In this study, I analyze NATO's internal cohesion against the backdrop of the war in Ukraine. By examining the differing support levels from its member states to Ukraine, utilizing quantitative methods, I explore the correlation between the support and previously existing groupings within NATO. My findings reveal persistent divisions, suggesting that alliance cohesion has not significantly improved. The study offers crucial insights for Swedish and NATO policymakers, highlighting the strategic importance of understanding alliance dynamics during global crises. It underscores the necessity for policies that enhance unity and effectiveness in international alliances.
