What needs to happen next is for Russia to split up.

They are sending prisoners, young people and anyone that can hold a weapon, and what they will leave are women I wonder how that will change their country

...and one might think that it's nothing but gravy for the world's security, but there are knock-on effects that are more than possible.

Would Russia*Putin be such a wounded and cornered badger that it*he might lash out with nuclear weapons rather than go down alone? He says so, and maybe we should believe him. If Russia ever does prevail over Ukraine and directly or indirectly initiate a shooting war with a NATO country, estimates of the casualty ratio range as high as 1000 to 1. Nukes much more likely in this scenario. A country of (prewar) 8,000,000 people with an impressive but still limited amount of Western tech is the one in the role of cornered badger, at present. An absolutely shocking turn of events, so what chance would the poor Ivan conscripts have?

Taking Russian oil completely off the market is raising world prices, and, if Xi pays attention to anything at all, China is probably plenty worried. They are at the far end of an extremely long and fragile supply chain, and, in addition to the spectre of No Oil To Buy, any one of a dozen countries have the wherewithal to cut off shipments of almost anything heading to CCP ports and send China into a death spiral. Well, a faster one than it is already in. Would Xi lash out, ala Putin?

They import 80+ percent of their energy needs, and 80+ percent of not only food, but the industrial inputs needed to grow some. I could go on an on about their existential woes, but it's hardly necessary; just the obvious looming catastrophe of massive oil shortages is more enough.

This is not the obvious win of the end of the Cold War. I do find myself rooting for the demise of either or both, at times, but they are very dicey scenarios.
