Ukraine is the big enchilada . I believe i've put together enough information ( just like i did with Libya)
to show Crimea was a reaction to the threat to Sevastopol. The lease was signed then Poroshenko did what all the Orange types did. go wobbly on it
Donbass is Russian separatists - not Russian troops before this invasion
Belarus is tied to Russia because of western threats.not some messianic vision
You seem to think Putin is this demon weaving a web for his vision
In fact his strategy is grounded in realpolitik:
https://en.wikipedia.org/wiki/Belarus–Russia_relations#2000s
the strategic value of Belarus seemed to continue to rise for Russia because of the international developments. These activities included the United States military activity in the post-Soviet space since the September 11 attacks in 2001, the eastern European states shift towards the west, the plans to deploy NATO's missile defense system in Poland or the Czech Republic, and above all the rise of the colour revolutions. As a result, despite setbacks in political and economic integration, the military-integration processes between the two states continued.[6]
As Russia realized that a full integration with Belarus would be costly, it shifted its foreign policy towards a more pragmatic direction. Two major goals were distinguishable in this policy — The first was to reduce the economic burden which Belarus laid on its economy and the second was to take over the energy transit infrastructure in Belarus. These two goals have influenced most of the conflicts and Gas Wars between the two countries.
