Little Boy and Fat Man

The year was 1945, Hitler had died, the remaining German forces have surrendered and Europe had begun to rebuild the damages caused by World War II. However, not all was well, in the Far East the Japanese forces have refused to end their attempts at world domination. No amount of bargaining, threatening, or strategic bombing of military buildings had convinced Emperor Hiroshito to surrender and the Allied forces are scrambling to find any action they may take to avoid an invasion of Japan. This would result in massive casualties on both sides and poses a huge threat on the Japanese civilian’s way of life. The nuclear projects, like the Manhattan Project, were well underway already in an attempt to beat Hitler to …show more content…

Physicist Seth Neddermeyer was credited with making the implosion assembly method (see figure #2). A plutonium-240 core is surrounded with conventional explosives, when detonated; the force from the explosives increases the pressure around the core considerably. This increases the density of the core until the plutonium-240 reaches its critical mass, allowing a fission chain reaction to occur and the bomb to detonate. Because this A-Bomb was using plutonium-240, measures had to be taken to ensure the package would make it to the detonation zone mostly intact. Plutonium-240 has a much higher fission rate than plutonium-239 (the desired isotope) so Neddermeyer’s implosion assembly method was used. (Science Behind the Atom Bomb, …show more content…

Some have seen the usage of two atomic on Japan as a racist act because no atomic bombings were conducted on any European nations. According to Ghosh, a writer for the International Business Times, “About 120,000 Japanese-Americans were rounded up into internment camps during the war, while propaganda (see figure #3) was mass- produced that depicted the Japanese as subhuman and extremely cruel and depraved.” (2011) Plus, the Japanese had bombed Pearl Harbor, the only attack to occur on America during World War II. It wouldn’t be unlikely that the people within the United States had poor ideas about the Japanese and were possibly more accepting of the usage of this unknown

  • Pro: Drop Bomb on Japan

    941 Words  | 2 Pages

    The bombings of 1945 by the United States of America on Japan were very controversial events. Many historians believe these acts were aggressive and unnecessary. In addition, analysts argue that the U.S. should have used alternative methods instead of the bomb, but most do not realize the repercussions of these different tactics. On the contrary, the bomb was needed to ease tension quickly and effectively. Ultimately, the bomb proved more effective than any other method, and also proved to be a technique that is sufficient for America’s needs. The effort made by the U.S. to bomb Japan after their disapproval of the Potsdam Declaration was needed to end conflicts in the Pacific because of Japanese resistance, to save American lives, and to portray the U.S. as a nation of power and dominance.

    In 1939, the scientific world had discovered that Germany was building an atomic bomb. Albert Einstein had fled german prosecution earlier in his life. Upon hearing of Germany’s knowledge of splitting an uranium atom, he felt he must inform President Roosevelt about this. Roosevelt didn’t see the need in the atomic bomb but agreed to it anying. The code name for the atomic bomb was The Manhattan Project. Columbia University, the University of California at Berkeley, and the University of Chicago started the research for the atomic bomb. Enrico Fermi led a group of physicists to create the first controlled nuclear chain reaction underneath Stagg Field. Stagg Field was the University of Chicago’s football field. Here is where the first controlled

With the changes of the nature of power, Japan by balancing out aggressive economic policies and a quiet military buildup, was able to build herself up to become a prominent player in the international sphere today. In closing, while Japan’s policies today in general have been skewered towards the arguments of the ‘Gentleman’, increasingly Japan has considered more realist concerns of security in the escalation of tensions of the East Asian geopolitical sphere. Chomin’s Discourse has nonetheless served as a prophetic blueprint for more than a century of Japan policy-making.

    On February 14, 1942 Lt. General J. L. DeWitt, “commanding general of the Fourth Army and the Western Defense Command[i]” recommended to the War Department, the “evacuation[ii]” of Japanese living along the Pacific coast, deemed a Military Zone. About 120,000 people of Japanese ancestry, many of those people American citizens, living on the West Coast and Southern Arizona were removed from their homes to locations of the government’s choosing. The very term “evacuation” is misleading to say the least because it suggests that the Japanese were being relocated to protect their safety. The excuses cited by the military were to establish “broad civil control, anti-sabotage, and counter-espionage measures.[iii]” The reasons given to justify “evacuation” suggested that the Japanese were a threat to the nation and not the nation a threat to the Japanese.

