What was true of japaneese americans in the west during world war II?

On December 7, 1941, the United States entered World War II when Japan attacked the U.S. naval base at Pearl Harbor. At that time, nearly 113,000 people of Japanese ancestry, two-thirds of them American citizens, were living in California, Washington, and Oregon. On February 19, 1942, President Franklin D. Roosevelt signed Executive Order No. 9066 empowering the U.S. Army to designate areas from which "any or all persons may be excluded." No person of Japanese ancestry living in the United States was ever convicted of any serious act of espionage or sabotage during the war. Yet these innocent people were removed from their homes and placed in relocation centers, many for the duration of the war. In contrast, between 1942 and 1944, 18 Caucasians were tried for spying for Japan; at least ten were convicted in court.
