The racist President Roosevelt interned Americans of Japanese heritage in prison camps...should his statue be taken down? Internment of Japanese Americans - Wikipedia The internment of Japanese Americans in the United States during World War II was the forced relocation and incarceration in camps in the western interior of the country of between 110,000 and 120,000 people of Japanese ancestry, most of whom lived on the Pacific coast. 62 percent of the internees were United States citizens. These actions were ordered by President Franklin D. Roosevelt shortly after Imperial Japan's attack on Pearl Harbor. Japanese Americans were incarcerated based on local population concentrations and regional politics. More than 110,000 Japanese Americans in the mainland U.S., who mostly lived on the West Coast, were forced into interior camps. However, in Hawaii, where 150,000-plus Japanese Americans composed over one-third of the population, only 1,200 to 1,800 were also interned. The internment is considered to have resulted more from racism than from any security risk posed by Japanese Americans. Those who were as little as 1/16 Japanese and orphaned infants with "one drop of Japanese blood" were placed in internment camps.
