Yes, it is apparent that Russia, led by Vladimir Putin, is trying to regain control of entire region occupied by the former U.S.S.R. As evidenced by his actions against the Ukraine's sovereignty in the Crimean Peninsula, Putin sees the end goal of reuniting the motherland under Moscow's rule as an end goal of his imperialist adventures.
Russia has been strengthening its military and increasing strong talk about the power of Russia. The country recently unveiled the most massive nuclear weapons the world has ever seen. Russia does all of this to show military might and that any attempt to stop their efforts to regain control of the U.S.S.R will be met with massive deadly force.
It is no secret that Russia has had its eye on the Ukraine for a long time. They never wanted the Ukraine to break apart on its own in the late 1980s and early 1990s. They already just randomly took over part of Crimea. They want to get this done before Obama gets into office. They want control of all of Northern Asia.
That's pretty self-explanatory if you're familiar with the doctrine. If violence breaks out, and sadly I think the Russians are attempting to bait Ukraine into violence, intervention might be legally actionable under the Responsibility to Protect. The Crimean Tatars in particular, considering the hostility Putin has to Sunni Muslims and the general hostility among ethnic Russians in Crimea towards them. But since the UNSC will be deadlocked by a Russia veto, it would require an action by the UNGA to pass a "Uniting for Peace" resolution which would allow action to bypass the UNSC and authorize action under R2P. There is no precedent for it, though the option was part of the original formulation by the ICISS of R2P which was adopted by the UN in 2005. I'm not even sure when the last "Uniting for Peace" resolution was done. But it is the one path past the UNSC.
