A lot of people would question that, and not just "isolationist, non-interventionist paleos."
They made some really serious miscalculations that hurt the country.
One reason not to get so enthusiastic about Palin is that, like Bush, she'd simply defer to the neocons on foreign policy.
Maybe if they really irritate her (and "they" is a confusing term here since the people who write about foreign policy and those who deal with domestic policy and social issues aren't the same people), that won't happen, but I wouldn't count on it.
“Neocon” means a lot of things. On foreign policy it has come to mean pro-Israel, anti-Cremlin, anti-terrorist, pro-freedom (in the sense of aiding opponents of our enemies) and if needed unilateral US action.
This is also where Palin stands. One could also call it common sense, strong US foreign and defense policy.
Domestically the “Neocons” are indeed Democrat-lite RINOs ala Giuliani, Romney, Frum etc.
This of course is were she stands opposed to it.
