...The Bombing of Hiroshima and Nagasaki: History's Great Miscalculation On August 6, 1945, a new step in technological warfare was taken when the first atomic bomb was dropped on the city of Hiroshima, Japan. The impact of the bomb alone killed at least 66,000 people.1 This was an event that would not soon be forgotten in history. The Americans, who knew the devastating effects of their new weapon, still chose to use it rather than an alternative means to peace. Many people still argue whether or not it was necessary when Japanese surrender was considered to be a matter of time. Historians also dispute whether the campaign was a morally justified objective. This phrase alone brings up many interesting questions. Can killing thousands of innocent people ever be considered "justified"? Considering these circumstances, the dropping of the atomic bomb on Hiroshima and Nagasaki was not militarily or morally justified. In 1939 Franklin Roosevelt, the President of the United States received a verysignificant letter from the famous physicist, Albert Einstein.2 Contained in this letter were details concerning the importance of nuclear research with regards to gaining the upper hand in the war. Roosevelt agreed and approved $6,000 in initial funding. Many scientists began realizing the importance of nuclear fission and in 1940 The National Defense Research Committee was formed. This group's purpose was to oversee research and provide more funding. Many of the world's best physicists...

...Kristen Chinn Physics II Dr. Turner April 27, 2015 Hiroshima The attack on Hiroshima was a brutal attack. One of the planes involved in making this bombing a success was named “Necessary Evil”. This plane was one that was used to take pictures of the bombing on the attack and the effects of the explosion. I think that this plane was named “Necessary Evil” because of its “evil” pictures that the plane had captured on the mission of bombing Hiroshima. More people than not believe that the dropping of the atomic bomb on Hiroshima was the right decision to make. Japan had already killed around 2,000 Americans during the attack on Pearl Harbor, and many believe that that was enough to drop a bomb on them. A full scale invasion on Hiroshima would have killed many American lives, so dropping the atomic bomb was a way to kill tons of Japanese and keep more of our guys alive at the same time. Dropping the bomb also ended the war a lot faster than it would have if we wouldn’t have dropped the bomb. Some say that they dropping of the atomic bomb was a little too much. Many believe that we shouldn’t have dropped the bomb on Japan because the atomic bomb was intended to be used as a defense weapon, not an offense weapon. A lot think that we used the bomb just to scare Germany, or any other country for that matter, and maybe they would think twice before attacking the U.S. Some also say that the use of the atomic bomb was racially motivated. It is said that if the bomb would have...

...The Atomic Bomb on Hiroshima and Nagasaki The World War II had been going on for over two years and the U.S. was staying in isolationism. But on December 7, 1941 Japan launched an attack on Pearl Harbor. After this The United States declared war on Japan. On August 6, 1945, little boy, the first atomic bomb ever used in war was dropped on the city of Hiroshima. This resulted in 70,000-80,000 people died immediately and another 70,000 were injured. Hiroshima at the time was very large with roughly 350.000 people living there. It was chosen because it had industrial and military significance. Three days later it was followed by Fatman, the second and last atomic bomb used in war, which was dropped on the city of Nagasaki. This resulted in over 40,000-75,000 immediately dying. Originally Fatman was to be dropped on the city of Kokura, but because of the weather they decided to bomb their secondary target Nagasaki. Nagasaki was important because it was one of the largest seaports in Japan and the large industrial activities including producing military equipment.Many things led up to the bombing of these two great Japanese cities. The first event leading up to the bombing is World War II and Japans involvement in bringing the US out of isolationism. After the bombing of Pearl Harbor the US was already furious with Japan and wanted revenge. Another thing leading up to this event was Manhattan Project. This was started in 1939 when the U.S., feared that the Germans...

...Hiroshima and memory Background During the final stage of World War II 1945, the United States conducted the atomic bombings of the cities of Hiroshima and Nagasaki in Japan. Such events are the only use of nuclear weapons in the world. The atomic bombs were created by the Manhattan Project, which was a research and development program established by the United States with the United Kingdom and Canada that produced the first atomic bomb during World War II. The United States called for a surrender of Japan in the Potsdam Declaration on 26 July 1945 by threatening Japan with “prompt and utter destruction”. However, such ultimatum was ignored by the Japanese government. Thus, two nuclear weapons that developed by the Manhattan Project had been deployed by the United States. Hiroshima was the primary target of the first atomic bomb mission and Nagasaki was the second target of the mission. The first nuclear weapon named Little Boy was dropped from an American B-29 Superfortress, known as Enola Gay on the city of Hiroshima on 6 August 1945 and followed by another nuclear weapon named Fat Man dropped from the B-29 Bockscar on the city of Nagasaki on 9 August. The official figures by Japanese at the time put the death toll at 118,661 and the later estimates the final toll was about 140,000 of Hiroshima’s 350,000 population including military personnel and those who died later due to radiation. On the other hand, the explosion of Fat Man event killed 39,000 and caused a further...

