The leaders of the United States have not only permitted that but assiduously promoted the diversity rather… — Samuel P. Huntington

Cultural and civilizational diversity challenges the Western and particularly American belief in the universal relevance of Western culture. This belief is expressed both descriptively and normatively. Descriptively it holds that peoples in all societies want to adopt Western values, institutions, and practices. If they seem not to have that desire and to be committed to their own traditional cultures, they are victims of a “false consciousness” comparable to that which Marxists found among proletarians who supported capitalism. Normatively the Western universalist belief posits that people throughout the world should embrace Western values, institutions, and culture because they embody the highest, most enlightened, most liberal, most rational, most modern, and most civilized thinking of humankind.

In the emerging world of ethnic conflict and civilizational clash, Western belief in the universality of Western culture suffers three problems: it is false; it is immoral; and it is dangerous. … The belief that non-Western peoples should adopt Western values, institutions, and culture is immoral because of what would be necessary to bring it about. The almost-universal reach of European power in the late nineteenth century and the global dominance of the United States in the late twentieth century spread much of Western civilization across the world. European globalism, however, is no more. American hegemony is receding if only because it is no longer needed to protect the United States against a Cold War-style Soviet military threat. Culture, as we have argued, follows power. If non-Western societies are once again to be shaped by Western culture, it will happen only as a result of the expansion, deployment, and impact of Western power. Imperialism is the necessary logical consequence of universalism. In addition, as a maturing civilization, the West no longer has the economic or demographic dynamism required to impose its will on other societies and any effort to do so is also contrary to the Western values of self-determination and democracy. As Asian and Muslim civilizations begin more and more to assert the universal relevance of their cultures, Westerners will come to appreciate more and more the connection between universalism and imperialism.

One widely articulated paradigm was based on the assumption that the end of the Cold War meant the end of significant conflict in global politics and the emergence of one relatively harmonious world. The most widely discussed formulation of this model was "the "end of history" thesis advanced by Francis Fukuyama. "We may be witnessing, Fukuyama argued, "… the end of history as such: that is, the end point of mankind's ideological evolution and the universalization of Western liberal democracy as the final form of human government." … The future will be devoted not to great exhilarating struggles over ideas but rather to resolving mundane economic and technical problems. And, he concluded rather sadly, it will all be rather boring.

The West won the world not by the superiority of its ideas or values or religion (to which few members of other civilizations were converted) but rather by its superiority in applying organized violence. Westerners often forget this fact; non-Westerners never do.
