Putin’s aggression only makes sense against the backdrop of what has been the defining theme of his presidency: turning back the clock. For years that has meant repudiating the transformational policies of his immediate predecessors and reinstating key attributes of the Soviet system within the borders of the Russian Federation. But there were also indications that, if given a chance, Putin might extend his agenda, his rule, and what he hopes will be his legacy beyond those borders. In 2005, he famously lamented that the breakup of the Soviet Union “was the greatest geopolitical catastrophe of the century.” Three years later, Russia invaded Georgia and granted “independence” to two breakaway ethnic conclaves, Abkhazia and South Ossetia. Not until this year, however, did Russia expand by military conquest and unilateral decree its own territory by seizing Crimea. In doing so, Putin also proclaimed the right to “protect our compatriots and fellow citizens”– i.e., Russian-speaking minorities – elsewhere in the near abroad, from Estonia on the Baltic to Kazakhstan in Central Asia.