...Truman’s Decision - Was the bombing of Hiroshima justified or not? It was on the afternoon of 6th August 1945 that an event was believed to change and save the world forever. Harry Truman had made a life changing decision to drop an atomic bomb named “Little Boy” in Japan’s Hiroshima. The result of this weapon ended up in destroying more than 4 square miles of the city. The company who made the bomb was called Enola Gay. The motive behind the doing of this was to threaten Japan and make them surrender in World War 2. It is a fact that this was the first time in history that a nuclear weapon was used. This event is still one of the most important topics in history. It has been debated by an abundance of historians: Was it justified despite 129,000 innocent citizens died? There isn’t a definite answer to this but there were both sides to the story. Bombing was justified It is widely believed that the bombing was brutal and cruel. However, it was the reason that ended World War 2, and if America did not drop the bomb, the losses of soldiers would be even at a larger number than the amount of people who died in the drop of the bomb. It has also been said to save a lot of American’s lives and soldiers. This statement is backed up by the quotation “Fighting would be fierce and the losses heavy.” that was said by Harry S. Truman in 1955. This quote can tell us that during that time he believed that if the war was still going on, it was very likely that the upcoming invasions...

...Manhattan Project Research Paper Nuclear research all started when the Japanese bombed Pearl Harbor, and the United States entered into World War II. When the United States realized that Germany attempted to build an atomic bomb, Americans began to concentrate on their research about creating an atomic bomb. President Franklin D. Roosevelt created the Manhattan Project, which included a group of top scientists, under General Leslie R. Groves, who worked around the clock to try to develop an atomic bomb within three years. The Americans and the British combined their efforts to research the development of the bomb and created plants and factories to work in. They created plants for three separate processes: electromagnetic, gaseous diffusion, and thermal diffusion. These plants helped create the plutonium and uranium 235 needed to manufacture the atomic bomb. The secrecy of the Manhattan Project was essential in order to develop the atomic bombs to end World War II. The United States and Great Britain kept the development of the atomic bomb a secret. In order to keep the secret, Groves spread the work out between laboratories so that the people working on the bomb could not figure out they were manufacturing. The members of the Manhattan Project asked the scientists questions about the bomb, and they gave answers back, but they did not know what the responses were for. The project consisted of so many restrictions for the employees in order to keep the secrecy...

But with Allied casualties from an invasion estimated to reach 1 million deaths — plus another 10 million Japanese casualties, including civilians — Allied planners searched for another way to end the war, which they found in the Manhattan Project.

Credit: U.S. National Archives The Manhattan Project Concerned over reports that Nazi Germany was developing a new type of weapon using radioactive uranium, in 1939 U.S. government officials began to investigate the potential of uranium — particularly the uranium-235 isotope — for making a powerful bomb. Within a matter of months, a coalition of American, British and European scientists — many of whom were refugees from Germany, Italy and other fascist nations — began collaborating on a vast international project to develop a uranium-based bomb before any Axis powers beat them to it. Because one early component of the project was based in the U.S. Army's Manhattan District, the name Manhattan Project...

...The Manhattan Project The Manhattan Project was a significant turning point for the United States in World War II. The rumors of the creation of an atomic bomb put the Allies on edge; each wanting to be the first to create such a destructive technology. The reason behind why the US chose to execute this project, the processes and events that took place, and the subsequent effects of the project depict the importance of this major US event. To fully understand the importance of the Manhattan Project, it is first imperative to understand the reasoning behind why the United States chose to pursue the project. In 1939, Allied scientists had fears that Nazi Germany might develop nuclear weapons (The Manhattan Project). At this point in the War, Hitler was at his most powerful. He had one of the largest followings in history and his reign was producing devastating outcomes for the Jewish population (The Manhattan Project). Once the scientific community discovered that German physicists could split a uranium atom, action needed to be taken (The Manhattan Project). Albert Einstein, who fled Nazi Germany to live in the US, felt as though President Roosevelt should be made aware of the dangers of atomic technology being in the hands of Hitler (Ushistory). A letter written by Einstein was received by Roosevelt, yet the President found no reason to immediately respond to such a situation (Ushistory). However, 1941 began the American effort to construct an atomic bomb (The Manhattan...

...Modern History Conflict in the Pacific 1937-1941 Due: Thursday 28th of August, 2008 Alyce Wearne Task: Evaluate the argument that America was justified in using atomic weapons against Japan in 1945. As one of the most significant and consequential decisions in the history of the world, President Harry Truman’s allowance of atomic weapons towards the end of World War II, of which he himself understood would cause both mass devastation and indignation, is still one of the most controversial and heavily debated topics in today’s society. This was partially due to the adverse underestimation and seemingly ignorant approach the American’s had towards their latest development of mass destruction; almost oblivious to the immense aftermath of physical injury, civilian death and emotional torment it would produce for those involved. This decision, ultimately made by one man, affected not only America and Japan, but the world. Dispute over this was, and continues to be highly generated, the event causing anger and infuriation to millions across the world. This resentment did not just accumulate from the lack of awareness and slaughter of innocent life, but from the graphic images shown in newspapers, the casualties, and the torturous amount of death underwent as a result of the bomb. As a Japanese survivor documented: “The appearance of people was . . . well, they all had skin blackened by burns. . . . They had no hair because their hair was burned, and at a glance you...

