I think the 'war-radicals' describes them a bit better than 'neo-cons'.
For a 'pure-blood' conservative (as opposed to those in the USA who used 'conservative as a cover or anti-Black White Supremacy), spending blood and treasure in an aggressive action is ALWAYS anethema. Conservatives were isolationists. Unlike the Rumsfeld-Feith-Bush-Cheney-'war is the solution to all problems' crowd, a conservative, a true blue, dyed-in-the-wool, Barry Goldwater conservative, would hae rejected both the Bush domestic and foreign policies.

Not blind. Not uninformed. We are party to atrocities. But the response of the world after 9/11 is worth noting. Even our most dire enemies offered aid. We should all be so lucky.
