Even though the choice between Europe and Eurasia is Ukraine’s to make, others are trying to help her. The Russian Customs decision last Tuesday to subject all Ukrainian imports to meticulous border checks may incur losses worth billions of dollars. The Russian president’s recent attempt, during a visit to Kiev, to sway his Ukrainian colleague toward a choice in favor of the Eurasian Union has evidently proven futile. Now Moscow is trying to achieve the same goal by pressuring its would-be partner. The result is likely to be similar.

Ukraine, still heavily dependent on the Russian market, will definitely suffer. In playing hardball against its neighbor, Russia will also sustain some damage. The net result, however, will be a rekindling Ukrainian nationalism and a semblance of national unity in Kiev. This will not last, of course, as Ukrainian elites will continue with their favorite games. European politicians and the media—those not on vacation in this silly season—will criticize Moscow’s manhandling of Kiev, but will hardly go beyond that. Yet, since any serious integration is a voluntary process, Russia can but lose the game.
