In the past, imperial and colonial governments provided resources to minority groups and encouraged people to identify with them, so as to enhance the government’s ability to divide and rule. The governments of nation-states, in contrast, attempted to promote the unity of their people, the development of national consciousness, the suppression of subnational regional and ethnic loyalties, the universal use of the national language, and the allocation of benefits to those who conform to the national norm. Until the late twentieth century, American political and governmental leaders acted similarly. Then in the 1960s and 1970s they began to promote measures consciously designed to weaken America’s cultural and creedal identity and to strengthen racial, ethnic, cultural, and other subnational identities. These efforts by a nation’s leaders to deconstruct the nation they governed were, quite possibly, without precedent in human history.
These words are from Samuel Huntington's “The Clash of Civilizations”, published in 1993 and explain why Trump won.
Reading the essay 24 years after it came out, it is full of fascinating things. Like these.
... while the elite of Turkey has defined Turkey as a Western society, the elite of the West refuses to accept Turkey as such. Turkey will not become a member of the European Community, and the real reason, as President Ozal said, "is that we are Muslim and they are Christian and they don't say that." Having rejected Mecca, and then being rejected by Brussels, where does Turkey look? Tashkent may be the answer. The end of the Soviet Union gives Turkey the opportunity to become the leader of a revived Turkic civilization involving seven countries from the borders of Greece to those of China. Encouraged by the West, Turkey is making strenuous efforts to carve out this new identity for itself.
During the past decade Mexico has assumed a position somewhat similar to that of Turkey. Just as Turkey abandoned its historic opposition to Europe and attempted to join Europe, Mexico has stopped defining itself by its opposition to the United States and is instead attempting to imitate the United States and to join it in the North American Free Trade Area. Mexican leaders are engaged in the great task of redefining Mexican identity and have introduced fundamental economic reforms that eventually will lead to fundamental political change. In 1991 a top adviser to President Carlos Salinas de Gortari described at length to me all the changes the Salinas government was making. When he finished, I remarked: "That's most impressive. It seems to me that basically you want to change Mexico from a Latin American country into a North American country." He looked at me with surprise and exclaimed: "Exactly! That's precisely what we are trying to do, but of course we could never say so publicly." As his remark indicates, in Mexico as in Turkey, significant elements in society resist the redefinition of their country's identity. In Turkey, European-oriented leaders have to make gestures to Islam (Ozal's pilgrimage to Mecca); so also Mexico's North American-oriented leaders have to make gestures to those who hold Mexico to be a Latin American country (Salinas' Ibero-American Guadalajara summit).
Historically Turkey has been the most profoundly torn country. For the United States, Mexico is the most immediate torn country. Globally the most important torn country is Russia. The question of whether Russia is part of the West or the leader of a distinct Slavic-Orthodox civilization has been a recurring one in Russian history. That issue was obscured by the communist victory in Russia, which imported a Western ideology, adapted it to Russian conditions and then challenged the West in the name of that ideology. The dominance of communism shut off the historic debate over Westernization versus Russification. With communism discredited Russians once again face that question.
