Ooh, I do like it when stale old Kremlin talking-points get a refresh and a much-needed update. This effort is still pathetically inadequate, but at least it's making an effort. Of course, the fact that Russia is a nation in the thrall of a kleptomaniac regime and ruled by a sad little dictator who is directly responsible for countless war crimes is apparently beside the point, at least as far as this Russian troll is concerned. Of course Ukraine has a problem with corruption, but so what? If corrupt nations are supposedly not worthy of self-determination then Russia should be broken up immediately. Moreover, the USA, Greece, Italy, Turkey and (insert 150 other countries here) should also lose their right to self-determination.
In short, only a moron would pay any attention to the spurious argument presented here - which means it will definitely have some, but limited, success.
