The European Union’s fractured response to the Russo–Ukraine War is critically examined, highlighting how internal divisions have reshaped Europe’s security framework. The analysis explores the emergence of the British- and French-led Coalition of the Willing, a response to the EU’s fracturing unity, and assesses its limited prospects for success. Despite early rhetorical solidarity, growing dissent among EU member states, most notably Hungary, Slovakia, Italy, and the Netherlands, has exposed deep political and fiscal fault lines. Against this background, the chapter evaluates President Macron’s strategies and the Coalition’s inability to compensate for the absence of decisive US leadership. Meanwhile, the US Minerals Deal proposal underscored a stark divergence in Western priorities, signalling a shift from security commitments to economic interests. As sanctions against Russia falter and European support for Ukraine diminishes, the Coalition of the Willing appears increasingly symbolic, lacking the strategic coherence or resources to alter the conflict’s trajectory. Ultimately, the chapter argues that Europe’s geopolitical fragmentation raises fundamental questions about the future of its security order.
