I just remembered that in the TV show Band Of Brother, in the episode 2 there is a group of German POW and one of them says to be from Oregon and came back to the « Fatherland » to complete his duty as his family wanted him to do.
So i was genuinely asking myself how many of those German Americans went back to fight for the Nazis, if any of you do have an answer (maybe numbers etc) I would be really interested in it!
Thanks a lot.
I recall posting in a thread on almost exactly the same question a few years ago. That is here - https://redd.it/8647tg - with links to older responses by /u/coinsinmyrocket, /u/scarlet_sage, and a response by /u/commiespaceinvader. There probably are newer posts that may add to these.
