The Consequences Of The Manhattan Project

The Manhattan Project was to see if making an atomic bomb possible. The success of this project would forever change the world forever making it known that something this powerful can be manmade. The Manhattan Project’s success was something that had an impact on everybody involved since they helped create something with so much destructive power it could destroy a city within seconds.

The necessity of the atomic bombs have long been debated in America. Although they did contribute to stopping the war, Americans still wonder if murdering Japanese civilians was a necessary means to an end, or if it could have been avoided. Some people believe that the war would have ended without using the bombs. Others believe they were the sole purpose that the war finally ended. Many people were involved with bringing the bombs to fruition, such as the scientists, the government and military leaders, and the very teams that flew them to their targets. Then the President addressed the situation and American citizens spoke their minds. All of these people had their own thoughts on whether the bombs were needed. In this essay, the opinions on the atomic bomb’s necessity will be reviewed by presenting both the pros and cons from a variety of sources.

The pressing question still lingers: Was the United States justified in using the Atomic Bomb against Japan during WWII? World War II stands as the bloodiest and deadliest war of all time. It involved more than thirty countries and resulted in over fifty million civilian and military deaths. It lasted six years, beginning with Adolf Hitler’s invasion of Poland in 1939. As the Allied Powers (mainly the United States, Britain, and the Soviet Union) and the Axis Powers (Germany, Italy, and Japan) were in direct conflict with each other, many wonder if the cost of victory was too extreme. In late 1941, the process of creating the world’s first, most deadly weapon began. The production of the first atomic bomb was code named “the Manhattan Project.” After months of production, August 6, 1945, America dropped the “Little Boy” bomb on Hiroshima, wiping out ninety percent of the city. August 9, 1945, just three days after the devastation of the first bomb, America dropped the “Fat Man” bomb on Nagasaki. Dropping the atomic bomb on Japan was not necessary, nor justified in ending World War II. Due to the fact that America targeted heavily civilian populated cities (with limited military value), that Japan was in a position of surrender before the bomb was dropped, and the fact that the U.S. did not give enough time for Japan to process the devastation of the first bomb before the second in Nagasaki shows that America’s decision to drop the atomic bomb was entirely unjustified.

One of the most controversial and heavily scrutinized issue of the twentieth century was President Harry S. Truman’s decision to unleash atomic bombs on Hiroshima and Nagasaki in 1945. The motives behind Truman’s actions are shrouded in controversy as top military officials publicly denounced the use of such a disastrous weapon. There is overwhelming evidence supporting both sides of the decision, as historians are split in opinion. The United States had been using conventional bombing to try to push Japan over the edge to surrender, but with countless Japanese civilians loyal to their country, invading Japan proved to be more problematic than first thought. Harry S. Truman made the ultimate decision of dropping the atomic bomb in hopes that it would end the war, but the amount of casualties caused by it has historians questioning if it was morally right, “The bomb was unfortunate, but it was the only means to bring Japan to a surrender,” historian Sadao Asada states (Bomb 9). Truman’s decision to drop the atomic bomb on Hiroshima and Nagasaki were justifiable because they would ultimately lead to the end of the war and would demonstrate U.S. supremacy.

On May 1945, a long-awaited V-E Day finally came and brought an end to the war in Europe. But, the war in the Pacific was still continuing against Japan since they are being reluctant to surrender despite the continuous indiscriminate bombardments The United States began to consider about using the atomic bombs as the only way to end the war immediately. On the other hand, many argued that Japan’s staggering losses were enough to force Japan’s surrender. In the end, President Harry S. Truman didn’t hesitate to use this nuclear weapon and bombed Hiroshima and Nagasaki with only three days interval between the two bombing. As a result, Japan has surrendered, but if I were to make a decision, I haven’t used atomic bombs because it was unnecessary since Japan has virtually lost already.

Thesis: The research for the first Atomic bomb was done in the United States, by a group of the best scientists; this research was given the name of "The Manhattan Project". On Monday July 16th, 1945, a countdown for the detonation of the first atomic bomb took place near Los Alamos, New Mexico. This atomic bomb testing would forever change the meaning of war. As the atomic bomb was detonated it sent shock-waves all over the world. There was endless research done on the bomb in the United States. The research was called "The Manhattan Engineer District Project" but it was more commonly known as "The Manhattan Project."1 The Manhattan Project was brought by fear of Germany and it's atomic

The process of building the two atomic bombs was long and hard. The Manhattan project employed 120,000 people, and cost almost $2 billion. Although there were 120,000 Americans working on the project only a select group of scientist knew of the atomic bomb development. Vice president Truman never knew about the development of the bombs until he became president. The axis powers did not know what was going on with the development of the atomic bomb; there was a soviet spy in the project. The soviet spy was Klaus Fuchs, and he had become one of the few people who knew of the bombs.

