Step-by-step explanation:
internment of Japanese Americans in the United States during World War II was the forced relocation and incarceration in concentration camps in the western interior of the country of between 110,000 and 120,000[5] people of Japanese ancestry, most of whom lived on the Pacific Coast. Sixty-two percent of the internees were United States citizens.[6][7] These actions were ordered by President Franklin D. Roosevelt shortly after Imperial Japan's attack on Pearl Harbor.[8]
