Explanation:

Japanese-Americans were already being discriminated against and during the Attack on Pearl Harbor, they had seemed to be a threat to national security.

FDR made the decision to keep Japanese Americans in a secured area where they can supervise them. The Camps were not as bad as nazi concentration camps but still had affected many of the Japanese-Americans living in them.
