I am not an expert on Brzezinski, and this is not an apology for him. He was a Cold Warrior, as essentially was everyone in Washington during the Soviet era.
For 12 years Brzezinski was my collague at the Center for Strategic and International Studies, where I occupied the William E. Simon Chair in Political Economy. When I was elected to that chair, CSIS was a part of Georgetown University. However, the president of Georgetown Univerity was one of those liberals who hated Henry Kissinger, who was also our colleague, and the university president also hated Ronald Reagan for his rhetoric, not for his deeds about which the Georgetown president was uninformed. So I also was unwelcome. Whatever I was worth to CSIS, Kissinger was worth more, and CSIS was not going to give up Henry Kissinger.
Therefore the strategic research institute split from Georgetown university. Brzezinski stayed with CSIS.
When my 1971 book, Alienation and the Soviet Economy, which had circulated clandestinely inside the Economic Institute of the Soviet Academy of Sciences in mimeographed form for years, was republished in 1990 with an introduction by University of California, Berkeley, Professor Aaron Wildavsky, Brzezinski, along with Robert Conquest and two members of the USSR Academy of Sciences, provided cover endorsements for my book.
