Russia is a serious country; Poland isn’t.
This made the revolution in Ukraine not only a disaster for Russian foreign policy, but a challenge to Putins regime at home. The weakness of Putins policy is that it cannot account for the actions of free human beings who choose to organize themselves in response to unpredictable historical events. Russian propaganda presented the Ukrainian revolution as a Nazi coup and blamed Europeans for supporting these supposed Nazis. This version, although ridiculous, was much more comfortable in Putins mental world, since it removed from view the debacle of his own foreign policy in Ukraine and replaced spontaneous action by Ukrainians with foreign conspiracies.
