Answer: True
Explanation: During World War II, President Roosevelt signed an order that would see about 120,000 people of Japanese descent, who had not committed any crime, held in an internment camp.
After the bombing of Pearl Harbor, anti-Japanese sentiments grew and the government wanted to prevent people of Japanese descent lending any help to Japan against the U.S. for example, by spying. This was the justification for the Japanese Internment.
