beyond the rhetoric and propaganda, russia could ill afford 500.000 casulaties over donetsk and luhansk which are two very small regions compared to the overall size ukraine. the only thing that is truly important in this war is control of crimea and the naval base there.  russia is also coming to terms to china taking leading economic role in central asia. these former soviet countries don't give a shit about russia except for energy but are eager for silk road initiative and the brics currency by china. so there will never be a "eurasian state", more like a generalized loose eurasian alliance. there is also the turkey - azerbaijan - fsa syria axis which will stir up trouble for russia in the future as it aims to completely destroy another ex-soviet country that is armenia. so not all is roses and rainbows in that camp.
