As I said the armed forces of Ukraine should be considered divided at this point. I wonder how much of the indigenous military industrial production has also been divided, I know for example Antinov's headquarters are in Kiev, and that was state run.
I think two factors are critical:
Are the Ukrainian forces hostile to Kiev made up largely of ethnic Russians?
If yes, Kiev government will survive and Putin might carve out a piece of Ukraine, but rest of Ukraine will turn even more wholly pro-west at the conclusion of this and this little show of force not withstanding, Russia is finished as a major power because Ukraine will join NATO and Russian strategic nuclear forces will be progressively checkmated, and Russia now is too poor to afford anything else that would make her more than a petrol state.
If no, then Kiev government is in a precarious situation. In this case, the key question becomes are the Ukrainian forces hostile to Kiev willing to fire on forces and supporters of Kiev.
If yes, Kiev government is finished. If no, then Kiev government might survive, but would be heavily constrained in what it might do after the conclusion of all this.