On the clear morning of August 6, 1945 in Hiroshima, Japan, the world was hit with a total shock, that went down in history as a day for the history books. This day, the city of Hiroshima was blasted by the world’s first atomic bomb, which sent the grounds quaking, and leaving thousands dead. The debates for years since the bombing were having us all wonder if the attack was a military necessity or not. Considering both sides of the argument, it is clear to me that the bombing was the best plan for ending the world war. The use of the bomb saved more lives than it took.

America’s use of the atomic bombs on the Japanese cities also opened the door to other countries challenging them through their own use of nuclear bombs. Many have criticized that the atomic bomb was an act of “muscle flexing” due to the sheer power and destruction caused by the decision to drop the two bombs. (Nicholls, 67). Not only were these bombs a demonstration of the power that these nuclear weapons had, but they were a testament of power that the United States now held. Never before had a country surrendered in war without first being invaded, so the decision to drop the bomb and Japan's subsequent surrender were extremely significant (Baldwin, 39). These bombings didn’t just impact the Japanese, but the whole world and gave way to

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.

Throughout the Roosevelt administration and later through the Truman administration, it became clear that both had the distinct focus of ending World War II at the earliest possible time. This is a common theme identified throughout J. Samuel Walker’s Prompt and Utter Destruction. While some countries had put moderate effort into researching atomic power and how it could affect the war, the United States was the only country capable of putting full effort into researching and creating an atomic bomb that could be utilized during the war. Following warnings from scientists that informed Roosevelt of the possibility of the Germans making progress on their knowledge of nuclear energy, Roosevelt assigned a lofty and difficult project to the U.S. Army Corps of Engineers. This project soon became known as “the Manhattan Project” due to the engineer district that was formed to design and build this bomb being originally headquartered in New York. The Manhattan Project was established at a time in the war when the United States was uncertain of its outcome. After the first successful, self-sustaining nuclear chain reaction took place in a squash court at the University of Chicago, the idea of an atomic bomb became more feasible. However, while the idea became more feasible, the transition from experimental knowledge to designing an actual bomb was a huge step that involved many uncertainties and troubles. Although the Manhattan Project was formed during a period of uncertainty, the government had high hopes of the newly formed project, but despite these high hopes, the Manhattan Project faced seemingly insurmountable obstacles as it moved from experimental knowledge to designing the bomb, the most prominent being the design for the new technology and the role the bomb would play in the realm of global diplomacy.

By September, 1944, before Roosevelt’s death, the threat of a nuclear arms race and possible retaliation for the use of this weapon is already a point of concern. The Office of Scientific Research and Development’s memorandum to Secretary of War Henry Stimson outlines some of the dangers the United States and Great Britain face in continuing the secret development of this “art”. Realizing this technology in the hands of the Soviet Union or other countries, especially defeated enemies, would make highly populated cities especially vulnerable. They also concluded that there was a high possibility of a “major power, or former major power undertaking this development.” The threat of the Soviet Union or Germany developing this weapon was a

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 the morning of August 6, 1945, a B-29 bomber named Enola Gay flew over the industrial city of Hiroshima, Japan and dropped the first atomic bomb ever. The city went up in flames caused by the immense power equal to about 20,000 tons of TNT. The project was a success. They were an unprecedented assemblage of civilian, and military scientific brain power-brilliant, intense, and young, the people that helped develop the bomb. Unknowingly they came to an isolated mountain setting, known as Los Alamos, New Mexico, to design and build the bomb that would end World War 2, but begin serious controversies concerning its sheer power and destruction. I became interested in this topic because of my interest in science and history. It seemed an

Some regard the atomic bomb as “the thank God for the atom bomb”. This places God on the U.S. side and regards the bombs as our saving grace. This bomb forced the Japanese to surrender which in turn proved the U.S. to be the heroes who saved the American’s lives.1 The Americans intended on ending the war but did not expect to end it with such a large number of casualties. The results of the atomic bomb and how it effected the Japanese people both emotionally and physically will be addressed. “The bombs marked both an end and a beginning—the end of an appalling global conflagration in which more than 50 million people were killed and the beginning of the nuclear arms race and a new world in which
