Not sure how you mean that. The Neocons have defined themselves, as in my article on the subject--and as others have also described in this thread. They are definitely on the Left--see, again, The 'Neocon' Phenomenon, but I do not think it fair to describe them as "anti-semitic." While the more prominent "Neocons" have been associated with the Bush policy in the Near East, calling them "anti-semitic" is a bit of a stretch. Would you call partisans of the IRA, "anti-Celtic?" Conversely, would you call Ian Paisleys' followers, "anti-Celtic?"
Anti-Semitism has nothing to do with either side to this argument, and it is somewhat demogogic to suggest that it has. The issue is about what the "Neo-cons" believe. Is is supportable, rationally? No. Is it Conservative? No. Is it new? No. It really wasn't new in 1917, although that was the year it came into vogue with some mean spirited folks.
