Jim Henley goes deeper into the foibles of the liberal hawks:
Now a lot of the disenchanted liberal hawks I know complain less about brutality than about mismanagement. In this they take their lead from the Kerry campaign, which has focused its criticism on the Bush administration’s incompetence and “failure to win the peace.” Complain that Bush committed “too few troops to secure the peace” and you can, for possibly enough listeners to get you elected, attack the incumbent without sounding “soft.”…
We invaded Iraq with the force we did because it was the only politically viable way to have the war at all. Until well along the buildup phase when the familiar “close ranks” phenomenon hit the American public, support for immediate military action against Saddam Hussein’s Iraq was tepid. The Bush Administration’s political people knew perfectly well that a bigger, more disruptive deployment and less cakewalk talk risked sinking the whole deal. To say “We shouldn’t have invaded Iraq with such a small force” is to say “We shouldn’t have invaded Iraq.” It’s just not saying it forthrightly.

For what it’s worth, I think the liberal hawks were somewhat naïve in thinking they could have the kind of war they wanted on their terms. “Liberation” always seemed, at best, a secondary consideration in the administration’s public case for war. And any war for liberation, if such things are to be undertaken, has to be judged by its prospects for success, not just the good intentions that may lie behind it.
