MOSCOW – Vladimir Putin’s regime is warning Russians that their budding “Snow Revolution” will be as big a mistake as Ukraine’s Orange Revolution of 2004. But, while the similarities between these two popular movements are palpable, their differences are essential, so comparing them might help the Russian opposition to avoid some mistakes. Like the Snow Revolution, the Orange Revolution was a broad middle-class reaction against corruption and the absence of the rule of law. In contrast to the Arab Spring, the Orange Revolution was entirely peaceful, as the Snow Revolution has been, and neither was triggered by economic or social crisis. In 2004, the Ukrainian economy grew faster than ever, by 12%, and Russia’s GDP increased last year by a respectable 4.3%.
