This paper discusses five main patterns of authoritarian government rule that are currently prominent in international society. The first pattern is "Brazilianization" which has evolved as a model for rightist, capitalist elites in the more industrialized countries of the Third World (e.g. Iran, Indonesia, and Argentina). A common feature of these countries is to seek integration into the world trade and money markets including a receptivity to multinational corporations. The paper then turns to a discussion of "Leninization" which is manifest in every Third World socialist society whether it looks to Moscow, Peking, or itself for primary guidance. A third kind of authoritarian tendency examined is "Praetorianization" which occurs in conditions of relatively little industrial development. Such governance patterns can be linked with either capitalist or socialist states but are characterized more by the praetorian exercise of state power than by the ideological orientation of the regime. Following this is a brief appraisal of an authoritarian tendency in the social North known as "Stalinization." Here, the central phenomenon is the persistance of Stalinist modes of rule in the Soviet Union and its East European allies. A short discussion then follows about the fifth pattern "Trilateralization" and the loss of confidence in the capacity of democratic governance to do the job in the developed countries of North America. The paper concludes with a discussion of the linkage of these five authoritarian tendencies to world order prospects. (Author/RM)
