In the election of 2016, Donald Trump appealed to citizenship, sovereignty, and borders. This was a direct entreaty to the people as the ultimate source of sovereign authority, bypassing the ruling-class elites that dominate the media and the universities; his appeal also ignored political experts, pollsters, and government bureaucracy. In the postmodern world, the nation-state is under attack everywhere as the source of all evil, the cause of war, selfishness, racism, white privilege, misogyny, homophobia, transphobia, Islamophobia, and all the other irrational phobias that make up the universe of political correctness. The idea of the nation-state itself is said to be irrational and arbitrary.
All of this overwrought criticism of nationalism and the nation-state overlooks a very significant point developed in my new book, The United States in Crisis: Citizenship, Immigration, and the Nation State: the nation-state is the only form of political organization that can sustain constitutional government and the rule of law.
No empire has ever been a constitutional democracy or republic, nor will constitutional government exist in global government. If, as is widely alleged, the dialectic of History is inevitably tending toward global governance and universal citizenship, then it is also tending toward tyranny.
