Not true. Neocons are defined not by religion or race but by IDEOLOGY.
For example Michael Savage and Noam Chomsky are Jewish, would you classify them as neocons?
And would you classify Daniel Patrick Moynihan, Condoleezza Rice, Donald Rumsfeld or Richard John Neuhaus as Jewish?
How do you label Rumsfeld and Moynahan as neo-cons? Rumsfeld was never a liberal, and Moynahan was never conservative, always a liberal -- just a clear-sighted one.
I did mention an ideology, or at least the principle that underlies it. I note that while the term neocon seems usually to be identified with those who are Jewish, it doesn't make all Jews neocons, though I think there is a tendency to tar all Jews with the sobriquet.
Rice and Rumsfield come very close to being neocons in my view, as does the President himself. Perhaps only the Jewish identity is missing on their part.
Maybe a better definition is someone who is a hawk on foreign policy. Someone who believes America is a force for good in the world.

No. I'd classify them both as a waste of DNA. Expect that (his politics aside, which I find simplistic to say the least) Chomsky can claim to have actually done something.
