The United States and the Republic of Korea have managed to forge a strong working relationship both in wartime and in peacetime, despite an inequality in power between them, through fulfillment of their respective responsibilities. Chay explores how Korean and American actions and inaction affected relations between the two and within the international context of the Korean War. He focuses on how and why war might have been avoided or resolved differently as a result of poor choices and missed opportunities. Using Korean sources, as well as Chinese and Russian materials, this study provides valuable new insights into the relationship between these two unequal powers.
