South Korea's phenomenal rise has been studied extensively by political scientists and economists both in terms of its impact on democratisation and as a role model for economic development. Yet little attention has been devoted to exploring the nexus between economic development and foreign policy. As a rising middle power, analysis of South Korea's foreign policy is crucial to our understanding of the power structure and future relations in East Asia.

"Washington has long provided a credible security guarantee along with its declaration of the nuclear umbrella in part, in return for South Korea forgoing a nuclear option. South Korea's acquisition of nuclear weapons would remove the rationale for the extension of U.S. nuclear deterrence and undermine the U.S. security commitment to Seoul."

For sixty years, the United States has maintained an extensive network of military bases on the Korean Peninsula to ensure South Korea's security. An alliance that lasts for over half a century is likely to evolve as power configurations and the security environment change; this has certainly been the case for the U.S.–South Korea alliance. This chapter examines the key dimensions of this evolution as they alter the U.S. military presence in South Korea.

For many years, South Korea was largely a consumer of security, protected and supported by the United States and others to ensure peace and stability on the peninsula. South Korea's economic takeoff and ascent as a rising middle power has changed these circumstances and as the years progressed, the Republic of Korea increased its contributions to international peace and security becoming more of a provider of global security than solely a consumer. Two areas where South Korea has made particularly important contributions have been in international development assistance and peace keeping operations.

An equally likely candidate for starting a conflict between North and South Korea is a disputed maritime boundary called the Northern Limit Line (NLL) drawn in the Yellow Sea (West Sea). This seminar examined the roots of the dispute, the economic, international law, and security dimensions of the issue and explores possible solutions to the problem.

"South Korea's record of economic development over the past 5 decades has been phenomenal, and Seoul has used some of this wealth to make significant contributions to international development assistance. ROK contributions to foreign aid are impressive and have grown significantly despite the lingering economic slowdown, but there's more to be done. The ROK government continues to increase its assistance working to reach levels commensurate with its economic and political status. As a rising middle power, South Korea is well positioned to make important contributions to global peace and stability through foreign aid...."

A nuclear North Korea makes it crucial that all countries in Northeast Asia work hard at maintaining a stable security environment that avoids the dangers of a crisis while encouraging North Korea to adopt a nuclear strategy that retains its "no first use" pledge, a strong command and control system, and a stable nuclear weapons posture. Given its relationship with North Korea, China is best positioned to encourage DPRK leaders in these directions.

"A military strike against North Korean nuclear facilities would be very dangerous, possibly setting off a chain of events that could wreck the peninsula. South Korea has made absolutely clear that it will retaliate if North Korea initiates some type of provocation but a direct military strike to eliminate its nuclear program is unlikely. Finally, despite some indications of unhappiness with Pyongyang's actions, there are limits to what China is willing to do to exert pressure on North Korea."

"While concern for North Korea's push to become a relevant nuclear power is warranted, it is equally important to recognize the very serious technical issues that have plagued Pyongyang's efforts to date. Building a nuclear weapon and its delivery system, and then keeping them operational for the long term is hard—even harder for those states attempting to do it under the umbrella of international sanctions and monitoring."

The armed forces have always played a vital role for states as their guarantor of national security. In addition, the military has often been a political actor with varying degrees of power and influence over budgets, foreign and defense policy, or a full-blown military dictatorship. Some are also significant players in the state economy. This chapter provides an assessment of the North Korean military's role and influence in all three areas — security, politics, and economics — as the country undergoes its second leadership transition to its young leader, Kim Jong-un.
