“Russia has more than 92,000 troops amassed around Ukraine’s borders and is preparing for an attack by the end of January or beginning of February, the head of Ukraine’s defense intelligence agency told Military Times.” https://militarytimes.com/flashpoints/2021/11/20/russia-preparing-to-attack-ukraine-by-late-january-ukraine-defense-intelligence-agency-chief/
Russia will attack at precise moment when time, winter and the Ukrainians will be doing their job for them?
I doubt that
I think Russia wouldn't invade but just push back ukrainian army from the front and oblig them to sign a piece treaty with Donbass. Second step, if it fails, could be precision attacks and air superiority over Ukraine. Final would be the invasion.
Russia went on record that if there's any intervention by them it will be of such magnitude that the Ukraine will cease to exist as a nation
That's what stopped 404s from trying anything last time
We are talking about complete no fly zone over the Ukraine, Syria style air campaign on steroids for months/years, total annihilation of anything that carries weapons including the police, partitioning the whole place in many easily manageable components and arranging for loyal locals to take political and security control over their respective colonial territories to rule as they see fit as long as Russian interests are fully adhered to
All this before any Russian land vehicle is even switched on let alone moves across the border (if they even bother at all, I think it will be strictly VKS gig)
