So if all are freaking guilty, then Ukraine is guilty as well, because I'd bet if you took the DNA of every last Ukrainian, you'd find a large number of them have Mongol DNA as well, just like a large number of people in the world today have Neanderthal DNA, and why many Britains have Viking DNA. People migrate, they get around and inter-marry.
Kievan Rus - Viking - Ukraine
Moscovy Swamp - Mongol - Russia
