In his landmark 1981 book, Political Pilgrims: Travels of Western Intellectuals to the Soviet Union, China, and Cuba, Paul Hollander wrote of the hospitality showered on sympathetic Western visitors to the Communist world: the banquets in Moscow thrown for George Bernard Shaw, the feasts laid out for Mary McCarthy and Susan Sontag in North Vietnam. But his conclusion was that these performances were not the key to explaining why some Western intellectuals became enamored of communism. Far more important was their estrangement and alienation from their own cultures: “Intellectuals critical of their own society proved highly susceptible to the claims put forward by the leaders and spokesmen of the societies they inspected in the course of these travels.”
Hollander was writing about left-wing intellectuals in the 20th century, and many such people are still around, paying court to left-wing dictators in Venezuela or Bolivia who dislike America. There are also, in our society as in most others, quite a few people who are paid to help America’s enemies, or to spread their propaganda. There always have been.
