Categorically, absolutely, 100 percent a slander. Zinni served as Bush’s personal envoy to the Middle East in 2001 and 2002. One can argue whether Zinni is pro-Israeli enough for the Administration’s tastes, but the baseless charges of Zinni being an anti-semite is as outrageous as arguing that the State Department is a threat to national security, and that it ought to be nuked.
Oh, wait, the author of that column DID write such a book! “Dangerous Diplomacy: How the State Department Threatens America’s Security.”
Anyway, in reference to the OP, Zinni’s comments did get quite a bit of play. He was interviewed by 60 Minutes and several other respected news programs. BUt the media doesn’t tend to dwell on a particular bit of news for too long. Otherwise, there’d probably still be front-page stories about Bill Clinton’s book during the slow August news season.
