The Evolution of US Extended Deterrence and South Korea’s Nuclear Ambitions

ABSTRACT

Extended deterrence has been a main pillar of the security alliance between the United States and South Korea (Republic of Korea [ROK]) since the end of the Korean War. The changing dynamics of US extended deterrence in Korea, however, affected Seoul’s strategic choices within its bilateral alliance relationship with Washington. Examining the evolution of US extended deterrence in the Korean Peninsula until the Nixon administration, this article explains why South Korea began its nuclear weapons programme in a historical context of the US–ROK alliance relationship. This article argues that President Park Chung-hee’s increasing uncertainty about the US security commitment to South Korea in the 1960s led to his decision to develop nuclear weapons in the early 1970s despite the fact that US tactical nuclear weapons were still stationed in South Korea.     

Stochastic allocation of inspection capacity to competitive processes

Optimal allocation and control of limited inspection capacity for multiple production processes are considered. The production processes, which operate independently but share inspection capacity, are subject to random failures and are partially observed through inspection. This study proposes an approach of stochastic allocation, using a Markov decision process, to minimize expected total discounted cost over an infinite time horizon. Both an optimal model and a disaggregate approximation model are introduced. The study provides some structural results and establishes that the control policy is of a threshold type. Numerical experiments demonstrate a significantly decreased amount of computational time required for the disaggregate approach when compared to the optimal solution, while generating very good control policies. © 2002 John Wiley & Sons, Inc.
