The concept of a just war
A lot of what Chris talks about two or three articles down discusses the fact that America had a higher purpose in invading Iraq, that of saving the Iraqi people from the slaughter of the Baath party. While such a slaughter has occurred, the policy, at least to me, remains troubling on moral grounds and the precedent it sets.
Take a look here and follow some of the links at the bottom. They go through the argument of the just war pretty well, decidedly better than I can do.
So if your neighbour was beating his wife, crippling her, injuring the children, you wouldn’t do anything?
Would I go in to a house where the wife hates me for some help I gave one of her enemies, beat up the neighbor, run him into the basement, then attempt to run the house as my own, taking some of the cash out of the cookie jar along the way?
This situation can’t be boiled down to simple analogies.
