At Rolling Stone, Matt Taibbi has noted a huge split amount conservatives. Not all of them want to be seen as hawks anymore:

It’s been interesting, watching the seamless transition many conservatives seem to be making now, from brainless war-drum-beating to Randian isolationism. Six or seven or eight years ago, I seem to remember, anyone who even hinted that not using military force to resolve any foreign policy dispute, no matter how trivial or how imaginary the justification, was to be considered a traitor.
