If you follow this logic, Ukraine should be bombing Moscow right now, and annexing Russia because there are millions of Ukrainians in Russia.
Ancient Kievan lands... 1000 years ago, since before Moscow even existed.

So Turkey should be invading Bulgaria and Crimea, lol.
Complete madness. I wish we had a time machine so that we could send all these autocrats to the 11th century where they belong.
Yes! that's it!, here's my proposal:
Russian will rename to their old name "Russians of Kiev", Turkey will become the Ottoman Empire or even better, Byzantium and go back to from naming Istanbul to Constantinople. We will look for people to be the new Mongols and threaten Europe (they did a much better job than Putin) and we will mix that with the Brigands, Goths, Celtic tribes, Normans, ... we can even have a Crusade! Oh, I forgot... we have to revive the Cossack cavalry or Europe would just not be the same.
Oh Lord Wellington where are thou!
I am such a diplomacy genius...
