I have been reading up on the just war doctrine, specifically the vatican's response to iraq. Based on numerous articles such as this one: Catholic Just War Theory and Iraq it is clear that the vatican was against the war. where does this leave usa soldiers who are going to iraq to fight? I would think that once they are there, any killing on the field who fall under self defense, but what about pre-deployment? From what I know, jesus said that you follow your govs rules as long as they don't break his. Seeing how catholics believe that the pope is infallible (one to one with god on things he says related to the church), aren't catholic soliders out of line with their church if they deploy to iraq knowing they will be killing. should they take the religious objector way out?
