Russians decided that the tsar would be overthrown in 1917, that the Bolsheviks would take power, that Lenin would be replace by Stalin, Krushchev, . . . , Yeltsin, Putin.

The US, Britain, France and Japan actually invaded Russia (circa 1918) to try to influence the outcome of a transition of power without success.

None of the transitions I described depended on which leader or which faction had funding from outside Russia. I expect Russian self-determination to continue. Nationalism is a very potent force in most countries, but particularly potent in Russia.

Just because Russia has declined in influence relative to other great powers doesn't mean it will stop exercising self-determination.
