@DrBeer, damn, that's serious stuff and it explains quite a lot things and why Russia didn't had much problems in Southern Ukraine. I think you don't have to be military expert to expect that Russia will attack from Crimea. It was much more difficult to expect that they will attack from Belarus.
I think it is safe to say that the special operation to eliminate any anti-Ukrainian elements in Ukraine has started.
Ukraine should have done this in 1991 as the Baltic countries did.
Actually, Baltic states haven't done enough to clean up from pro-Russian elements. Former communists were allowed and still allowed to be ellected and work in public sector. So, from communist they have turned into patriots. Most of them don't have pro-Russian views or at least don't show it, but in general they are harmful for country.
I would not be surprised if Ukraine similarly has spies in Russia.
Offcourse they have.
