In the 1960s, both academics and policymakers divided the world of nations into three distinct blocs of nation-states whose ranking in each bloc depended upon their respective national economic, political, and social power (Horowitz, 1965). A decade later, however, the events of the intervening years greatly weakened the accuracy of the "Three Worlds" scheme. The First World of Europe, Japan, and North America gradually was coming to pragmatic terms with the Second World of the Soviet Union and the other states that modernized through "socialist revolution." However, the greatest transformation occurred within the Third World of less developed and so-called nonaligned states of Africa, Asia, and Latin America.
