"But watching those kids cheering for Ho Chi Minh's China and Mao, and spitting on the American flag, I wondered: what do they know about China? And do they know what communism, which they like so much, is? I had been to Poland in 1956 and to Czechoslovakia the following year. I would have liked to take those students on a trip there to show them up close what they were peddling as the dictatorship of the proletariat."
