No war is “good” in an absolute sense. People always die in a war. That’s the nature of it. Any war must be measured against the alternatives. It is indeed unfortunate that this country abandoned the allies it had gained in Iraq and thus threw away the sacrifice of the troops so Obama could say he ended the war his minions had made unpopular by incessant propaganda aimed at persuading people that Iraq was the “bad” war and Afghanistan the “good” war.
I realize there are absolute pacifists in this world. They are entitled to believe as they do. But if one is not a pacifist, (and the Church does not require pacifism of us) one needs to consider which evils are properly to be opposed or ended.
As the killer of a million people, torturer of thousands, the starter of two wars and user of WMD both in war and against his own people, as well as a breaker of the truce, Saddam Hussein was surely a sufficiently evil force to oppose.
If not him, then what evils in the world do you think are worth opposing?
