Never forget how Japanese = Americans were treated . How come German-Americans weren’t rounded up and interned ?

Cuz they were not WHITE !

[wideawake]

Close to 40% of the white population of America had German ancestry, with several states having more German Americans than any other kind.

Race was a factor, another factor was that neither the Germans nor the Italians had attacked American soil the way the Japanese did, another factor was that German Americans had roots going back to the colonial period, another factor was that something like 80% of Japanese Americans lived in one region (Southern California) and it was an area essential to the war effort.

[Ruy Dias de Bivar]

Might want to look at anti-German sentiment in WWI. Cities names were changed from German spelling to English.
German competitions like Shutzenfest were done away with, some German families homes were confiscated.

Even in England the House of Battenburg became Mountbatten.
