The Manhattan Project: the End of World War II or the Beginning of the Nuclear Weapons Age? In August of 1945, the United States military was beaten, battered, and ready to end World War II. The Germans had surrendered, silencing the European theatre, but the Japanese threat remained in the Pacific. The American forces knew that an invasion of Japan would cost nearly half a million lives, an amount which President Truman felt could not be sacrificed. In an effort to end the war quickly, with minimum American lives lost, the United States dropped two atomic bombs on Hiroshima and Nagasaki, Japan. Now, seventy two years later, it is easy to look at the ramifications of the atomic bomb and call America’s actions unwise and catastrophic. However, the leaders of the American military saw the bomb as the only option to end World War II. The dropping of the atomic bomb effectively ended World War II, but its consequences not only drastically affected the people of Japan, but also determined the future of military weapons technology. To understand why President Truman decided to drop the bomb, one must first understand the political and military climate of August 1945, as well as the entire war. On December 7th, 1941, Japanese forces attacked the American naval base Pearl Harbor. On December 8th, President Roosevelt delivered the “day of infamy” speech to congress, and congress declared war. Four years and 416,800 American deaths later, Japan still posed a formidable threat to
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.
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.
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.
The Manhattan Project was one of the most notorious and catastrophic projects in United State history. A bomb that took years to perfect and made the U.S. gamble millions of dollars on new technology that wasn't certain to work. All the secretive facilities scattered all over the U.S. contributed to the creation of a futuristic weapon of mass destruction beyond anyone’s imagination. The atomic bomb caused thousands to die and left years of remnant radiations. The Manhattan Project will forever remain as one of the greatest “successful” catastrophic discoveries in human history.
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
Japan had a very strong entry into World War II. After destroying the United States with the Pearl Harbor Attack on December 7th, 1941, they were in a great place. Over the next couple of years in war, The United States joined with Great Britain, and other countries, and formed The Allies. After Germany had conquered most of Europe, the Allies slowly but shirley took over, and freed the countries Germany had invaded. On May 7th, 1945, Germany had surrendered, and Japan was the last enemy fighting in the war against The Allies (Stein). For the short period of time, Japan was struggling. With the United States plotting the atomic bomb, Germany joining with The Allies against them, and the Soviets considering to fight in the Pacific, Japan was
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.
In the year 1945 the global theater saw the Second World War come to an end. Germany surrendered in May, and the Allies began to focus on laying siege to Japan. By June the Untied States army forced them back to their native island, yet the Japanese kept fighting despite their hopeless situation. On August 6 an American atom bomb codenamed “Little Boy” was dropped on Hiroshima, and three days later “Fat Man” was dropped on Nagasaki. The official purpose of these bombs was to minimize casualties, yet there is more to the Manhattan Project that implies other motives.
Leading up to this time the fascist dictators began to gain power in European countries. The big three being the countries of Nazi Germany, Adolf Hitler, Italy, Benito Mussolini, and Japan, Emperor Hirohito. In 1935 Italy invades and conquers Ethiopia, shorty after Nazi Germany and Fascist Italy sign a treaty of cooperation. In 1937,Japan, lead by Hirohito, invaded China. Joseph Stalin, of Russia, signs the German-Russian non-aggression pact; which allowed Hitler to invade Poland. But when news of the German invasion of Poland spread Britain along with France joined the war to oppose the Germans. Germany only continues in it’s quest for conquest by invading Denmark and Norway in the year 1940. Meanwhile the United States is remaining completely uninvolved under it’s Neutrality Act that was passed in 1935. The United States, lead by president Franklin D. Roosevelt, enacted it’s Lend Lease Act in 1941 in order to trade and sell to allied forces, for payment after war. Japan realizes that the U.S. wasn’t exactly being neutral so it sent suicide bombers to attack our naval base in Pearl Harbor on December 7, 1941. Thus leading into the use of the atomic bomb, but first the construction, an event referred to as the Manhattan Project. The name Manhattan Project came about because the program began under the Manhattan Engineering District of the War Department.
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 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
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
“I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones.” -Albert Einstein was the most famous physicist in the world. Albert Einstein was one of the many members of the Manhattan Project and was also intel to the President. He was actually one of the many causes for the project after sending president Roosevelt a letter telling of NAZI germany’s plans. Okay so most people know what came out of this project and it’s success. Right? But what about the dangers that came with it and it’s product? My paper will prove that the Manhattan Project was the most deadliest project of the 20th.
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.
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
