Final answer:
Other than Japanese Americans, immigrants from Germany and Italy were also suspected as potential enemy agents during World War II, but unlike Japanese Americans, who were interned en masse, those of German and Italian descent were generally arrested for suspected affiliations with enemy organizations.
Step-by-step explanation:
Other than Japanese Americans, immigrants from Germany and Italy were also identified and suspected of being potential enemy agents during World War II. However, these individuals were predominantly arrested based on suspicion of membership within pro-Nazi and fascist organizations, unlike Japanese Americans who were often arrested due to association with community organizations or Buddhist churches. Despite the discrimination and suspicion, only Japanese Americans were subjected to mass internment based solely on their ethnicity. Many of the internees were citizens and had never shown any evidence of collusion or espionage. The military forced around 120,000 Japanese Americans to live in detainment camps for the duration of the war under Executive Order 9066, which resulted from the heightened fears and racial prejudices following the attack on Pearl Harbor.
