Wow. I stumbled onto a site with waaaaaaay more information than I care to read about Iraq's maybe/maybe not status as a Just War in the Catholic tradition. Having served my time in the Gulf, I've had about as much of the subject as I care to. The name of the site? Why, The Catholic Just War Tradition and the War in Iraq, of course! Since it's brought to you by the Ratzinger Fan Club, you know it's good.
While they apparently only have one MP3 on the topic ("The War Against Terrorism", Remarks by George Weigel and Bill Kristol), they have a ton of other materials, from statements by then-Cardinal Ratzinger to Archbishop Martino and Michael Novak. If this is your thing, this is definitely your site.
