Manhattan Project Effects

Japan was affected the most by the Manhattan Project with the killing of many Japanese. Some people agree, but some people disagree and state that the United States was affected the most. Who was affected the most?

To ensure his plan, the Manhattan Project was created to develop an atomic bomb that would have a chained reaction in order to get a massive explosion. However, the goal was to create this nuclear technology before German scientists could figure it out. To test the atomic bomb and to see if it would be successful on Japan, they created the Trinity Test 210 miles south of Los Alamos (which was the headquarters of the Manhattan Project) which tested a plutonium implosion device. The results were successful and when they dropped the bomb from the tower, it created a crater and shattered windows 125 miles away! Furthermore, as President, it means Truman is appointed Commander in Chief, meaning he runs the armed forces. President Truman is justified to his decision of dropping the atomic bomb because it’s his duty as President to make those calls. Equally important, in Document A, President Truman states, “...[The atomic bomb] would be likely to bring the war to an end.” In the best interest of the Americans, Truman knew dropping a 5-ton bomb would quickly end the war against Japan, therefore making the Americans feel secure and

The Manhattan Project had various short and long term affects around the world. Primarily, the research done to create an atomic bomb led to the discovery of how to harness nuclear power which affects our lives to this day. However, the Manhattan Project also led to the creation of two more atomic bombs which would be used in WWII, radiation poisoning resulting in the death of many , fear of nuclear weapons during the Cold War, the end of the Second World War which was still taking place in Japan, and the threat of nuclear weapons around the world that still exists.

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.

The creation of the atomic bomb came about after Albert Einstein warned President Franklin Roosevelt about the Germans experimenting with nuclear technology and recommended its military potential for the US. The Manhattan project was then commission to research and build atomic weapons. After the surrender of Germany and Italy as well as the death of President Roosevelt, Harry Truman was thrown into the driver’s seat and had to deal with last fighting Axis Power, Japan. Truman assembled multiple committees of high ranking military officials in order to decide whether to use the atomic bomb to force Japan’s surrender. The committee members came to a unanimous decision that the atomic

Imagine yourself making the toughest decision in your life, whether sacrificing a million of our men and thousands of war ships and plans, verses several thousand of Japanese civilian populists. This decision was on the shoulder of Harry S. Truman, the United States President, who had to make this decision by deciding whether or not to drop a newly designed weapon. The atomic bomb was tested in the sands of New Mexico, where it proved to be very successful. Harry S. Truman made a very successful decision, because he wanted to end the war quickly, show others that the United States had power, and the retribution of Pearl Harbor.

“We believe that . . . an early unannounced attack against Japan inadvisable. If the United States were to be the first to release this new means of indiscriminate destruction upon mankind, she would sacrifice public support throughout the world, precipitate the race for armaments, and prejudice the possibility of reaching an international agreement on the future control of such weapons. Much more favorable conditions could be created if nuclear bombs were first revealed to the world by a demonstration in an appropriately selected uninhabited area.” The initial test for the atomic bomb was dropped in Alamogordo, Mexico with experts observing more than 20 miles away. The explosion was estimated to be a blast of about 10,000 tons of TNT. The Atomic bomb’s intense and destructive power frightened many scientists who were working on the Manhattan Project (Knebel 78). Including the father of the atomic bomb, J. Robert Oppenheimer. Oppenheimer felt as if he had created something that would bring forth destruction to the world, instead of using his brilliant scientific mind to improve and usher the world into an era of peace like he intended to. In fact, many scientists within the Manhattan Project were shocked and against using such a powerful weapon as the atomic bomb against other humans, so much that a group of scientists and

It became known that the German knew how to create an atomic bomb and FDR created a committee to study and create atomic bombs, named the Manhattan Project.The Manhattan Project was significant to the war because it led to the end of World War II and caused the Japanese to surrender to the Americans. The amount of people working together along with the cost and time which led to advancements in technology that was far ahead of any enemy. The creation of the bombs delivered a push in the advancement of science, innovation, designing, military and the entire of society into another age. It drew out the powerhouse that we consider today to be the United States of

The first atomic bomb that Japan was to get a glimpse of was on August 6th, 1945, during World War II in the city of Hiroshima. The explosion annihilated 90 percent of the city; without hesitation killed 80,000 people. More than tens of thousands of people would have eventually died due to radiation exposure. Within three days of the attack, a second B-29 dropped another A-bomb in another location known as Nagasaki, killing an estimation of 40,000 people. Hirohito, Japan’s emperor announced his country’s unequivocal surrender in WWII in a radio address on August 15th, in allude to the calamitous power of “a new and most cruel bomb.” President Truman had to make one of hardest pre arrangements that he had ever faced. Truman based this decision off of the results of to justify the cost of the Manhattan project, in response of

Truman agreed and stated that if the weapon was achievable it will certainly have a clobber on those Russians. The war with Japan dragged on and it appeared too much as if the Japanese should never surrender. On July 16, the team of scientists at the Alamogordo, New Mexico, research station denoted the first atomic bomb. Truman gave Stimson the handwritten order to release it, when ready, but not sooner than August 2 on July 31, 1945 ("Truman is briefed on Manhattan Project").

