41. Manhattan Project Albert Einstein warns Roosevelt in 1939, that by using uranium “extremely powerful bombs of a new type may …be constructed.” Atomic Bomb program headed by General Leslie Groves. Secret laboratory set up in Los Alamos, NM headed by Robert Oppenheimer July 6, 1945, the 1 st atomic bomb detonated in New Mexico.

42. Dropping of the Atomic Bomb Hiroshima 90,000 to 100,000 persons were killed immediately 145,000 persons perish from the bombing by the end of 1945. Nagasaki Leveled Area: 6.7 million square meters Casualties Killed------73,884 Injured-----74,909 Total------148,793 (Large numbers of people died in the following years from the effects of radioactive poisoning.)

43. Dropping the Bomb Pros 1.The drop of atomic bomb triggered Japan to surrender and this ended the war faster. 2. This gave US superior strength since they have control over the atomic bomb. 3. This incident saves thousands of lives of American soldiers. 4. US become powerful and it has maintained peace with the atomic bomb as the needed leverage. 5. Many nations have witnessed the devastation brought by atomic bomb and this encouraged them to talk about peace talks rather than war. Cons 1.Dropping the atomic bomb enable other countries to start with their nuclear weapon buildup. 2.This incident has destroyed countless Japanese citizens who are innocent and has plagued radiation and serious medical condition like cancer. 3.Millions were spent in the development of the atomic bomb, a larger amount of money that can be use for further priorities should they decide not to allocate this on the atomic bomb preparation and development. 4.Firebombing also cause serious amount of damage. 5.Japan has made serious sacrifices for their power and for the lives of their people. 6.Dropping the bomb also built a wall that divides citizens of both nations. 7.o one can control the means on how the bomb caused devastation and the people that will be killed. 8.The incident has revealed the power that a nuclear weapon can do giving them the idea to utilize this weapon for battle.
