To prosper in the long run, the GOP needs to wean itself off its addiction to neocon money and media influence, which has been so disastrous in foreign policy. But that's hard to do because of, well, neocon money and media influence. (E.g., Krauthammer and Kristol get fired as columnists at Time, but Kristol pops up instantly at the NY Times).

It will be doubly hard for the GOP to wean itself off the neocons because anybody who points out the mere fact of neocon money and media influence is denounced as an anti-Semite. And most people in public life would rather let America blunder into more Middle Eastern wars than be denounced as anti-Semites.

Of course, neocon/neolib loyalty to the GOP is a lot less of a sure thing—they are maneuvering to try to dominate the foreign policy of the next Democratic administration.
