One thing that I haven’t seen as a contra-history is what if Hitler hadn’t gone into Europe, but instead looked east and made his first initial advance against Russia. What would be the response be? Tacit acceptance? I don’t see where the rest of Europe and the US jumping to Stalin’s aid would be on the table, and I have a hard time imagining them marching against Germany from the west. I know that the mutual pact between Japan and Germany makes it a non-player, but Germany could have negated or ignored that.

Just a curious thought on my part.
