The title of this article may promise too much. First, this article will limit itself only to the problems of Socialist states in universal, worldwide organizations, not in all kinds of international organizations, as the title implies. Second, the wording of the title may incorrectly suggest that the unique economic, social, and ideological characteristics of the Socialist system determine the nature of Socialist participation in international organizations. In fact, however, Socialist states act much as other states in their relations with international organizations. Third, the title and content of the article may imply that all Socialist states behave identically in regard to international organizations. It seems necessary, therefore, to emphasize that treating the Socialist states as a group is merely a recognition of the greater community of interests and higher degree of cohesion within the group than between members of the group and states outside it. There remain, however, different viewpoints on some issues among members of the group. Membership in the group may be formal, e.g., participation in a caucusing group, or informal, e.g., sharing in a feeling of responsibility for the welfare of the Socialist world. A formulation of the general attitudes of the Socialist group consists in setting forth policies which result from similar or common economic and social systems, ideology, interdependence, and, last but not least, dangers. In the author's opinion the relevance of establishing and recognizing diese common attitudes despite individual deviations cannot be denied.
