This paper rigorously examines the comprehensive benefits of European integration, focusing on its profound impact on economic and social spheres. The discussion begins by emphasizing the need to revisit the integration discourse through economic, social, and geostrategic perspectives. It underscores the European Union’s foundational role as a political peace project underpinned by economic union, illustrating the significant economic benefits such as enhanced GDP per capita, trade integration, economies of scale, and financial liberalization. Furthermore, the paper juxtaposes EU pre-accession assistance with cohesion funds, highlighting the substantial financial advantages conferred by full membership. The urgency of EU enlargement is discussed, particularly in the context of the geopolitical challenges precipitated by the conflict in Ukraine. The analysis concludes with a call for structural reforms in the Western Balkans to expedite convergence with the EU, emphasizing the importance of regional connectivity, economic resilience, and sustainable development. This integration is posited as a critical pathway to fostering a prosperous future within the European framework.
