Ukraine is a bankrupt, underdeveloped country with no regional/global influence and zero allies. It's a ****hole by any standard... wealth, gdp, level of happiness, crime, you name it. That's what Russia partially 'conquered', along with that other bastion of power, Georgia. Pathetic. Land mass means bugger all, Russia's the largest country in the world and its economy is smaller than Italy's.
The Russians are indeed used to taking rubbish from their leaders but, as the Soviet's or the Tzar's fall proved, there a limit to how much people will take. I think Russians care for the well being of their loved ones, they care for peace and prosperity, just like everyone else. When your economy is shrinking at 2% per year, when the public discourse is dominated by hate against other nations, sexual minorities and political opposition, stability is an illusion. It's the same stability Syria used to enjoy..
