In Post #2, nena asked "But what would happen during WW2?"
I have wondered what WW2 would have been like had one of the Allied forces been a strong Tsarist Russia instead of the Communist Soviet Union? I think Hitler would have still come to power in Germany much as he did, and there would still have been a WW2, but there would have been differences.
How would Nicholas II or his son Alexei II as Tsar have handled WW2? Also it would have made for a very different and much more peaceful postwar world, no cold war between The Soviet Union and The West. As they say about history, change one thing and you change everything.
