The purpose of this paper is to examine the structures of international conflict and 'militarization' in the Third World. The dynamics of the postwar international conflict and conflict structures of the Third World are composed of one world military order. Approximately five hundred sixty four cases of conflict in the post-war world are examined. One of the major findings is that the T-U conflicts (inter-bloc conflicts in Galtung's term) have shown a pattern of unequal exchange and exploitation with the 'nuclear threat' of the 'top-dog' in the background. This can be explained as a structural expression of 'divide and rule' in the contemporary world setting and it should be regarded as one peculiar aspect of 'structural violence.' Structural violence should, however, be grasped in the context of world 'peacelessness' and maldevelopment in arms trade, 'development foreign policy' and authoritarian regimes.
