The United States Reaction to the Korean Attack: A Study of the Principles of the United Nations Charter as a Factor in American Policy-Making

Abstract

Little scholarly effort has been devoted to consideration of the part actually played by international law in national decision-making. Diplomatic historians have tended to neglect the legal factor. Political scientists have discussed the rôle of law largely in general terms. The effort of international lawyers has been focused on statement of what the law is supposed to be. Some of this attention might usefully be diverted to study of the place of the legal factor in the making of specific decisions. Such studies should make possible more realistic discussion of the question whether the policy-makers are assigning the degree of emphasis to the factor of international law which is best calculated to promote the national interests and values they aim to serve.What is attempted here is one case study focusing on the legal principles of the United Nations as a restraint and as an incentive to action in the United States reaction to the 1950 Communist attack in Korea. That reaction took two parts: (1) a decision to assist Korea within the framework of the United Nations, and (2) a decision to isolate Formosa from Communist attack by individual American action. After a brief outline of the Charter principles in question, we will consider the way in which each of these decisions was made, together with the domestic and international consequences in each instance.
