Russian leaders have reason to regard Ukraine and Belarus as being within Moscow’s rightful sphere of influence. Indeed, those two nations are within Russia’s core security zone, and the Kremlin will likely go to great lengths to prevent an even bigger NATO military presence on its borders than the one that exists now.
The West is trying to engineer popular opinion in Belarus towards a “color revolution,” fairly obviously. But they are on a sticky wicket. Western Ukraine was genuinely enthusiastic to move towards the west and the EU, in the hope of attaining a consumer lifestyle. Outside of central Minsk, there is very little such sentiment in Belarus. Most important of all, Belarus means “White Russia,” and the White Russians very strongly identify themselves as culturally Russian.
