Let us now turn to a different theory: the 'world-system analysis' constructed by Immanuel Wallerstein. Wallerstein, an exponent of the Marxist school of International Relations (especially in its Trotskyist interpretation), on the basis of the doctrine of "the long run" (F. Braudel) and the Latin American theorists of structural economics (R. Prebisch, S. Furtado), developed a model of world zoning according to the level of development of capitalism. This view represents a development of Vladimir Lenin's ideas on imperialism as the highest stage of development of capitalism, according to which the capitalist system naturally gravitates towards globalisation and the spread of its influence over all humanity. Colonial wars between the developed powers are only the initial stage. Capitalism is gradually realising the unity of its supranational goals and forming the core of world government. This is fully consistent with liberal International Relations theory, where the phenomenon of 'imperialism', critically understood by Marxists, is described in apologetic terms as the goal of a 'global society', the One World.
