A mere three months ago, Vladimir Putin probably thought he had scored one of his presidency's greatest coups, when he coerced or persuaded – depending on your perspective - Ukraine's Viktor Yanukovych into abandoning the long-expected initialling of his country's Association Agreement with the EU. Yanukovich's U-turn had, to some extent, been presaged by an earlier about-face – under very similar circumstances – of far smaller Armenia's Sargsyan. And for a while, it appeared that Kiev would sooner or later follow several other former Soviet Republics into the Russian president's latest geopolitical project of choice: the Eurasian Economic Union. The Kremlin probably did expect such a move to invite trouble for someone who, despite an occasionally fraught relationship, had long been seen as "Moscow's man in Kiev". But it probably did not anticipate the ferocity of the wave of indignation that followed, much less foresee Yanukovych's fall, a few months later, as a result.