  • The Atomic Bombing Of Hiroshima And Nagasaki

    “My God, what have we done?” were the words that the co-pilot of Enola Gay wrote in his logbook after helping drop two bombs, one in Hiroshima and one in Nagasaki, that killed an estimated two-hundred thousand individuals. The bombings were completely unnecessary. Japan was already defeated because they lacked the necessary materials to continue a world war. The Japanese were prepared to surrender. There was no military necessity to drop the atomic bombs nor is there any factual information stating that the bombs on Hiroshima and Nagasaki were dropped to “save the lives of one million American soldiers.” The United States bombed Japan in August of 1945. The atomic bombings of Hiroshima and Nagasaki were uncalled for and could have been avoided.

    ...e atomic bomb on Japan was extremely controversial it ultimately ended in America’s favor when Japan surrendered. According to Karl Compton, “it was not one atomic bomb, or two, which brought the surrender; it was the experience of what an atomic bomb will actually do to a community, plus the dread of many more, that was effective.” Hiroshima and Nagasaki will always serve as a reminder of the tremendous effects powerful weapons can have on a country. America consciously decided to seize Japanese lives in order to save American lives. The attack effected Japan in a massive amount of negative ways but the outcome of the atomic bomb did create positive effects for America. The devastation generated by the atomic bomb will never be forgotten by citizens worldwide. “The atomic bomb was more than a weapon of terrible destruction; it was a psychological weapon.” (Stimson)

    The U.S. decided to develop the atomic bomb based on the fear they had for the safety of the nation. In August 1939 nuclear physicists sent manuscripts to Albert Einstein in fear the Germany might use the new knowledge of fission on the uranium nucleus as way to construct weapons. In response, on August 2, 1939, Einstein sent a letter to President Roosevelt concerning the pressing matter to use uranium to create such weapons before Germany (Doc A-1). To support the development of the atomic bomb, President Roosevelt approved the production of the bomb following the receipt that the bomb is feasible on January 19, 1942. From this day to December of 1942, many laboratories and ...

  • Examing the Factors That Led To Dropping the Atomic Bomb on Nagasaki

    1303 Words  | 3 Pages

    To fully examine the factors that led to the United States to drop an atomic bomb on the city of Nagasaki, one can look at the event as a result of two major decisions. The first decision concerned the use of newly developed nuclear weapons in lieu of other military techniques to secure a timely Japanese surrender. The second decision was to use several of these weapons instead of only one. Although the Truman administration displayed little hesitation or ambivalence over the decision to use atomic weapons (Walker, 51), it is important to examine what factors contributed to these swift actions.

    The Manhattan Project was the code name for a science project conducted during World War II by the United States with the partial support of the United Kingdom and Canada. The ultimate goal of the project was the development of the first atomic bomb before Nazi Germany. The scientific research was directed by physicist Julius Robert Oppenheimer while security and military operations were carried out by General Leslie Richard Groves. The project was carried out in many research centers being the most important of them the Manhattan Engineer District located on the site now known as Los Alamos Manhattan Project was the code name for a science project conducted during World National Laboratory. The project brought together a wealth of scientific luminaries as Robert Oppenheimer, Niels Bohr, Enrico Fermi, Ernest Lawrence, etc. . . . Since, after experiments in Germany before the war, it was known that atomic fission was possible and that the Nazis were already working on its own nuclear program, several bright minds met. Many Jewish ex...

    Japan triggered the war that led to the bombing of its two cities with its sneak attack on America’s Pearl Harbor in 1941. Subsequent systematic and flagrant violation of several international agreements and norms through employment of chemical and biological warfare and mistreatment of prisoners of war and civilians aggravated the situation[ Gar Alperovitz, The Decision to Use the Atomic Bomb and the Architecture of an American Myth. (NY: Knopf, 1995), 89]. A response was needed to deal with increased aggression from Japan. Allied military planners had to choose between invading Japan and using the US atomic bombs in 1945[ Ronald Tabaki, Hiroshima: Why America Dropped the Atomic Bomb.

    There are many people who oppose the use of the atomic bombs; though there are some that believe it was a necessity in ending the war. President Truman realized the tragic significance of the atomic bomb and made his decision to use it to shorten the agony of young Americans (“Was the Atomic Bombing”). The president knew of the way the Japanese fought. They fought to the death and they were brutal to prisoners of war. They used woman and children as soldiers to surprise bomb the enemy. They made lethal weapons and were taught to sacr...
