Specifically I'm talking about the western powers here. Russians were generally considered to be untermenschen, and my assumption is that the jews serving in the russian army would have been treated poorly. (If I'm wrong, by any means correct me). However, US and British troops, I've been led to believe, were treated much better. But what about Jewish individuals in those POW's? Were they treated worse than other POWs?
