting to see the difference between the worries before the bomb and after the bomb. The first document I looked at was Dropping the Atomic Bomb was Neither Necessary Nor Justifiable by Gar Alperovitz. In his essay he argues one of the reasonings for the use of the bomb was to scare the Soviets and to prevent an invasion of the Red Army in Manchuria.…

    The use of the Atomic Bomb was both necessary and justified as it immediately ended World War II, solidified the United States as a superpower, and contained the germinating powers of Japan and Russia. The use of the Atomic Bomb on Hiroshima and Nagasaki immediately ended World War II and stopped the continuation of catastrophic and widespread violence in Japan. The Japanese had an audacious outlook on their offense throughout the duration of the war. It was suggested by Admiral William E. Leahy that, “The Japanese were already defeated and ready to surrender”(Source 2).…

    The Decision to Drop the Bomb During the summer of 1945, things were looking pretty grim for Imperial Japan, as they were the last axis power left and had been under constant firebombing for the United States, President Truman chose to drop two atomic bombs, one on Hiroshima on August 6th and one on Nagasaki on August 9th. Since before either of the two bombs had been dropped, it has been debated whether or not it was the right decision. Truman stated that the bombs were dropped to save American lives, but many argue over the government’s other motives at the time. Many bring up valid points over why the bomb should not have been dropped and that the government public justification for dropping the bomb was based off of false information, but ultimately the motivation behind dropping the bomb, hidden by the government or not, outweighs the reasons for not dropping the bomb.…

    Roosevelt warning of a calamitous event if the United States failed to develop an atomic bomb before Germany. By mid-July of 1939, Germany had advanced its findings of isotope separation, which could of been used to achieve a “fast- neutron chain reaction in U-235, the basis of the atomic bomb.” This was shocking to the group of physicists, and as a result they reported to the White House and spoke with Alexander Sachs, who was an informal advisor to President Roosevelt and was aware of the nuclear atomic research in Germany. Being aware of the potential hazards that could occur if German research went on, Sachs and the group of physicists decided that if the prestigious scientist Albert Einstein was involved in their efforts that Roosevelt would be more likely to take notice of the escalating dilemma. On August 2, Leo Szilard and Edward Teller succeeded in getting Einstein to sign the letter urging the President to support an atomic weapons research program.…

    This extraordinary letter written by Albert Einstein to President Franklin Delano Roosevelt was written on August 2nd, 1939 to inform the President on the potential plans of the creation of a nuclear bomb. The letter was an official document written by Einstein and mailed out to the white house in Washington D.C. During this time, World War Two was on the brink of being unleashed, and many physicists were studying the effects of Uranium in possible preparation for the war. Furthermore, Albert Einstein was in America working with other physicists on the puissant bomb during the time of the formation of this letter. Einstein letter is filled with multiple opinions and options to President Roosevelt, such as, the latest findings on uranium, his feelings towards the use of uranium, his ideas on having a “middle-man” between the physicists and government officials, and the lack of…
