AsianAmericans and concentration camps in WWII essays In the early 1940s, there was evidence of Japanese-American loyalty and innocence, but the information was not always well known. This, coupled with the factors of war hysteria led to the legal upholding of concentration camps in Korematsu v. U.S. (1944). The injustice was clouded, most immediately by the war, and indirectly by racism at home. The sneak attack on Pearl Harbor left a permanent indent on the way Americans viewed the Japanese. Indeed, it was this one act which thrust the isolationist U.S. into the middle of the worlds biggest war. The brutal attack, so close to home, was viewed as sneaky and underhanded. This, added to the fact that the Japanese were rumored to have an amazingly effective spy system on Hawaii and the West Coast, led the Japanese-Americans to become highly suspected individuals. They were even a more immediate threat than communists, since they required an eventual takeover, and Germans, since they were preoccupied by numerous enemies.
