The prolonged EU accession process faced by Serbia has been primarily hindered by a significant misunderstanding of the European Union’s nature by the Serbian political elite. Many leaders failed to grasp that the EU project has always been a geopolitical extension of the United States, aimed at maintaining dominance over Europe. This misperception has influenced the EU’s political stance towards Serbia, mirroring Washington’s approach. The breakup of Yugoslavia, influenced heavily by Western intervention, left Serbia, seen as a geopolitical obstacle due to its Orthodox Christian identity and historical ties to Slavic and Byzantine civilizations, in a complex political position. This paper explores the historical context, the dynamics of Serbia’s EU relations post-Yugoslavia, and the future of Serbia–EU interactions, considering the changing geopolitical landscape. The analysis spans from the end of the Cold War to the present, highlighting the impact of EU policies, the influence of US geopolitics, and Serbia’s evolving stance towards European integration.
