"Harry Wu," Mr. Buckley begins, "is in a serious sense to be compared with Aleksandr Solzhenitsyn." As a young man he had criticized Communism during the short-lived Hundred Flowers Campaign, for which offense he was sent to Laogai (the Chinese equivalent of Gulag); as the winds of change blew through China in 1979, following Mao's death, he was released and was allowed to emigrate to the United States. In 1995 he was arrested trying to re-enter China in order to document his assertions about Laogai. This time he was expelled from the country instead of being sent back to the camps where he had spent 19 years. His English is somewhat halting, but his mere presence is a tremendous witness to the human spirit, and he gives trenchant advice about how the United States can help the cause of freedom: "China today is on a crossroads of the history. This is very good opportunity for Chinese and American and the people of the world. Give a little bit of push and the Communist regime will disappear from China. ... You mentioned a student personal exchange. Very good program. Radio Free Asia: very good program. But you know, Chinese did not accept the reporters from Radio Free Asia, denied their visas. If America says, 'If you deny their visas I will deny your visa and I will cancel some of the economic contracts,' that is some real thing in the constructive-engagement policy."
