I think that argument was substantiated pretty well in the other thread but it's up to everyone to read for themselves (it is an argument not a "proof", so all I can do is outline why I think it is the case based on what I know of the topic and let others correct me/add/detract wherever seems relevant). Who was the Russian propagandist? Genuinely can't remember.
Just on this. I didn't raise the POW war crime in this thread, I was posting in reply to a topic that had been discussed, at length, by other posters (carolina red, harms, dwayne, yourself I think, and many more) a day or two ago. I was updating readers of the thread on where the claim now stood (after people were claiming it was outright fake).
But generally, I agree, (and said it a page or two back), that war crimes happen in every war.
