Pearl Harbor was one of the most vicious attacks on American soil. The surprise attack by Japan took place on Sunday morning December 7, 1941. Japan wanted to immobilize U.S.'s Pacific fleet and destroy any chance of a counter strike in from the Pacific. The United States responded by creating Japanese-American Internment Camps, which uprooted tens of thousands of Japanese-American families. And later America decided to use atomic weapons to end the war with Japan. .
Tension between Japan and the United States started in 1931. Japan had taken over Manchuria, which was then a part of China. In 1937 Japan had started a campaign to conquer the rest of China that was long lasting and didn't work. In 1940 Japan signed the Axis Alliance with Germany and occupied all of Indochina the next year. The U.S. was worried by Japan's movements because of economic interests that the United States had in East Asia. The U.S. strengthened military aid to China and increased financial aid. They also built up the military in the Pacific. The U.S. also cut off shipments of oil and raw materials to Japan. Japanese government saw this move as a threat to Japan's survival because Japan doesn't have many natural resources. Japan's next plan was to take control of the territories of South East Asia that have good amounts of natural resources, even though it would start a war with the United States. (Lord,Walter.

The only thing that stood in the way of this plan was the threat posed by the U.S. Pacific fleet stationed in Pearl Harbor, Hawaii. Admiral Isoroku Yamamoto, the leader of the Japanese fleet, was the mastermind behind the plan to cripple the U.S. fleet. Yamamoto wanted to disable the U.S. Pacific fleet by destroying enough ships, airfields, runways, planes, support facilities, and 4.5 billion gallons of fuel so that there was no chance for a counter attack.
