Kenny: Putin has said he's pulling back this troops. He doesn't want to spill blood, that's what he says so far. I can't see how that would happen given that both countries have nuclear weapons. If Russia started to disintegrate and there was nobody fully in charge of those nuclear weapons, that would be the time for China to strike. There are territories of Russia that China would like to have under its control. And that's one of the fears in Russia if Russia gets too weak.
