The movement in Ukraine is not the only one to occur in Eastern Europe; it’s just the most spectacular. It was preceded by tremors in Slovenia, Bulgaria, and elsewhere; more recently, Bosnia erupted, though thankfully most of the participants there explicitly disavowed nationalism. Barring world revolution, the crises inflicted by capitalism will continue to provoke social unrest until the emergence of some massive new mechanism of control or appeasement.
In a globalized world, state structures are forced to impose and perpetuate these crises, but are increasingly powerless to mitigate the effects. This makes the state a sort of hot potato; any party holds the reins at its own risk, as Morsi’s downfall showed in Egypt. On the other hand, in moments of crisis, whoever is capable of effective action against the repressive forces of the state will accumulate popular credibility. This is how our present era is anarchist even where fascists are concerned.
Likewise, powerful governments will not stand by and let common people get a taste for overthrowing them. They will be pressed to intervene, as Russia has in Ukraine, in hopes that war can trump insurrection. War is a way of shutting down possibilities—of changing the subject. It is a risky business, however—it can help governments to consolidate their power, but history shows that it can also destabilize them.
