Look's like I've said one of those "true if you think it's a good thing, crazy conspiracy if you thank it's a bad thing" facts. No one really denies the link between Jewish Americans, the various Jewish organizations that are active in politics (AIPAC, ADL etc) and US Foreign policy. But people strongly deny this in the context where people criticize foreign policy, and want to redirect discussion towards safe topics like the military industrial complex or oil.

Some will say the most American Jews are liberals and therefore wouldn't support neoconservatism. It's true that they are mostly liberals on domestic policy, but by judging candidates on a single issue (Israel) they end up implicitly helping neoconservative thinking, which places the most emphasis in the US-Israel relation.
