Nothing to gain from deposing a government that signed a belt and road deal a few months ago? Nothing to gain by destabilizing a nation sandwiched between the 2 most populous nations on earth just as their relations are getting better? That's bad analysis.
Even if there is "nothing to gain" the color revolution machine got its funding cut a few months ago. All the little terrorist cells that have been getting that funding are going to lose their jobs. All those little orgs are planning to go out with a bang so they can put it on their resume so they can get an official job at the CIA.
