Donald Trump’s recent proposals to register Islamics living in the United States and to bar more Islamics from entering this country until we can determine how to separate the dangerous ones from those who are not dangerous show that he is the only candidate who understands what a Fourth Generation world will be like. The hysterical denunciations from all other candidates except Senator Cruz demonstrate they don’t get it. While that alone may not be enough to indicate Trump would be a good president, it strongly suggests none of his opponents are fit to hold the office. Whether they like it or not, or understand it or not, Fourth Generation war is what they and this country are facing.

In 4GW, primary loyalties shift away from the state–someone’s native state or one to whch they have immigrated–to a wide variety of other things, including religions, races and ethnic groups, and cultures. Immigrants who do not acculturate are especially likely to become Fourth Generation threats, because they probably will not give their loyalty to a state whose culture is not their own (and to which they may be hostile).

Measures such as those Trump proposed vis-a-vis Islamics will be routine in a world of Fourth Generation war. Any state that wants to survive will have to take them, and stronger actions as well. If a population becomes a base for 4GW on a state’s soil, that state may have to expel them. There may be no other way for the state to perform its primary duty, maintaining order. Any state that cannot maintain order–safety of persons and property–will disappear.

Cultural Marxism forbids us to acknowlege any of these realities, which is why culturally Marxist politicians (Democrats actually believe the stuff; Republicans are too cowardly to challenge it) and institutions such as the New York Times editorial page have frothed at the mouth over Mr. Trump’s entirely reasonable proposals. Cultural Marxism says all cultures are wonderful, peaceful, “vibrant” sources of enlightenment, except our own culture, Western culture, which is evil and oppressive. Defend ourselves against another culture? The very notion horrifies the cultural Marxists; we are instead to embrace it even as it cuts our throats. Cultural Marxism’s goal, after all, from Gramsci and Lukacs onward, has been the destruction of Western culture and the religion from which it grew, Christianity.

Mr. Trump’s proposals do not indicate he has studied 4GW. I would guess he has probably never heard the term. His reactions are instinctive. But they are sound. They reflect reality. If elected, he can leave the theory to the leaders of his Defense Department (we can hope he chooses leaders who do know the theory). He would need only to keep the same instincts under the barrage of conemnation they will bring from the establishment. So far, he seems pretty good at that.

The degree to which the establishment has abandoned all grasp of reality was shown last week in Time magazine’s choice of Angela Merkel as Person of the Year. Merkel will go down in history as Germany’s poisoner, the person who flooded what was a safe, orderly country with carriers of the 4GW bacillus. That, of course, is exactly what cultural Marxism demands, so she is a hero to Time and the rest of the establishment.

Meanwhile, the more Trump insists on confronting cultural Marxism, a.k.a. political correctness, and urges us to face reality, the more his poll numbers go up. The public, it seems, both here and in Europe, want leaders whose feet are planted in the real world. No wonder the shrieks and cries of the cultural Marxists sound ever more shrill. Ideology has no deadlier enemy than reality.
