Wonder how WW2 would've shaped out if Stalin had become part of the Axis powers?
Also, i.m.o., I really don't think the russians were our "Allies". I think he was part of the war because Hitler and his nazi group decided, "Oh hey, now that we've got nearly all of western Europe, and the brits in a small pocket, why don't we just eff with Stalin and see if he and his pre-WW1 buddies can try to 1up us.", while doing their blitz offensive.
