I'm sorry, but counterfactuals is not something we allow in this subreddit. We try to keep this sub as academic as possible and since what if/counterfactuals are highly frowned upon in academia and can only be based on speculation, we have decided not to allow them here.

Ahh one more thing, could the Germans have done anything to convince the Japanese to attack Russia from the east?

Sorry, but your submission has been removed because we don't allow hypothetical questions. If possible, please feel free to rephrase the question so that it does not call for such speculation, and resubmit Otherwise, this sort of thing is better suited for /r/HistoryWhatIf.
