No.
I think any nuclear armed nation that actually had its home territory invaded by an expansionist enemy might actually follow through on a threat to use nuclear weapons in defense of itself. So I think all the scenarios about a Chinese plan to literally invade Russia are wrong. And that's the exact same reason Russian claims that NATO expansion presented a "threat" to Russia were bogus from the start. Everybody knows that is a potential trigger for nuclear war, and there's no invasion whose fruits outweigh that.
@Maj. Bill Martin Ok,but keep in mind that the Chinese care even less about casualites,other than leadership casualities,that is,than the Soviets,there is an awful lot of wealth and natural resources there that the Chinese need. Plus it is virtually unoccupied by the neo-Soviets,so it would basically be a walk-in by the Chinese.
Face it,the Soviets look like Mother Teresa compared to the Chinese,and by the time this current war ends,the Russians will for all practical purposes be out of soldiers and out of weapons other than nuclear.
So,I guess the question to be asked is "Are the Neo-Soviets so desperate they would be willing to go nuclear with China to maintain control over a vast wilderness with assets they are unable to exploit?
I ask this because by the time their war with Ukraine ends,win or lose,they will have lost so many men and so much military equipment they will be incapable of forcing the Chinese out of Russia.
Sure,they can go nuclear,but so can the Chinese,and the Neo-Soviets will still lose.
MY best guess is the Chinese MIGHT offer a purchase plan to the Neo-Soviets that gives them a percentage of the take from the mining and timber operations. That way both could avoid war,and the Neo-Soviets can replenish some of the money they lost in Ukrainie.
Don't forget,the Neo-Soviets control their media even more than the left controls ours,so what they want reported inside the USSR is what WILL be reported.
