Matt Yglesias makes a point that's bugged me for a long time too:
Nobody takes the views of someone who’s a pacifist in general seriously on a specific question of war and peace. But if you’re Bill Kristol, and every time an issue comes up your idea is that we should launch a war, then you get to [be] a Washington Post columnist and a constant TV presence. Here he is with Brit Hume calling for “targeted air strikes” against North Korean missiles:
Why is this kind of stuff taken seriously? Everyone knows perfectly well why we haven't launched any kind of attack on North Korea: they have lots of troops and lots of missiles and could destroy Seoul and kill millions of people if they decided to. Kristol knows this perfectly well. But his endless knee jerk talk of military force as the answer to all problems is given a respectful hearing anyway. Can't we just put a stuffed doll with a tape recording in his chair instead? It would save Fox some money and the analysis would be the same.
