In Korematsu v. United States (1944), the Supreme Court upheld the military order excluding Japanese Americans from the West Coast on the basis that the action was considered 1. a matter of national security. It was believed that Japanese Americans might try to sabotage US military tactics against Japan despite the fact that many of those interned were second or third generation Japanese Americans with little to no ties to their ancestral country.
