The Clash of Security and Sovereignty in Quasi-Alliance

Abstract

Abstract Which is needed more: sovereignty or security? The autonomy–security trade-off model sees this as a trade-off between a client and a patron. A client surrenders some measure of autonomy to a patron and, in turn, receives security. This paper explores whether the underlying logic is applicable to quasi-alliances between a state and a multinational regime, such as the United Nations Command (UNC). South Korea has maintained a quasi-alliance with the UNC since the outbreak of the Korean War in 1950. The level of trade-off between South Korea and the UNC, however, has been changing over time, particularly while being affected by the power growth of South Korea, a client, and the preference changes of the US, the most important actor of the UNC, a patron. This paper attempts to explain why South Korea is much more enthusiastic in seeking full sovereignty and more autonomy in the 2018–2019 détente era.
