Russia's invasion of Ukraine brought both condemnation and vindication to the European Union. EU policies were condemned for being complacent, naive and greedy. However, when European leaders conducted a coordinated response backing Ukraine, the war also vindicated the EU as a liberal project. The crisis has led to a surge in support for the EU, unprecedented cooperation across policy areas and new accession negotiations with the EU's eastern neighbours. To understand this shift, the article argues that crisis has catalysed the EU becoming a sceptical liberal actor. Sceptical liberalism is characterized by a bleak view on the trajectory of the international order, a self-critical understanding of Europe's role in it, and a willingness to intervene, including with military means, to tackle political predicaments. The transition changes EU leaders' previous optimistic liberal approach of pursuing peace and prosperity though mediation and interdependence. Distinguishing between ideals and actions, the article argues that liberal ideals remain intact, but a sceptical outlook implies different actions to pursue those ideals. The article's argument challenges longstanding scholarly debates on ‘normal versus normative power Europe’, which build on an excessively bifurcated assessment of EU foreign policy that fails to capture contemporary dynamics and the dilemmas they cause.
