Power in general theory is defined as having three forms: coercive, utilitarian, and normative. In international relations, emphasis is placed on the first two to the neglect of the third. In this paper, the term "diplomacy" is used for normative power in international relations. Diplomacy is related to three policy making stages and to five dimensions of power. The purpose is not empirical research or theory building but a better public understanding of foreign policy. Southern Africa in the administrations of Jimmy Carter and Ronald Reagan is used as the principal case study. The document concludes with an 84-item bibliography. (Author/CFR)
