Apparently not, and from what I hear about the eastern front from those who have recently served there, those so-called "rebels" are incompetent thugs, regularly routed by Ukraine's troops, while even the Russian troops sent in (with the exception of Russian special forces) aren't any better than Ukraine's increasingly proficient military. Of course the latter was gutted by years of neglect under the rule of Moscow's satrap in Kyiv, Yanukovych - but that is changing. While I don't disagree that the Russian Federation (sic) could occupy all/most of Ukraine if it wanted to wage an all-out war it would find itself choking on a very hard candy, for Ukrainians have a long (and proud) history of resisting Russian/Soviet imperialism. Russian forces are not winning the war in eastern Ukraine, which they started, only to fulfil the imperial dreams of the KGB man in the Kremlin.
