What will happen in The Ukraine?

Well, this blog is meant to be about geopolitical predictions, so here is a big one:
Russia will go into The Ukraine again and this time they will go in big.
Why big?
Because the international reaction to them taking the rest of Donbas would be the same as if they invaded the entire country. So if they go in they should go in for everything they want.
In addition, the more audacious their gambit, the stronger the impression they will make on their neighbors and the world.
Why would they go in at all?
I will have to save my reasoning for a later post.
