Think of the term "neocon" as a vessel into which True Conservatives™ pour all of their frustrations, imagined or not.
As an experiment, try to get them to define it--you'll get a hundred different answers.
And usually it will all lead back to one thing......'The Joooooooos.'
Don't ask me to define it. Can't do it.
That’s not true. The late IK said
“QUOTE: ‘Ever since I can remember, I’ve been a neo-something: a neo-Marxist, a neo-Trotskyist, a neo-liberal, a neo-conservative; in religion a neo-orthodox even while I was a neo-Trotskyist and a neo-Marxist. I’m going to end up a neo-that’s all, neo dash nothing.’”
And Ron Paul is very explicit and precise in his prescient 2003 critique of neoconservatism:

It used to be that “neocon” was a term only used by the rabid anti-semetic left.
More recently it has been embraced by the anti-semetic right, few as they may be, namely Pat Buchanan and Ron Paul supporters.
Almost forgot.
Thoughts are with William Kristol and his family.
