P.S. So funny, you complain you don't get the logic, and I get downvoted for explaining it, rather than calling names.
I suspect that the president has realised that the police and army are not entirely on his side, so is wanting to have some "loyal" troops to send round and kill the protestors, in a way that the domestic troops are less likely to.

Even though Kazakh president does become dependent on Russian forces to some degree, I don't see how 3000 soldiers can control a country with an army of 100,000, National guard of 32,000 and 86,000 policemen. It may give an upper hand, but against whom? There's even no organized opposition.
If you make paragons Czechoslovakia uprisings in 1968, then USSR sent 500,000 soldiers and 5,000 tanks in a 10 times smaller country.
So it was 3 orders of magnitude larger intervention than this.
Using a military treaty in case of a popular unrest may be illegitimate, but it's nowhere near a puppet state.
