Yeah, there's this, and you have to consider Uranium, too, I think. Kazakhstan is important for Uranium in some way. Supplier, maybe.
Remember the Uranium One theory floating around that claims threat Hillary/US would sell Uranium to Russia, but keep some of the same batch? That theory maintained that he part kept would be used to make a bomb that would be detonated, and, since Uranium batches have unique fingerprints, would be "traced back" to Russia. That was one of the theories for explaining how Hillary would get her war started.
So, maybe uranium for Iran that specific powers want cut off, or Putin protecting his country's ass from a dirty bomb FF are all on the table. The latter could be why the Russians are moving in pronto like.
Deeper than it seems, I think.
You might say that having the vaxxed/unvaxxed battle play out in demonstrations is good cover for foreign actors. That is, the real purpose of the Kazakhstan events are being undertaken under the cover of a covid restriction protest that was provoked, not organic. The Kazakh government threw in the towel because they knew they wouldn't win, if you ask me. You could say because they knew who/what they were up against.
