Race for Nuclear Arms and Power
Harry Truman (1884-1972) was the most influential person in the race for the super bomb. As President Roosevelt’s Vice President, he knew nothing about the development of the atomic bomb. But within months of assuming the office of President of the United States on April 12, 1945, he became the first and only American leader to authorize the use of atomic weapons against an enemy target. Truman’s era only marked the beginning of the race for nuclear weapons. The development of nuclear weapons is still an issue today, decades after Truman left office.
Enrico Fermi (1901-1954) succeeded in splitting the uranium atom and the Nobel Committee later awarded him the 1938 prize for physics. At Columbia University in New York, Fermi realized that if neutrons are emitted in the fissioning of uranium then the emitted neutrons might proceed to split other uranium atoms, setting in motion a chain reaction that would release enormous amounts of energy.(1) Fermi had succeeded in taking one of the first steps to making an atomic bomb.
A decade later on July 16, 1945, the U.S. detonated the first Atomic Bomb near Alamogordo, New Mexico. It was called the "Trinity" test and exploded with a force equivalent to 18,000 tons of TNT.(2) Truman then made the controversial decision to drop the bomb over Hiroshima on August 6, 1945. The "Little Boy" Atomic Bomb exploded 1,900 feet above Hiroshima with a force equivalent to 12,500 tons of TNT.(3) Bomb related deaths totaled over 140,000. Then three days later on August 9, 1945, the "Fat Man" Atomic Bomb exploded 1,650 feet over Nagasaki with a yield equivalent to 22,000 tons of TNT.(4) A little over 70,000 died in Nagasaki by the end of 1945 from the effects of the b...

The Revisionists and the orthodox views are different opinions on President Truman’s decision to use the atomic bomb. The revisionists believed that Truman’s decision was wrong and there could have been alternatives. They say that the Bomb was unnecessary and it was only used as a “diplomatic tool” and to show the power of th...
Physicists found out that among the pieces of a split atom were newly produced neutrons. These might encounter other uranium nuclei, cause them to split, and start a chain reaction. If the chain reaction was limited to a moderate pace, a new source of energy could be the result. The chain reaction could release energy rapidly and with explosive force. Leo Szilard, Eugene Wigner, and Edward Teller, Hungarian-born physicists, were frightened by the possibility that Germany might produce an atomic bomb.

Truman, Harry S. "Statement by the President of the United States." SIRS Decades. ProQuest, 25 Apr. 2005. Web. 14 Feb. 2014. . This source is a statement given by President Truman to the people of the United States. In the statement he discusses the use of atomic energy in order to ensure US safety in the war. This source is valid because it is a primary source from a trusted research database, SIRS Decades. The article's bias is evident because it is pro-US and does not show alternative viewpoints. I will use this document to show how the use of atomic energy brought the US into the forefront of global politics and made the US a superpower.
Atomic Bomb The use of the atomic bombs on Japan was necessary for the revenge of the Americans. These bombs took years to make due to a problematic equation. The impact of the bombs killed hundreds of thousands of people and the radiation is still killing people today. People today still wonder why the bombs were dropped. If these bombs weren’t dropped on the Japanese the history of the world would have been changed forever. The Atomic bomb took 6 years to develop (1939-1945) for scientists to work on a equation to make the U-235 into a bomb. The most complicated process in this was trying to produce enough uranium to sustain a chain reaction. The bombs used on the cities cost about $2 billion to develop, this also making the U.S. wanting to use them against Japan. “Hiroshima was a major military target and we have spent 2 billion dollars on the greatest scientific gamble in history- and won.” (3) The bomb dropped on Hiroshima weighted 4.5 tons and the bomb used on Nagasaki weighted 10 kilotons. On July 16, 1945, the first ever atomic bomb was tested in the Jamez Mountains in Northern New Mexico, code named “Gadget.” The single weapon ultimately dropped on Hiroshima, nicknamed “Little Boy,” produced the amount of approximately twenty- thousand tons of TNT, which is roughly seven times greater than all of the bombs dropped by all the allies on all of Germany in 1942. The first Japanese City bomb was Hiroshima on August 6, 1945. An American B-29 bomber, named Enola Gay, flown by the pilot Paul W. Tibbets, dropped the “Little Boy” uranium atomic bomb. Three days later a second bomb named ”Fat Boy,” made of plutonium was dropped on the Japanese city of Nagasaki. After being released, it took approximately one minute for Little Boy to reach the point of explosion, which was about 2,000 feet. The impact of the bombs on the cities and people was massive. Black rain containing large amounts of nuclear fallout fell as much as 30km from the original blast site. A mushroom cloud rose to twenty thousand feet in the air, and sixty percent of the city was destroyed. The shock wave and its reverse effect reached speeds close to those of the speed of sound. The wind generated by the bombs destroyed most of the houses and buildings within a 1.
A huge proponent to the use of the atomic bomb on Hiroshima and Nagasaki on August 6 and August 9 of 1945 was President Harry Truman. Although they value the ideas and contributions out in by the committee they choose, the president ultimately has the last say on war time decisions. It just so happens that President Truman wanted to drop the bomb. President Truman believed that Japan's leaders would not surrender to the terms outlined in Potsdam meeting. He saw it fit to drop the bombs and end all doubt.
After Truman decided to bomb Japan, they had to plan it out. They first had to decide where to release the bomb. They ended up choosing Hiroshima, Japan and Nagasaki, Japan as their two locations. Hiroshima was a significant military city in the war. It confined two army headquarters and was Japan’s communication center (World War 2 Atomic Bomb 1). Hiroshima was also a huge industrial city and had not been bombed before so it would let Japan see the wrath of the United States (Koeller 1). The planning and actual event of the bombing went great. On August 6, 1945 at 8:15 in the morning the bomb was dropped. The bomb that landed in Hiroshima was called the “Little Boy” (World War 2 Atomic Bomb 2). The bomb ended up killing about 170,000 people. 70,000 people died the first day and 100,000 people died in the next few months due to the radioactivity of the bomb and burns fro...
“Little Boy” and “Fat Man”, the world’s first two nuclear bombs were dropped in two major cities in Japan: Hiroshima and Nagasaki on the 6th and 9th of August 1945. This “experiment” by the United States Government completely demolished the two cities, killing over 150,000 people instantly and nearly 50,000 people died from aftermath as well as radiation.
When President Truman authorized the use of two nuclear weapons in 1945 against the Japanese in the cities of Hiroshima and Nagasaki to end World War II, the nature of international security was changed irreversibly. At that time, the United States had what was said to have a monopoly of atomic bombs. Soon thereafter, the Soviet Union began working on atomic weaponry. In 1949, it had already detonated it first atomic bomb and tensions began to heat up between the two countries. With the information that the Soviets had tested their first bomb, the United States began work on more powerful weapons1, and a fight for nuclear superiority had begun.

