There are at least 12 potential pockets of separatism in Russia, and these movements are being brutally oppressed by Kremlin.
The term used by Russian state media for these oppressive special operations by Russian military in Caucasus is 'destroying of insurgent forces'. But, at the same time, on the same TV screens, Russian journalists call pro-Russian separatists in Eastern Ukraine not ‘insurgents’ but ‘militia’ or ‘home guards’. It’s absolutely clear why they do it: Moscow is trying its best to preserve integrity of its fragile empire, but cynically intervenes into internal affairs of Ukraine.
But Putin cornered himself, not realizing that his own country, Russian Federation, is more fragile than it seems. Separatism, which Putin exports to Ukraine, will return to him like multiple boomerangs and can destroy Russia in the nearest future.
