Drawing on a diverse range of academic sources, policy documents and security analyses, and employing an empirical qualitative research approach, this study examines the factors that contribute to regional instability, such as territorial disputes, military buildup and hybrid threats. An essential point of this article is Romania’s role in addressing the identified risks and threats. The analysis investigates Romania’s position as a NATO and EU member state and its contributions to regional security initiatives. In addition, it highlights the importance of inter-institutional cooperation and coordination for strengthening Romania’s resilience in the face of complex security challenges. Overall, this article provides not only a comprehensive analysis of the security landscape in the Black Sea region, but also valuable insights into the potential paths that future developments could take.
