IIRC, we’ve had this debate before. Personally, i think that your contention is ridiculous.
Certainly it’s true that a noticeable percentage of influential people who can reasonably be desribed as neo-cons are also Jews, but it takes much more than this to demonstrate that “neo-con” is some sort of anti-Jewish slur, which is what your OP seems to be suggesting.
Even the term neo-con itself has changed over time. It is now, as you suggest, quite closely associated with Leo Strauss and those in power who subscribe to his theories and ideas. But the earlier definition of neo-con related more closely to people who had originally been Communists or communist sympathizers, but who shifted away from communism and become, in fact, vocal opponents of communism and boosters of Americanism. Admittedly, quite a few of them were Jewish, but there have also been a considerable number of people described as “neo-cons” who are not Jewish.
I’m not discounting the possibility that some people use the term neo-con as a derogatory synonym for Jew. For the most part, however, a neo-con is a person who subscribes to a reasonably well-defined political ideology or world-view. Whether that person is Jewish or not is, for me and for most political commmentators, really quite beside the point.
You mention in your OP that discussion of the neo-conservative view often includes mention of Israel. Well, considering that one of the places in which neo-cons currently hold most influence is in the area of US foreign relations, surely Israel is going to come up quite frequently. Whether you’re a neo-con or not, it’s hard to talk about US foreign policy for very long without getting on to the subject of Israel, especially given the current importance of the Middle East in world affairs, and Israel’s role as a key US ally in the region.
I get the impression from your OP that you’re talking about those who criticize both neo-conservatives, and who also criticize Israeli policies. I’ve heard this connnection made before, and often in the same sort of context that you are raising. The implication is often that those who oppose Israeli foreign policy, and who oppose neo-cons, do so out of anti-Semitism. IF you are making such a suggestion (and i’m not saying you are), i just want to point out that, despite the tendency of some people to conflate the two, opposition to Israeli foreign policy IS NOT the same as anti-semitism.
