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… - 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.

Millions of immigrants and their children achieved wealth, power and status in American society precisely because they assimilated themselves into the prevailing American culture. Hence there is no validity to the claim that Americans have to choose between a white, racist, WASPish ethnic identity, on the one hand, and an abstract, shallow civic identity dependent on commitment to certain political principles, on the other. The core of their identity is the culture that the settlers created, which generations of immigrants have absorbed, and which gave birth to the American Creed.

The leaders of the United States have not only permitted that but assiduously promoted the diversity rather than the unity of the people they govern. The leaders of other countries have, as we have seen, at times attempted to disavow their cultural heritage and shift the identity of their country from one civilization to another. In no case to date have they succeeded and they have instead created schizophrenic torn countries. The American multiculturalists similarly reject their country’s cultural heritage. Instead of attempting to identify the United States with another civilization, however, they wish to create a country of many civilizations, which is to say a country not belonging to any civilization and lacking a cultural core. History shows that no country so constituted can long endure as a coherent society. A multicivilizational United States will not be the United States; it will be the United Nations.
