Bellicist integration? The war in Ukraine, the European Union and core state powers

Kelemen and McNamara claim that the imbalance between the EU’s strong regulatory authority and weak capacity in core state powers reflects its peaceful origins: the EU lacks coercive force, fiscal autonomy and administrative grip because it never had to confront a serious military threat. Will the emergence of such a threat suffice to correct the imbalance? As I argue theoretically, military threats have ambiguous effects on integration. They can fuel center-formation and capacity-building, as Kelemen and McNamara suggest, but also block it. As I show empirically, the military threat posed by the Russian attack of Ukraine in February 2022 has triggered very little EU capacity-building so far. I observe almost no centralization of core state powers but rather a strengthening of national powers with the support of EU institutions: ‘bellicist integration’ rather than ‘bellicist state-building’.
