In 1939, German scientists reached a milestone when they learned how to split a uranium atom. Soon fear would spread over the world that the Nazis would use this power to gain an advantage in the war. Scientists Albert Einstein and Enrico Fermi would escape from persecution in Europe to live in the United States. Einstein would send a letter to the president urging him to develop an atomic research program (“The Manhattan Project”). Roosevelt would approve the program and work would soon begin on developing the the atomic bomb. When work on developing the bomb was complete, President Truman faced an important decision: to drop the bomb on Japan to end the war or not.
When Einstein sent the letter to Roosevelt, Roosevelt saw neither the necessity or the utility for the program. However he would agree to proceed slowly with the program. The development of the atomic bomb received its codename: the Manhattan Project. In the beginning of the project, research was based at only a few universities: Columbia University, the University of Chicago, and the University of California at Berkeley. Physicists reached a breakthrough when they gained the ability to produce the first controlled nuclear chain reaction under the grandstands of Stagg Field at the University of Chicago.
After this breakthrough, the project was able to advance tremendously. This allowed funds for the project to be allocated more freely. Nuclear facilities were built at Oakford, Tennessee and Hanford, Washington. The main assembly plant was located at Los Alamos, New Mexico. There Robert Oppenheimer was put in charge of the plant. Research and development of the bomb totaled nearly 2 million. Over 120,000 Americans were employed for the Manhattan Project.

Truman received criticism from his decision to drop the bomb (Morton). Many critics argue that Truman’s decision was a barbaric action and brought the United Stated negative long-term consequences ("The Decision to Drop the Bomb"). Morton states that Truman’s decision was influenced by his senior and trusted advisors. However the decision to drop the bomb was his alone in the end.
In conclusion, Truman’s decision to drop the atomic bomb did bring an end to the war with Japan. Although critics claim that dropping the bomb was a barbaric action, it ended the war sooner thus saving thousands of lives. Critics explain that Japan was weak and on the verge of surrender, and dropping the bombs were unnecessary. To this day the United States remains the only country to use a nuclear weapon against another country.
Decisions are the hardest thing to make, especially considering how Harry Truman decided to drop the US Atomic bombs onto Okinawa and Iwo Jima. The role of ending the war with Japan was in his hands, but it would require releasing the most horrendous weapon ever known. However, there was some controversy over Truman’s decision. Some people say that it was unnecessary to use the Atomic bombs, such as the Federal Council of Churches and the Christian Faith. They stated that: “As American Christians, we are deeply penitent for the irresponsible use already made of the atomic bomb.
The purpose of developing this weapon was first and foremost winning the war as quickly as possible. In addition to securing world peace, the United States’ future as a world leader was also at stake. In 1939, President Franklin Roosevelt appointed a committee to research the possibility of using atomic energy military purposes. By the time the United States entered the war in December 1941, this research was given priority and the project was extended throughout the course of the war. Due to the extremely sensitive nature of the Manhattan Project, only a select few knew of the plan to develop the atomic bomb.
There are many opinions surrounding the question: Was the decision by Truman to drop the atomic bomb ultimately the right or wrong decision? Not only can this question be answered in many different ways, it can be interpreted in many different ways as well. Overall, Truman ultimately made the right decision to drop the atomic bomb. This can be supported by the fact that the atomic bomb helped prevent the deaths of American troops, saved the lives of foreign citizens, and in comparison the atomic bomb was not as destructive as the firebombing in Tokyo.
In 1941, The United States began an atomic bomb program called the “Manhattan Project.” The main objective of the “Manhattan Project” was to research and build an atomic bomb before Germany could create and use one against the allied forces during World War II. German scientists had started a similar research program four years before the United States began so the scientists of the “Manhattan Project” felt a sense of urgency throughout their work (Wood “Men … Project”).
One of the most controversial decisions that have been made, in the history of the United States, was Harry Truman’s decision to drop atomic bombs on the two Japanese cities of Hiroshima and Nagasaki. The ever so controversial topic of the dropping of the atomic bombs has successfully driven people insane. People feel strongly that this decision was atrocious and unnecessary, while others believe the polar opposite, that it was completely necessary. Some historians argue that the human cost to the Japanese population can never justify the use of such weapons. Other historians see it from an optimistic perspective, that it would not have been moral if atomic weapons had not been used to end the war as quickly as possible. President Harry S.
