Atomic Bomb

In 1939 the German born Albert Einstein had informed President Roosevelt about the possibility of creating a powerful bomb. It would produce an extremely powerful explosion by the splitting of an atom. Einstein and other scientists feared that Germany might develop such a bombfirst. In 1942, the United States set up a secret project called the Manhattan Project to develop thefirst Atomic Bomb. Thefirst test explosion of the Atomic Bomb occurred in the New Mexico desert in July 1945.
Roosevelt died in April of 1945, and Vice President Truman became President. Truman met with the British Prime Minister Winston Churchill, and the Russian Dictator Joseph Stalin, in Potsdam, Germany, in July 1945. At the Potsdam conference, a conference between the Allied forces to discuss war options, Truman learned of the successful test explosion of the Atomic Bomb. Truman informed the other Allied leaders that the Atomic Bomb was complete and ready.
The United States, Britain, and China then issued a statement threatening to destroy Japan unless it surrendered unconditionally. In spite of the warning, Japan kept fighting. Japan also did more than continue fighting. Japan, knowing that an Allied invasion was inevitable, began to train its civilians to defend the Japanese homelands.
On August 6,1945, at 9:20 a.m., the American military dropped the atomic bomb on the Japanese city of Hiroshima out of the Enola Gay, piloted by Colonel Tibbetts. This was an extremely controversial event in the United States. Many U.S citizens did not know if the United States was justified in the dropping of the atomic bomb. Historians to this day still criticize the decision that the military made. The reason for this controversy is that it is difficult to predict what would have happened if the bomb were not dropped. In my opinion, the United States was justified in this action, and I have many reasons to support my belief.
The chief reason was that it wo…

Atomic Bomb

The use of the atomic bombs on Japan was necessary for the revenge of the Americans and
played an important role in the Allied victory.The impact of the bombs killed hundreds of
thousands of people and the residual effect of radiation is still killing people today. People still
wonder why the bombs were dropped.The history of the world would have been changed
forever had the bombs not been dropped on Japan.
The atomic bomb took six years to develop and cost about two billion dollars.The most
complicated process in its development was trying to produce enough uranium to sustain a chain
reaction.Thefirst bomb was dropped on the Japanese city, Hiroshima on August 6, 1945.The
bomb dropped on Hiroshima weighted 4.5 tons and the bomb used on Nagasaki weighed 10
kilotons.The single weapondropped on Hiroshima, nicknamed "Little Boy," produced an
explosion equivalent totwenty 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.Three days later a second
plutoniumbomb named "Fat Boy," was dropped on the Japanese city of Nagasaki.The impact
of the bombs on the cities and people was massive. Black rain containing large amounts of nuclear
fallout fell as much as 30 kilometersfrom 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 1.5 mile radius. Within the four square
miles destroyed by the bomb in Hiroshima, 48,000 buildings out of a total of 76,000 were
completely demolished.A mile from the explosion center, where the wind velocity was 190 miles
per hour and the pressure was 1,180 pounds per square feet, all b…
