Ever thought that maybe the ‘Stans and Chechnya have had enough of being used by Russia as expendable cannon fodder for the illegal invasions of former SSRs that insist on being independent of Moscow?
Maybe they’re remembering the key word “independent” in the setup of the Commonwealth of Independent States. If Russia wants mobilisation to prop up its illegal annexations then Russia should use its own citizens from St and and Moscow.
Nobody mobilizes Kazakhs, they flock en-masse themselves, to earn green card and free college. Chechens are a specific culture who’d rather cover themselves with glory in battle than waste their time in office. Chechens generally hate the West, they believe stroked separatism in their country to their detriment. The same would be said about Ukrainians in a decade.
