This paper analyses the repercussions that the war in Ukraine since 2022 has had on the European Union (EU) policy of economic globalisation. The Union's comprehensive response to the conflict is examined from different angles, taking in energy insecurity, economic shocks, geo-political shifts, humanitarian challenges and technological vulnerabilities. In this context, the EU's adaptive resilience is evi-dent on several fronts, such as the integra-tion of its economic policies with security (particularly in critical sectors), its role in the European security architecture and its commitment to incorporating Ukraine into the West. The study expands to include the flexible management of mass migra-tion, tech vulnerabilities, energy resilience, economic stability, geopolitical alliances, humanitarian response action and techno-logical reinforcement