September 1, 1939, marked the beginning of World War II. The war was long fought involving the three axis powers and several allied powers. Among those were Japan and the United States following Japan’s surprise attack on Pearl Harbor in 1941 (Praino, 2015). Hundreds of thousands of lives were lost amongst the battles from each side of the war. In 1939, Albert Einstein and Enrico Fermi fled to America and informed the elected officials that Germany had discovered new outbreaks in splitting atoms, which was one step closer to the creation of destructive weapons for the Axis power. With that news, American facilities launched a program that would later be codenamed “The Manhattan Project” which was the birthplace of the first nuclear atomic reactions. After the first reaction was created, it was a vicious cycle from there that continued to escalate. With the war reaching an all-time high in casualties, Truman was faced with a big decision as the programs had finally experienced breakthroughs to the atomic bomb. He could choose to remain in conventional war tactics and continue to prolong the war until Japan was ready to surrender, or attempt to save the lives of many American soldiers and citizens by dropping the atomic bombs onto two major cities in Japan (Praino, 2015). By choosing the latter, an estimated 225,000 Japanese lives were lost (Perkins, 2016) and the ethical merits of Truman’s decision are still questioned today while some views remain confident in the choice.

In the conclusion of World War II, Harry Truman was forced to make a tough decision about using atomic weapons. President Truman had four options: first, to continue predictable bombing of Japanese cities; second, invade Japan; third, reveal the bomb to an unpopulated island; or last, drop the bomb on a populated Japanese city. Truman chose to drop the atomic bomb on a populated area of Japan, Hiroshima. The first atomic bomb was dropped on August 6th of 1945.

Roosevelt's secretary of agriculture, Henry Wallace, Jimmy Byrnes and Truman met at Washington’s union station for a meeting. Truman heavily relied on Byrnes for advice and Byrnes was also the first to tell Truman about the atomic bomb. By the end of 1944, the Japanese airforce was extremely weak, it was clear that they were going to try to finish the war soon. The Japanese asked for peace and the US understood that the Japanese wanted the war to be over soon. Truman’s advisors wanted the war to end sooner and put pressure on Truman. The US was also offered a deal from the USSR on ending the war, the US refused because they felt they could do better. The US continued at war with Japan. Curtis LeMay, a major in the US army sent 330 planes over with flammable bombs to hit Tokyo because the city is built up with wood and bamboo. This event killed up to 100,000 civilians. On May 8th, 1945 the war in Europe, the war and Asia continued. Even though the Germans surrendered the US was still planning on continuing the war in Japan. In July 1945, Truman attended the conference of Potsdam in order to ensure the Soviets entry into the Pacific war. Truman delayed this conference by two weeks in order to give the scientist more time for testing the bomb in New Mexico. Truman deceived that the US had a new unusual destructive force on July 24th, though Stalin did not understand the extent of how dangerous this bomb was. Truman was in charge of The Manhattan Project, this was the decision of whether to drop the first atomic bomb ever to be used at war or not. Truman, George Marshall and Dean Acheson were known as a group called ‘the wise men’. This group was called upon to give Truman advice for his

Between 1944 and 1945, the Allies attacked Germany and the U.S. advanced across the Pacific to the doorsteps of Japan. In these last two years of war, Americans also created a new form of weapon that changed both warfare and global politics. With advances in technology, the Allied and Axis scientists were able to construct the most deadly, crucial weapon, the atomic bomb. Its creation started in 1942, when President Roosevelt presented the Manhattan Project as a priority in the development of the atomic bomb. However, the decision to use this mortal weapon fell into the hands of the new president, Harry Truman. He had to decide whether to save the lives of millions of Americans or to kill thousands of innocent Japanese families.

With the approval of American President Harry S. Truman, the fates of two Japanese cities, Hiroshima and Nagasaki were sealed. This decision came with heavy hearts, as the United States attempted to end their involvement in World War II by using nuclear power against the nation of Japan. Truman’s primary goal in this form of attack was to discontinue the war as quickly as possible, while also sending a message to the enemy and establish the United States as the leader in atomic energy. Beginning as a secret operation labeled the Manhattan Project, atomic bombs became the new weapons of mass destruction. The evident frontrunner in nuclear technology, the United States was the first country to release atomic bombs on another nation for war
