Everything you’ve written here is accurate, with the exception of ethnic superiority. The current regime has been arguing that the Ukrainian race doesn’t even exist, that they’re just “little” or wayward Russians, which is why one of their genocidal moves is to steal children to try to prevent their demographic decline.

I mean, that is pretty clearly an assertion of ethnic superiority, just not of racial superiority. Though it dips into racism at times as well - bigotry rarely concerns itself with consistency, as with the historical abduction of indigenous children in North America and Australia.
