The Atomic Bomb

In the 1930’s and the 1940’s there was a change in American leadership. Having this change not only changed the outcome of the war that we were currently in, but how the rest of the world would view our country after the war. The decision that Harry Truman was forced to make on the choice to drop the atomic bomb or to attempt more land invasions was a choice that shaped the outcome of the war. There were major influences and side effects from the dropping of the atomic bomb and what it did to the country of Japan. Having the option and the weight of the moral decision weighing on Truman’s shoulders about what decision should be made, he was the only one who was capable of making the decision that shaped the outcome of the war. Having dropped the bomb on Japan, as a statement of power and a means to an end in a form was the only way that American lives could have been spared as comparing that to the lives that would have been lost in a land invasion. Knowing what the issues with the bomb was; one has to look at the moral issues, the results of the incident, and also how it played in the rest of the development of the world.

With the start of World War II the race for the first atomic bomb started. With Germany under Hitler’s reign, the Nazis began separating uranium to form the first atomic bomb to control the world. The push for the United States build the first atomic bomb began with this knowledge. With the help of several scientists the United States succeeded in building the atomic bomb first. Two atomic bombs were used; a uranium bomb on Hiroshima and a plutonium bomb on Nagasaki. Along with the many deaths were six stages of A-bomb illness which includes acute stages, atomic bomb trauma, A-bomb radiation illness, radiation blood injury at lethal dosage, blood injuries, and secondary radiation illness. Seven unhealed scars were also an effect of the atomic bombs that includes keloids, A-bomb cataracts, leukemia, cancers, chromosome changes, exposure in utero and microcephaly, and genetic surveys. Regulations and guidance were set in place soon after the bombings to protect the people of the world based on the information that was gathered and it has changed over the years based on the new information that was learned. With the use of the atomic bombs in World War II, a lot of pain and suffering was caused, but a great deal of information was learned to help protect future generations from radiation.

The Manhattan Project was created out of the fear of their current enemy, Germany of making the first atomic bomb and using it in the war. The current President of the United States was Franklin Roosevelt. It was seen that Germany was making great advances in the war which worried many. But the people who were very worried were three prestigious scientists. Leo Szilard, Eugene Wigner, and Edward Teller who were Hungarian scientists who immigrated to the United States during the war. Szilard and the other scientists wished to advocate for the start of a program that put all efforts into making an atomic bomb. But of course they were very intelligent on how to get their cause across seriously. “Though the three men, particularly Szilard, were well known

Even before the outbreak of War, the United States was concerned with a fascist regime in Europe researching in nuclear weapons. In retaliation, the United States began to fund an atomic weapon development program which became known as “The Manhattan Project” led by J. Robert Oppenheimer. Over the next several years, the Manhattan project started obtaining key materials such as Uranium-235 and Plutonium and testing prototypes until they reached a working model (Coroner).

On August 2, 1938, in the heat of World War II, Albert Einstein, a physicist born in Germany, sent a letter to Franklin Delano Roosevelt, the 32nd president of the United States. The letter suggested America to build an atomic bomb before the Nazi Germany does. However, it took more than two months for the letter to reach Roosevelt. On October 19, 1938, Roosevelt agreed, replying, “I found this data of such import that I have convened a Board … to thoroughly investigate the possibilities of your suggestion regarding the element of uranium” (“President Roosevelt's response to Dr. Einstein”). As a result, America held a secret program, code named Manhattan Project, and started to build new, destructive weapons in a laboratory in Los Alamos,

The Manhattan Project was a research and development project that produced the first nuclear weapons during World War II. The Manhattan project was the invention of the first two nuclear bombs, Fat man and little boy. These two bombs were dropped on Japanese islands to end World War II.

The origins of the Manhattan Project go back to 1939, when Hungarian-born physicist Leo Szilard, who had moved to the U.S. in 1938 to conduct research at Columbia University, became convinced of the feasibility of using nuclear chain reactions to create new, powerful bombs. German scientists had just conducted a successful nuclear fission experiment, and based on those results, Szilard was able to demonstrate that uranium was capable of producing a nuclear chain reaction. Szilard noted that Germany

During the 20th century, specifically the year 1945, the United States of America had two atomic bombs that the commander and chief, and president at the time, Harry Truman, knew about. President Truman plan was to drop the bombs on two of Japans cities, Hiroshima first and then Nagasaki. Truman’s plans went accordingly, which to this day leads to a very controversial topic on whether or not dropping the atomic bombs was a good or bad thing. There is evidence and reasoning to back up both claims, in which everyone is entitled to their own opinion. However, in my opinion, I believe the choice of Harry Truman to drop the two atomic bombs was the right choice because it saved lives, helped end the war faster, and it was merely the only choice for the sake of the American soldiers.

