Well, yes. OTOH, I've noticed over the past few months that the term "neo-con," especially, has started popping up a lot, and that it's usually tossed out there by those with an isolationist and/or anti-Bush point of view.
Indeed, I've found it to be an excellent indicator for a whole set of common views expressed by what JimRob has neatly summarized as the paleocon/paleolibertarian/buchananite/rockwellian/anarchist/Democrat/French/German/Iraq axis.
