It was one of those NPR-ish podcasts. I was thinking This American Life, but someone else said there was a Radiolab episode about it, which I have also been listening to for a long time. Definitely not one of the conversational ones that are more popular now, something produced in a storytelling way.

I listened to a whole podcast episode years ago about German POWs in the U.S., where they started being shipped when the U.K. started running out of space and resources for them. By most accounts, the POWs thought they had it pretty good. They were given paid work in factories and farms and often made friends with the locals. It seems like they were mostly just happy to be out of the war and well fed. They had camp bands, sports clubs and the like. I think most of them were just poor kids who had been conscripted; the actual Nazi ideologues were held in much more secure prisons.
