You are full of shit. I’m talking about enemy combatants in a war zone- not in the US. You’re getting off in the weeds. They were not POWs . They were non hostile immigrants . If they were US residents ( one one Or more germs parents) they were called interment camps. There were four ( not 500) containing a TOTAL of 1,200 Germans. Here’s the cliffs.
“Shortly after the Japanese
strike on Pearl Harbor, some 1,260 German nationals were detained and arrested, as the government had been watching them.
[26] Of the 254 persons not of Japanese ancestry evicted from coastal areas, the majority were ethnic German.
[27] During WWII, German nationals and German Americans in the US were detained and/or evicted from coastal areas on an individual basis. Although the War Department (now the Department of Defense) considered mass expulsion of ethnic Germans and ethnic Italians from the East or West coast areas for reasons of military security, it did not follow through with this. The numbers of people involved would have been overwhelming to manage.”
