The Japanese experience in the United States was rife with discrimination. But the bombing attack on Pearl Harbor on 7 December 1941 by the Empire of Japan caused hysteria among residents along the Pacific coast, where many Japanese Americans lived - including the Nisei generation. The U.S. intelligence found that the majority of Japanese Americans were not security threats and posed no danger to the country. The press, patriotic organizations, and others continued to fuel the fire for their removal from the Pacific coast. On 16 February 1942, President Franklin D. Roosevelt (bowing to political pressure) signed Executive Order 9066; the order caused the evacuation of people of Japanese ancestry from the Pacific coast states. The order uprooted in excess of 100,000 men, women, and children from their homes and farms, jobs, and schools. Forcibley removed, they were interned at ten relocation camps in seven states.
