Cold War Porn.
The French have an expression, "drowning the fish," meaning you overwhelm your opponent with data in order to avoid actually answering his point. The Dancer Defects is meant to counter Frances Stonor Saunders's devastating "The Cultural Cold War," published in the UK as "Who Paid the Piper."
Unfortunately, Caute is of that breed of intellectuals whose political stance consists in being neither Right nor Left, but merely standing to the right of the Left and the left of the Right: he counters Saunders by accumulating factoids (fascinating factoids, I'll admit) that are meant to prove that either side in the Cold War was reaching for the lowest common denominator in their rush to use Culture for their own ends. His methodology is that not uncommon subgenre of historical research, the light-scholarly book that relies almost exclusively on press clippings. His stance: "Of course, Communists eat babies; on the other hand, MacCarthyism was bad, because some non-Communists were caught in the net." That there might have been a large number of writers, musicians, dancers, etc., that were caught between the two superpowers, is something Caute doesn't really consider, and that's unfortunate, since that was Saunders' most devastating point.
I'd give Caute an extra star for the factoids (728 pages, including notes), except that after following up on a few footnotes I found that he frequently misquoted or misunderstood his sources. This is not a book, it's a poorly annotated bibliography.
