The Russian invasion of Ukraine did something to European identity that decades of integration summits could not: it made the identity felt. Geopolitical pressure is, historically, the most reliable accelerant of collective identity formation. Europe had been drifting toward comfortable ambiguity about what it stood for. Russia’s decision to wage a full-scale territorial war on a European neighbor clarified the question with brutal efficiency. The response was not uniform. Hungary maintained its equivocal position, demonstrating that the pressure was not absolute.
