No, the ethnic Russian elite there may want to turn their back at Moscow-if they conclude that there is more to be gained! Look at Algeria under the French!
I'm not a racist- that fact is an indication of political changes that reflect local demographics.
WRT STOVL LHA/CVs, I never said that they are absolutely, 100% going to build them- there is a high possibility of it, given the factors mentioned earlier, even if there are no indications of it yet.
Again, an irrelevant comparison: even more, one which is almost exactly the opposite of what you seem to think it is. The pieds-noirs were a minority of the population of Algeria (ca 13%), not like the Russians in Siberia & the Far East, who are most of the population, and were facing an insurgency among the Arabs & Berbers who made up most of the population. Again, unlike Russia, & unlike what you posit. The May 1958 rebellion was an attempt not to achieve independence, but against it, i.e. almost exactly the opposite of the scenario you posit, as was (even more explicitly, since France had just agreed to self-determination for Algeria) the failed 1961 putsch, & the OAS.
Personally, I can't imagine the Russian population of Siberia & the Far East deciding they'd be better off run from Beijing (& that's how it'd end up, in fact if not in name, if they were dealing with Beijing as an independent state) than from Moscow. Beijing is too close, there are too many Chinese, & the local politicians & businessmen would rightly fear being squeezed out.
You said there's a high probability of something for which there are no indications, although for it to be possible in the next 15 years, it would have to have already begun. Hmm. Rather a tenuous connection with reality, methinks.
