Almost twenty American naval vessels, eight large battleships and over three hundred airplanes were destroyed by the Japanese on December 7, 1941.

Roosevelt created the Manhattan project after gathering information that the Germans attempted to build an atomic bomb. Unsatisfied, the U.S took an even greater look into their research, in hopes of constructing a more destructible weapon. Years later, when Harry Truman was president, he wanted to abolish the Japanese. August 6, 1945, he did just that. The city of Hiroshima suffered a great loss. An atomic bomb was released upon them, instantaneously killing approximately 80,000 people. Three days later, Nagasaki was attacked when a second bomb was dropped, killing another 40,000 people.

The most secret project in history which involved nuclear weapons was the Manhattan project. Many scientists worked in isolation in different parts of the USA. After the Americans joined the WW2, President Harry Truman threatened the Japanese to surrender or he would unleash the bombs over Hiroshima, in attempt to end the war. The Enola Gay (name of plane) released the first bomb named "Little boy" which detonated 1900 feet over the city. That explosion caused complete devastation for approximately five square miles.
