“Korea-U.S. Relations: The Politics of Trade and Security,” edited by Robert A. Scalapino and Hongkoo Lee explores the complex and evolving relationship between South Korea and the United States during the late 20th century. The volume highlights two central themes: Security Alliance – The U.S.-Korea military relationship, rooted in the Cold War and the Korean War legacy, remains a cornerstone of regional stability. However, questions arise over the long-term U.S. military presence, shifting security threats, and the need for greater South Korean autonomy in defense; Trade and Economic Frictions – Rapid South Korean economic growth and increasing exports to the United States created tensions, especially over trade imbalances, market access, and industrial policy. These issues sparked debates over fairness, protectionism, and the adjustment of both economies to global competition.