At approximately 8:15 on Aug 6th 1945 a US B-29 bomber dropped an atomic bomb on the Japanese city of Hiroshima. Instantly killing around 80,000 people, 3 days later, a second bomb was dropped on Nagasaki, causing the deaths of roughly 40-80,000 more people. In the months following the attack, roughly 100,000 more people died slow, horrendous deaths as a result of radiation poisoning. In less than 100 hours two cities were completely destroyed and somewhere between 250-300,000 people were killed. The dropping of the bombs, which occurred by executive order of the US president Truman, remains the only nuclear attack in the history of the world…
In 1940, the Manhattan Project was started, a top secret organization that produced materials for atomic bombs. Franklin Roosevelt had this project prepared in case of the need to use such destructive weapons in WWII. On July 16, 1945, the Manhattan Project had its first successful test. At the Trinity Test Site in Alamo, New Mexico, they conducted the first detonation of a Plutonium bomb. As it turned out, the Manhattan Project's bombs were need to end the war. Harry Truman, who had only been told about the Manhattan Project a few months before because of Franklin Roosevelt's death, dropped the first of two atomic bombs on Hiroshima, Japan, on August 6, 1945. Hiroshima was and still is a transportation center and one of Japan's largest cities. After the Eagle, Gray dropped the Uranium fueled bomb, Little Boy, on Hiroshima, only 10% of the large city remained. Even with the bomb missing its target by over a kilometer, 30% of the population, over 80,000 people, were killed. Even more citizens died from radiation after the immediate bombing. After this bomb was dropped on Hiroshima, Japan's emperor did not surrender, and Harry Truman had to drop another bomb. On August 9, just three days later, another bomb, nicknamed Fat Man was dropped on the port city of Nagasaki. Fat Man
Enrico Fermi of Italy irradiates uranium with neutrons. He believes he has produced the first transuranic element, but unknowingly achieves the world’s first nuclear fission.
Finally, the day came to test out the first atomic bomb, ‘The Trinity Gadget” a plutonium impulsion type bomb was going to be tested in a remote corner on the Alamogordo Bombing Range known as the "Jornada del Muerto" or "Journey of Death", 210 miles south of Los Alamos. The researchers were at the time worried that the bomb would ignite the atmosphere and either destroy the world or all New Mexico. In reality the scientist’s calculations concluded that it was highly unlikely for this to happen, but many people aware of the potential power of the bomb were anxious. And at exactly at 5:30 a.m. July 16, 1945 the Trinity bomb went off and was a success that ushered in the Atomic age. “The Gadget” materialized a mushroom cloud of radioactive vapor 7.5 miles high. Beneath the cloud, all that remained on the ground at the blast site were fragments of green radioactive glass created by the heat of the reaction. Now that “The Gadget” was proven a success, it was time to apply atomic bombs in war. About three weeks later “Little boy” and” Fat Man” were dropped on Hiroshima and Nagasaki, destroying a large part of the city. Little boy was the first atomic bomb to be used in
