Russia would have been much better off in the long run had they turned to the West in the 90s. Their decline is inevitable, and the past 30 years of opposition has only enabled them to snatch Crimea as a strategically important territorial expansion.
Putin is desperate to save Russia from falling into the depths of history. He knows Russia is no longer as important as the EU so he acting out to show dominance.
It sucks but it's true.
