lol, i dont think many people still think germany and nazis are still linked. for instance there are still neo-nazis an many countries. Hitler/nazi part just is a "real" bad guy, and commited horrible atrocities that are fresh enough to make them still "scary". They do make media about other historical slaughters but lets take vlad the impaler.... we can only imagine and put together pieces of what all happened based on records, non photographic pictures etc. We have actual footage of what happened with the nazis.
