The MENA region has long been shaped by instability, recurring conflicts, and external interventions. Despite the presence of IOs claiming to safeguard peace and security, neither the UN nor the NATO has been able to fully meet these goals. This chapter explores the scholarly debate of these institutions in shaping the trajectory of Türkiye-Libya relations, situating the discussion within broader debates on security, power, and hegemony. While the literature on Turkish–Libyan ties is extensive, it often neglects the influence of IOs that formally operate under the framework of peace and security but in practice are deeply entangled with power politics and the global defence industry. Drawing on a CSS perspective, the chapter highlights how hegemonic structures within the UN and NATO often reproduce insecurity rather than alleviate it, raising questions about the gap between normative principles and political realities. The review is structured into four parts: theoretical debates on influence and hegemony; the historical evolution of Turkish–Libyan relations; the impact of UN and NATO policies on bilateral dynamics; and the cultural-political role of the Kuloghlis in the Maghreb as a case of overlooked local existence. Methodologically, the study combines secondary scholarship with primary sources from international and national archives, while acknowledging the constraints of limited Libyan archival access. By integrating CSS with historical analysis, the chapter seeks to provide a nuanced understanding of how international organisations shape, and at times distort, regional relations, demonstrating that peace and security remain more of a theoretical promise than a lived reality in the MENA context.
