Russians Invading Ukrane?

i would like to tempt mel ferguson and char m master to give an estimate of the probability of russia invading ukrane this year. Bonus points for estimates on the probability of such ation extending beyond the danbes. I think it's highly unlikely that the russians think they're going to get even 20 % of what they've asked for. And remember, although putnis is intent on maximising his own legitimacy and playing to russian nationalism, there's a limit to how many dead rRussians he can sustain. It's not as if his popularity is that profound.
