Transcript of The Causes and Effects of the Atomic Bombs: Hiroshima and Na

In a brief summary, an atomic bomb is a nuclear explosive which derives its power from nuclear reactions. It is composed mainly of the isotope U-235 (Uranium), and it has the potential to cause mass destruction.
Why were they invented?
Why were they dropped?
The United States only had two choices: To bomb Japan, or to invade it. Experts estimated that invading Japan would cause 1.7 to 4 millions Allied casualties and about 5 to 10 million Japanese casualties, as well as making the war longer and more expensive. Alternatively, dropping the bombs would result in fewer casualties on both sides, and allied forces hoped it would cause Japan's surrender. Ultimately, the allied forces chose to deploy the atomic bomb.
The Bombs
The two bombs which were dropped were called "Little Boy" and "Fat Man"
Little Boy
This bomb was dropped on August 6, 1945 in Hiroshima, a military and industrial town. Once dropped it killed an estimated 80,000 people, and by the end of the year injury and radiation raised that number to 90,000-140,000.
Japan's Reaction
At the time that the first bomb was dropped, Japan was the only Axis power remaining since Germany had surrendered several months earlier. However, Japan sustained the bombing of Hiroshima and its leader, Emperor Hirohito, refused to surrender. Because of this, the allied forces decided to drop their second nuclear bomb in hopes of ending the war.
The Fat Man
The Fat Man was dropped in the city of Nagasaki, a large sea port and industrial town, just three days after the bombing of Hiroshima (August 9, 1945). The bombing killed an estimated 60,000-80,000 people.
The Causes and Effects of the Atomic Bombs: Hiroshima and Nagasaki
What is an atomic bomb?
The desire to create the atomic bomb was propagated by the discovery that German physicists had learned how to split a uranium atom and thus, could potentially create a deadly weapon. As a result, the Manhattan Project was initiated by President Roosevelt, and its main purpose was to create the uranium bomb before the axis forces.

These two bombs are the only nuclear bombs that have ever been dropped on an enemy during wartime.

Political Effects of the Bombings
The dropping of the atomic bombs, ultimately prompted Japan's surrender on August 15, 1945 and ended the Second World War. Japan was forced to emasculate its military and to adopt a western constitution. Additionally, the United Nations was formed in order to promote international co-operation and it acted as a replacement for the ineffective League of Nations. The power of nuclear weapons also became a significant point of tension between the United States and the USSR throughout the Cold War.
Economic Effects
The dropping of the bombs had devastating effects on Japan's economy since both Nagasaki and Hiroshima were important industrial towns. Hundreds of thousands of buildings were demolished or burned down, transportation systems were destroyed, and many large companies like Mitsubishi were destroyed. It cost Japan billions of dollars and many years to rebuild their industrial powerhouses.

Social Effects
The bombings also had some interesting social effects. Japanese survivors faced stigma and discrimination. Many survivors felt as if they were considered "contaminated" and were "to be avoided". Survivors faced fears of reduced chances of marriage, brought on by the fear that offspring of survivors would be unhealthy due to the radiation that survivors endured.