The Manhattan Project The Manhattan Project was a research project, that created the United States first nuclear weapon, and led to its creation of the nuclear department during World War II. M.A.U.D. / M.A.U.D. group was created in 1940. Also, M.A.U.D was the secret name given to the group and it came from a phrase in a message from Niel Bohr (Cohen). This group produced a report that said that producing a fission bomb was possible. James Chadwick, a new member of the British M.A.U.D group, later wrote that at that time he realized that a nuclear bomb was able to be built in his lifetime.
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.
The dropping of atomic bombs on Hiroshima and Nagasaki, Japan were ethical decisions made by President Harry Truman and the United States government. By the time of the atom bomb was ready, the U.S. had been engaged in military conflict for over four years and lost over 400,000 soldiers. Truman claimed, "We would have the opportunity to bring the world into a pattern in which the peace of the world and our civilization can be saved" (Winkler 18). The bomb was aimed at ending the war immediately and avoiding prolonged battle in the Pacific Theater and the inevitable invasion of Japan. President Truman hoped that by showing the Japanese the devastating weapon the U.S. possessed, that the war could be brought ...
In 1945, Germany had surrendered, but the war in the Pacific raged on. The allies were becoming desperate to end the war before it was necessary to carry out a full scale invasion. New developments in science had made it possible for the United States to weaponize the atom, and the consequent bomb created was dropped on Hiroshima and later Nagasaki at the approval of President Harry S. Truman and his advisors. In years to come, Truman would have to face questions over the merit of his actions. Although some may believe the atomic bomb was needed because it ended WWII, it was unnecessary to drop the nuclear bomb because of the alternatives that existed, the effect it had on the Japanese people, and because of the unethical reasons for dropping it.
“Early in 1939, The worlds scientific community discovered that German physicists had learned the secrets of splitting the uranium atom and word spread quickly and several countries began to duplicate the experiment.” Albert Einstein warned President Roosevelt that Germany may have already built an atomic bomb. Roosevelt did not see an urgency for such a project, but agreed to proceed slowly. In 1941, British scientists pushed America to develop an atomic weapon. America’s effort was slow until 1942 when Colonel Leslie Groves took over. He quickly chose personnel, production sites and set schedules to invent the atomic
The decision to drop the atomic bomb was contemplated by officials in the American government for a prolonged period of time. Ultimately the conclusion was that dropping the bombs would be beneficial to America. The American government rationalized dropping the bombs by stating that it would terminate the war with Japan and save a plethora of American lives. America did issue an ultimatum declaring that Japan should cease to resist and in return conditions would be provided for Japan to finish the war with honor. This ultimatum was ignored and the alternative was absolute destruction of Hiroshima and Nagasaki. (Dollinger) Most officials believed that taking this last step would force Japan’s surrender and shorten the war which would result in a decrease of American casualties. (Barnes) Winston Churchill approximated that one million American lives were preserved by utilizing the atomic bomb.
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 ...
The United States’ decision to drop an atomic bomb on Hiroshima required extensive research leading to its production. The main goal of the American side was to damage the enemy’s confidence, while choosing a target with the highest military output in order to conclude the war (Robinson).The group in charge of developing the technology was known as the Manhattan Project, and was kept top-secret. Selection began in the spring of 1945, with assistance from the Commanding General, Army Air Forces, his Headquarters (Robinson).There was a variety of experts working on the project, including mathematicians, theoretical physicists, and specialists trained in weather and blast effects Headquarters (Robinson). In order to monitor all of the results, the city had to be untouched, meaning the target had to have no signs of previous bombings. Based on these requirements, the designation of Hiroshima for the bombing was not a simple determination. After a target was selected and the weapon was developed, testing was set to begin. On July 16, 1945, the first test in Alamogordo, New Mexico, proved that the bomb was prepared for release onto...
While Truman had his reasons for using the bomb, there were people who agreed with him were the orthodox historians while the people who disagreed called revisionists. Truman had thought through the possibilities and had decided that using the bomb would be the most effective and quickest tactic. As a president, Truman had a responsibility to protect his country, citizens, and foreign affairs, so deciding on the best method to establish everybody’s needs was difficult. There were many things to worry about: fighting in Iwo Jima and Okinawa, bombing Japan, and building the bomb. His decision was mainly based on how the US citizens felt and the actions of Japan.
At 5:30 AM July 16th 1945, the nuclear age had started. The world’s first atomic bomb was detonated. On August 6th 1942 at 8:15 AM, an American B-29 bomber, the Enola Gay, dropped a perfected atomic bomb created by the Americans, over the city of Hiroshima hoping to end the war. Thousands of people died in the two cities in Japan. They were Hiroshima and Nagasaki “the Manhattan Project”. The research and development project that produced these atomic bombs during this time was known as “the Manhattan Project”.