The Manhattan Project was assembled when “in 1939 the world’s scientific community discovered that German physicists had learned the secrets of splitting a uranium atom.” (US History 1) This caused many people to panic and it was later agreed that this issue of the Axis powers developing nuclear weaponry should be brought up to the United States, which could perhaps stop the Germans from causing unspeakable destruction to much of the world. Scientists Albert Einstein and Enrico Fermi, who both were living in the United States after leaving their previous countries to escape from either persecution or just leave the fascist state that Italy was currently in. Fermi was the scientist that went to Washington in order to express his concerns about this development of the splitting of the uranium atoms but not many others shared his concerns. Once Fermi

On December 7, 1941, the Japanese launched a bombing attack on the American naval base in Pearl Harbor. This attack on the U.S. brought America into World War II. One Japanese general commented “I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve.” (Yamamoto) Japan’s surprise attack on the U.S. created a much larger enemy than they intended. After the attack the U.S. embarked on a bloody and hard fought campaign through the pacific, which ultimately led to the Dropping of two atomic bombs and the surrender of Japan. Although many lives were lost the American decision to drop the bombs was justified because it ended the war quickly, saved american lives, and showed the world the power of the U.S. The Pacific War was a long and drawn out process that was moving very slowly for the United States, was struggling to pull off any major naval victory and from the mistakes made of the U.S. basically leaving the Japanese unattended while they were fighting the Germans in Europe. The American decision to drop the Bombs was justified because the U.S. wanted to end the war quickly and not to have a costly invasion of the Japanese Homeland as well as showing power to the world. Truman wanted to end the war as fast as he could because we had been in conflict for 4 years now and the American forces were very weary and tired of war, the U.S. dropped it for the other reason of

On August 2, 1939, just before the beginning of World War II, Albert Einstein wrote to then President Franklin D. Roosevelt. Einstein and several other scientists told Roosevelt of efforts in Nazi Germany to purify uranium-235, which could be used to build an atomic bomb. It was shortly thereafter that the United States Government began the serious undertaking known then only as "The Manhattan Project." Simply put, the Manhattan Project was committed to expediting research that would produce a viable atomic bomb.

e Manhattan Project was a research and development project that produced the first nuclear weapons during World War II. It was led by the United States with the support of the United Kingdom and Canada. People basically were offered job in this new city called Oak Ridge, Tennessee. They weren't told much other than they were helping their country by working here.

The Manhattan Project arose in the United Sates due in part to the scientific breakthrough by the Nazi’s allowing them to split the uranium atom. Over several years, the Manhattan Project developed a nuclear weapon with the capability to end the Pacific War. The Manhattan Project was in the hands of both president Roosevelt and Truman, each impacting its development course to suit the given situation of the time period. The Manhattan Project and the actions of President Truman are highly controversial in terms of inhuman methods utilized, though they resulted in both expenditures and lives being spared in the process. From 1942 to 1946, the development of the Manhattan Project and the decision by President Harry S. Truman to drop the Atomic

Since the beginning of the construction of the atomic bomb in 1942, 100,000 scientists have worked on the Manhattan Project. During its time, the Manhattan Project was the largest collaborative scientific achievement recorded. It was the largest collective scientific effort ever undertaken. The project required thirty-seven different work sites, thirteen university laboratories, and many esteemed scientists. The Manhattan Project was also considered one of the most secret military projects in history. On August 6th, 1945, as US B-29 bomber plane dropped the first atomic bomb over the city of Hiroshima, the bomb approximately killed 80,000 people upon detonation. Another bomb would eventually be dropped on the city of Nagasaki only three days later, this time killing 40,000 people. After hearing the news of the bombs being dropped, a wave of joy and satisfaction swept across the nation. This reaction seemed to be shared between white and black citizens. Most Americans did not see an issue with using the bomb because it was used as revenge for Pearl Harbor. Meanwhile, African Americans were hoping to be rewarded with equality due to their roles in the war. African Americans viewed the war as an opportunity to display their loyalty to the United States of America. The African American reaction to the bomb was very different from the majority of America’s reaction, rather than celebrating the revenge against the Japanese they took pride in their role leading to the

In 1941, The United States began an atomic bomb program called the “Manhattan Project.” The main objective of the “Manhattan Project” was to research and build an atomic bomb before Germany could create and use one against the allied forces during World War II. German scientists had started a similar research program four years before the United States began so the scientists of the “Manhattan Project” felt a sense of urgency throughout their work (Wood “Men … Project”).
