We don't handle counter-factual questions here (due to their speculative nature). However, you might want to try /r/HistoryWhatIf. Though I'll warn you from experience, this sort of question never goes over well at the various Alternate History subreddits. You'll typically get a lot of answers that boil down to "This scenario couldn't happen" rather than taking the time to figure out a way for it to play out.
