The United States had been in war for almost four years. Over 416,800 American lives were taken, and four percent of the world's population was killed in World War II. America needed a way to end the war as quickly as possible with the fewest U.S. casualties. A Japanese invasion was considered, but it would put American lives at stake. With the invention of the atomic bomb, President Truman made the most debated decision: the decision to use the most deadly weapon ever invented- the nuclear bomb. It was a very controversial decision. On one hand, the nuclear warheads ended World War II as quick as possible. On the other hand, it created mass destruction and devastated the two cities targeted: Hiroshima and Nagasaki. Some say that the United States did not have the right to deploy the two atomic bombs in Japan. The two atomic bombs killed more Japanese than the amount of Americans killed in the bombing of Pearl Harbor. Others think that dropping the nuclear bombs was the right choice. It ended World War II quickly and did not put American lives at stake.
Bombing of Hiroshima and Nagasaki
On December 7, 1941 an incursion occurred on U.S territory. Japan dispatched six of their aircraft carriers, Akagi, Kaga, Soryu, Hiryu, Shokaku, and Zuikaku. The planes flew over a naval base at Pearl Harbor which is in close proximity to Honolulu, Hawaii and attacked the naval base. Over two-thousand three hundred soldiers and sailors were killed and nearly one-thousand were wounded.
When the United States caught word that Germany was close to creating the atomic bomb, J. Robert Oppenheimer and other scientists wanted to create it first, for the U.S. After three years of research, the first small atomic device was exploded on July 16, 1945 in the lab at Los Alamos. Having proved their concept worked, a larger scale bomb was built. Less than a month later, atomic bombs were dropped on Hiroshima and Nagasaki in Japan (Rosenberg).
It was April of 1945 and Harry Truman had been sworn into office following the death of a beloved president, Franklin Roosevelt. President Roosevelt left Truman with the hardest and still most controversial decision of all time, whether or not to drop the atomic bomb on Japan. This decision would determine whether or not the outcome of World War II would be quick or prolonged. The Manhattan project for developing the bomb began with the fear of Germany inventing a type of nuclear weapon. The Allies had just defeated Germany and now, the United States focus was ending war with Japan. America had been in war for four years accumulating 1 million casualties in the process. The United States wanted Japan to surrender unconditionally, as the Germans had done, to the Potsdam Declaration. Japan refused; talk of a land invasion on Japan transpired. A land invasion would result in heavy casualties against on either side. The United States would be facing a different type of enemy as well. The only choice was to drop the atomic bomb on Japan. While some may argue moral and ethical beliefs, they cease to think about who the real victim was and how many lives it saved on either side.
Before the Manhattan Project was even created, President Truman tested to see if the bombs would actually work. Truman funded his testing research from own money to make sure it would be successful. At the end of his three year research, a smaller version of the bomb was created for testing in July of 1945 (Teller 4). The testing booth was 20 thousand feet away from the bomb. The bomb weighed two tons and was put on a seventy foot tall tower made with 220 tons of steel. The experimenters were well dressed and protected, but could still feel the effects of the test bomb. The light was brighter than anything ever seen before and was hotter than the surface of the sun. The bombs explosion created a mushroom like cloud that rose over forty thousand feet high. The bomb completely evaporated the stand made of steel that it was resting on, along with the testing buildings and all that was within its reach.
Effectiveness of the US Foreign Policy (Atomic Bomb)
The United States foreign policy of dropping the atomic bomb on Hiroshima and Nagasaki was found to be fairly effective after all was said and done. The decision of dropping the bomb was a major choice by President Truman. After asking the Japanese repeatedly to surrender the decision was made that they would go forth with the bombs, keeping in mind that Japan had killed nearly 2,000 of the American soldiers in the bombing of Pearl Harbor and many more lives were lost during the Bataan Death March. The government observed that about 250,000 Americans would lose their lives (White Light, Black Rain) in a land attack on Japan, whereas very few would be lost with an air attack; the main goal was to simply end the war without losing many lives.
President Truman's decision to drop the atomic bomb on the cities of Hiroshima and Nagasaki were the direct cause for the end of World War II in the Pacific. The United States felt it was necessary to drop the atomic bombs on these two cities or it would suffer more casualties. Not only could the lives of many soldiers have been taken, but possibly the lives of many innocent Americans. The United States will always try to avoid the loss of American civilians at all costs, even if that means taking lives of another countries innocent civilians.
Atomic Bomb in World War 2
During World War II the United States government launched a $2
billion project. This project, known as the Manhattan Project, was an
effort to produce an atomic bomb. This project was taken on by a group
atomic scientists from all over the world.
The atomic warfare capabilities of the United States were brought about in a letter from Mr. Albert Einstein to Franklin D. Roosevelt, our current president at the time. “It may be possible to set up a nuclear chain reaction in a large mass of uranium, by which vast amounts of power and large quantities of new radium-like elements would be generated…. It is conceivable, though much less certain, that extremely powerful bombs of a new type may thus be constructed.” His letter was the inspiration for the atomic bomb. Although it took a while for Roosevelt to realize what we had stumbled upon, his close friend Alexander Sachs helped him realize the possibilities. Two years later in November Roosevelt appointed a committee to advise him on nuclear fission and the capabilities of the concept in war. At the head of this committee was Secretary of War Henry L. Stimson. About a month later, an event happened that would change the history books forever. The Japanese bombed Pearl Harbor, Hawaii at about 7:50 in the mourning. This brought America into the war and the Manhattan Project was on its way. The Manhattan Project included the designing and construction of the atomic bomb, and the execution of dropping the bomb on Hiroshima and Nagasaki. There were three major research and production sites for the project. The first was Los Alamos, near Alamogordo, New Mexico. This is where the actual weapon would be designed. The head of this site was Julius Robert Oppenheimer; this caused a small uproar because of past involvement in pro communist’s activities. The second site for the Manhattan Project was in Oak Ridge, Tennessee. At this site, scientist and laborers were separating U-235 from U-238. Here the Hiroshima bomb was built in huge buildings and the locals could only imagine...
The idea for a Nuclear Bomb came into the picture, during World War II. The code name for the project to create it was the Manhattan Project. It was named for the Manhattan Engineer District of the US Army Corps of Engineers, because much of the early research was done in New York City. In 1942 General Leslie Groves was chosen to lead the project, and he immediately purchased a site at Oak Ridge, Tennessee for facilities to separate the necessary ur...
