They began as a Communist think tank at the Goethe University Frankfurt. They noted that the masses didn’t rise up during the First World War to overthrow capitalism; instead, the citizens fought for their countries. Only Russia became Communist, a place they didn’t expect Communism to take hold. Since they took the writings of Marx as gospel, all this was quite shocking. They decided they needed to prepare the way by breaking down traditional social ties—country, family, and religion—and afterwards the masses would embrace rule by a global Communist state. That’s not working out too well lately, but all that’s another story.They found themselves unwelcome in Germany during the 1930s, and one of the two reasons was that all of them were Communists. They moved to the USA, settling down in Columbia University. How did they repay the country that gave them refuge? By subverting it, of course. If all this sounds like McCarthyist alarmism, note that the Communists themselves claim them.
