yes but their was no other person like Hitler in Germany. Hitler was obviously the top dog of the Nazis and the only alternative was either Communist or another Wiemar crackpot with nothing of any substantive agenda but to get unemployment under control. Their was nobody who preached “they stabbed us in the back mentality” except the Nazis.
Of course if Hitler was dispatched early in 1939, Goering would be the new leader ( it was already the decree in that event)
Goering would have been worse than Hitler.
If Goering was gone then… their is a real chance for something different. Most likely Admiral Raeder or Donetz or even Manstein may have been the leader and a real chance to win was available.
so it would take bumping off the top 2 Nazis to accomplish your idea
