Manhattan Project Effects

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

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

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").

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.

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

On August 15th Japan surrendered, and on September 2nd, 1945 they signed the “Instrument of Surrender”. Hospitals were filled with patients who had not seemed sick before. People vomited, bled from their gums, and spots had begun to appear on their skin. Later Japanese doctors discovered that the people were dying from radiation that came from the atomic bomb. {look up: conspiracy theory} When considering using the atomic bombs, President Truman took into account the lowest possible cost for ending the war, he also wanted to end the war quickly. Truman once stated, “When you have to deal with a beast you have to treat him as a beast.” After the Pearl Harbor invasion. The U.S. started with “Operation Downfall,” invading Kyushu, many casualties where estimated, but this war proved to be even more deadly than predicted. General MacArthur thought that dropping more bombs, and using air power by itself would protect American lives, while also bringing forth a quicker surrender from the Japanese. When I look at both sides of the 1945 Japan bombing I really tried to stay open about the different viewpoints. The fact that the U.S., Britain, and the Netherlands crippled Japan was interesting to find. I felt that the Japanese did not want to compromise, and in some way bit the hands that fed them. It seems these allies had allot of power. The Japanese seemed to only

“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

Japan and the United States had different kinds of relations that could have lead Japan to bomb Pearl Harbor.The United States military and Japan’s relationship seemed to get worse after Japan sank the USS Panay even though Japan apologized for sinking the ship. Japan became aware of the 19th and 20th century that there was threats from the different nations influence became very loyal. During 1939 - 1945 the United States, for the second time, applied domestic penalties to Japan and sends to Europe military supplies because Germany, Italy, and Japan made the Anti Comintern Pact. Japan wanted to take control over some land in northeastern China, this lead to domestic penalties that were charged against Japan from the United States and Europe. Even though the United States saw Japan as a minor threat because Japan had a few military compared to the United States navy. Japan decided to

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.

During the war, the United States started developing a weapon that would prove to be devastating to its enemies. The creation of the atomic bomb was made when a group of scientists discovered that splitting uranium atoms could cause massive destruction. President Harry Truman, who succeeded Roosevelt made the executive decision to use this atomic weapon against Japan in hopes of bringing the war to an end sooner. On August 6th, 1945, the atomic bomb was loaded on the Enola Gay. The plane left the Mariana Islands in search of Hiroshima about six hours away to drop the first atomic bomb. The bomb devastated the city, killing between 90,000 and 146,000 people. Three days later, a second

Japan had no allies going into this war.Japan had the upperhand in the air and sea in the beginning of WW2. They had this domination for 4 years and had a turning point around March 1945, after a long time of naval,air, and land battles. They had an upper hand because they use the element of surprise

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.

Prior to World War Two Japan had been going through an economic crisis and was having issues with its government. The Japanese society was very militaristic and prideful making it a key power in world affairs. Their people have a strong and deep seated loyalty to their country.

This committee decided that the United States should retain nuclear superiority, in the event that international relations deteriorated following World War II (US Department of Energy). This decision is a foreshadowing of the Cold War, and nuclear arms race which followed the dropping of nuclear weapons on Japan. The interim committee also decreed that a regulatory system should be created to control the development of nuclear weapons, since other nations would inevitably obtain the technology needed to develop weapons. Possibly, the most influential decision made by the interim committee was to keep the details of the atomic bomb a secret, to maintain the shock effect, until after it had been dropped on Japan. Two atomic bombs were dropped on the Japanese cities of Hiroshima and Nagasaki. The first bomb dropped was a uranium bomb, nick-named Little Boy, was untested before its detonation (US Department of Energy). The second, dropped after the Japanese did not surrender, was a plutonium bomb, nick-named Fat Man. The dropping of these bombs propelled the United States to a seat of world power, as they were the only country to obtain a weapon of mass destruction. The Manhattan Project became scientific and engineering feat, employing over 100,000 individuals. The exceptional organizational model the Manhattan Project provided, allowed for great scientific achievements in the later part of

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