...History of the A-Bomb In early August 1945 atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki. These two bombs quickly yielded the surrender of Japan and the end of American involvement in World War II. By 1946 the two bombs caused the death of perhaps as many as 240,000 Japanese citizens1. The popular, or traditional, view that dominated the 1950s and 60s – put forth by President Harry Truman and Secretary of War Henry Stimson – was that the dropping of the bomb was a diplomatic maneuver aimed at intimating and gaining the upper hand in relations with Russia. Today, fifty-four years after the two bombings, with the advantage of historical hindsight and the advantage of new evidence, a third view, free of obscuring bias and passion, can be presented. First, the dropping of the bomb was born out of complex infinite military, domestic and diplomatic pressures and concerns. Second, many potentially viable alternatives to dropping the bombs were not explored by Truman and other men in power, as they probably should have been. Lastly, because these alternatives were never explored, we can only conjecture over whether or not Truman’s decision was a morally just one, and if indeed it was necessary to use atomic energy to win the war. The war in Asia had its roots in the early 1930s. Japan had expansionist aims in Eastern Asia and the Western Pacific, especially in Indochina2. In July of 1940 the United States placed an embargo on materials exported to...

...will make in my this rebuttal is that if the dropping of the atomic bomb was a good or bad thing to do after the bombing of Pearl Harbor. My reasons of making this claim is that a whole lot more people died in the atomic bomb, 2,335 soldiers and staff approximately died in Pearl Harbor which is a lot of lives, even one life could mean a lot, but in Japan the number of deaths of 90,000–146,000 people in Hiroshima and 39,000-80,000 in Nagasaki which is nothing compared to Pearl Harbor, this is really a big difference. The biases of my opponent which in this case is U.S. ex-president, Truman who gave the order to drop the Atomic Bomb on Japan, I understand it was for the safety of the country and to show the rest of the world that you don’t mess with the U.S. He did that to try to avoid similar things to...

...Millions of people already dead and thousands more every day. The citizens beg for the conflict to stop but there is no end in sight. A single option seems to be able to end this conflict for good. In World War 2 the United States dropped the Atomic bomb on Japan in order to make them surrender and end the war. The dropping of the atomic bomb was justified in World War 2 because of Japan’s refusal to surrender, it saved U.S. lives and it demonstrated U.S. power. World War 2 was a dark time for all countries involved and especially the United States. Following the war in Europe ending with the death of Adolf Hitler, the war in the Pacific raged on. The United States were fighting with Japan to avenge the bombing of Pearl Harbor which started World War 2. Pearl Harbor was a surprise bombing of a United States naval base by Japan. It killed thousands of people and destroyed large amounts of naval equipment. As the United States fought Germany in Europe, the conflict with Japan was on the backburner. Now with the war in Europe over, Japan is the main enemy. Japan’s military strategy was known to be very unorthodox. With suicide pilots attacking U.S. ships and their relentless mindset made it a daunting task for the U.S. to overcome. In the mainland the U.S. was holding Japanese Americans in internment camps to isolate them from the rest of society in fear they may be giving information to the Japanese. The United States did not see an invasion of Japan as a viable option so they considered...

...Dropping of the Atomic Bomb When it comes down to President Harry Truman dropping the atomic bomb on Japan, it seems everyone has their own personal view or opinion on rather or not he made the right decision. I’m trying to imagine myself in Truman’s time period and the position that he had to take, and I wonder. What would I have done if I was in his shoes? What would I have done differently? Was President Harry Truman’s decision completely unnecessary? Oddly I would have to say I agree with his decision, and I will explain why. First, let me explain to you what led us to the most drastic decision in history. Responding to the drop in Pearl Harbor. “When you have to deal with a beast you have to treat him as a beast (Understanding the drop of atomic bomb, pg. 1). The US had been fighting a long and massive war since 1941. Four years to be exact, is a long time for any fight. Especially when there’s no sign of either of them giving up. This began to put pressure on both leaders from the American casualties and the Japanese attitudes to end the war quickly as possible. Although Germany had finally giving up and surrendered, the Japanese had not. They were going to fight until they couldn’t fight no more, and that’s what they did. The winning of this war was so crucial and meant so much to them. They were willing to kill themselves in explosive air planes in order to kill them. This is how serious this war was to them. Truman later had American air strikes leave millions of...
