If you mean Putin's regime, then I might dissuade you: Putin, to me, is not the sole, or even core, reason of the war, he's simply a figurehead of the corporatocracy more or less dominated by irascible boomers who seek securement of their funds and power through self-imposed isolation of the country behind the event horizon. Locked-in Russia is much easier for them to work with.

He is, I shall repeat, neither a reason nor crux of this escalation, but a mere indicator of deeper historical dynamics. Waves and cycles in global history rise and fall, the next Kondratiev surge looks incoming, as prophesied since the times of the Great Recession.

Russia can exist as a synergistic entity only under the imperial aegis, which is not good or bad per se, but simply most logical from the PoV of its historical evolution, marked with oscillations between cosmopolitical and autarkic attractors.

Chinese internal market is voluminous enough to survive and thrive even under the autarky conndition (see: dual circulation strategy, 国内国际双循环), whereas Russian is nowhere near breakeven point. However, Russia can't be totally excluded from global economy simply because its exports don't fall exclusively into the hydrocarbons market.
