The United States South Korea Alliance

How can the United States and South Korea best co-operate to address new security challenges? Can the US-ROK alliance serve to advance South Korea's interests and at the same time help the US to more effectively pursue its own global and regional security objectives? In the context of these questions, the authors explore the possibilities for enhanced co-operation in both traditional and non-traditional spheres.

Against the backdrop of China’s mounting influence and North Korea’s growing nuclear capability and expanding missile arsenal, South Korea faces a set of strategic choices that will shape its economic prospects and national security. In South Korea at the Crossroads, Scott A. Snyder examines the trajectory of fifty years of South Korean foreign policy and offers predictions—and a prescription—for the future. Pairing a historical perspective with a shrewd understanding of today’s political landscape, Snyder contends that South Korea’s best strategy remains investing in a robust alliance with the United States. Snyder begins with South Korea’s effort in the 1960s to offset the risk of abandonment by the United States during the Vietnam War and the subsequent crisis in the alliance during the 1970s. A series of shifts in South Korean foreign relations followed: the “Nordpolitik” engagement with the Soviet Union and China at the end of the Cold War; Kim Dae Jung’s “Sunshine Policy,” designed to bring North Korea into the international community; “trustpolitik,” which sought to foster diplomacy with North Korea and Japan; and changes in South Korea’s relationship with the United States. Despite its rise as a leader in international financial, development, and climate-change forums, South Korea will likely still require the commitment of the United States to guarantee its security. Although China is a tempting option, Snyder argues that only the United States is both credible and capable in this role. South Korea remains vulnerable relative to other regional powers in northeast Asia despite its rising profile as a middle power, and it must balance the contradiction of desirable autonomy and necessary alliance.

A comprehensive look at the role of history, economics, security, threat perception, and domestic politics in the South Korea-United States alliance.

The alliance between the United States and South Korea has endured through seven decades of shifting regional and geopolitical security contexts. Yet it now faces challenges from within. Domestic political turmoil, including deepening political polarization and rising nationalism in both countries, has cast doubt on the alliance’s viability—with critical implications for the balance of power in East Asia. Scott A. Snyder provides an authoritative overview of the internal and external pressures on the U.S.–South Korea alliance and explores its future prospects. He argues that nationalist leaders’ accession to power could put past successes at risk and endanger the national security objectives of both countries. In the United States, “America first” nationalism favors self-interest over cooperation and portrays allies as burdens or even free riders. “Korea first” sentiments, in both progressive and conservative forms, present the U.S. military presence in South Korea as an obstacle to Korean reconciliation or a shackle on South Korea’s freedom of action. Snyder also examines North Korea’s attempts to influence South Korean domestic politics and how China’s growing strength has affected the dynamics of the alliance. He considers scenarios in which the U.S.–South Korea relationship weakens or crumbles, emphasizing the consequences for the region and the world. Drawing on this analysis, Snyder offers timely recommendations for stakeholders in both countries on how to preserve and strengthen the alliance.

On October 18-20, 2001, the 16th Annual Conference of the Council on U.S.-Korean Security Studies was held in Washington, DC. Created in 1985 by retired generals Richard Stilwell of the United States and Sun Yup Paik of the Republic of Korea, the Council's aim was to initiate a conference that would bring together top scholars and practitioners on the most important issues facing the two countries and their important bilateral alliance. Since then, the Council has successfully hosted an annual conference, alternating every other year between meetings in Seoul and Washington. Because of the unexpected attacks on the World Trade Center in New York just 1 month prior to the conference, the papers did not capture adequately an assessment of the actual and potential impact of the terrorist attack on U.S. foreign policy, its implications for the two Koreas, and its probable effects on China and Russia. There were suggestions that the attack would have major effects, but few details about what those would be, which was understandable with so little time having elapsed since the attack. On the other hand, several authors stressed that in important ways much had not changed: U.S. commitments had not been shifted or weakened; the U.S. ability to militarily uphold its commitments had not been affected; and the solidarity of the ROK-U.S. alliance again had been demonstrated through South Korea's strong support for the war on terrorism.

The inconclusive outcome of the Korean War left a peninsula divided between two nations engaged in a deadly cold war. An important aspect of the continuing hostilities was America's security guarantee to South Korea. Despite enormous geopolitical changes brought by the accelerating collapse of communism, the United States has a standing pledge to go to war if necessary to thwart a North Korean attack. This volume assesses the current and future viability of the U.S.-South Korean alliance from military, political, and economic perspectives.

These essays support the argument that strong and effective presidential leadership is the most important prerequisite for South Korea to sustain and project its influence abroad. That leadership should be attentive to the need for public consensus and should operate within established legislative mechanisms that ensure public accountability. The underlying structures sustaining South Korea’s foreign policy formation are generally sound; the bigger challenge is to manage domestic politics in ways that promote public confidence about the direction and accountability of presidential leadership in foreign policy.
