This thesis examines the evolution of cooperation between NATO and South Korea and categorizes it into two phases: reactive alignment and autonomous strategic convergence. In the initial phase, South Korea’s participation in international security missions involving NATO, such as the war in Afghanistan and anti-piracy operations in the Gulf of Aden, was primarily driven by its bilateral alliance with the United States rather than by a clear strategic plan or bilateral initiative with NATO. Cooperation between NATO and South Korea during this period emerged through parallel participation in U.S.-led initiatives rather than through direct bilateral planning, resulting in functional but limited engagement. Following Russia’s full-scale invasion of Ukraine in 2022 and the increasing coordination among authoritarian states, NATO and South Korea have expanded and deepened their cooperation, which has become increasingly institutionalized. Mechanisms such as the Individually Tailored Partnership Programme and collaboration in emerging security domains reflect a shift toward a more reciprocal and strategically grounded partnership. Drawing on Balance of Threat Theory, this thesis argues that the key driver of this transformation lies in the convergence of threat perceptions. This convergence has strengthened the strategic rationale for deeper cooperation and has contributed to closer linkages between the security architectures of Europe and the Indo-Pacific.
