I know that this POD has been done to death, but many of the scenarios resulting from it end in unrealistic utopia-wanks.
My challenge is to create a realistic scenario; what do you think would have really happened if FDR had managed to live a few more years after his abrupt OTL departure?
Granted, the world won't be the bleak, hapless disaster heap that it is today, but what would the world actually look like?
Thoughts?
