It’s not “clear” at all that it was an unjust war. St. Thomas Aquinas’ criteria can be stated as follows:
- Last Resort
A just war can only be waged after all peaceful options are considered. The use of force can only be used as a last resort.
Some may argue that not all peaceful options had been exhausted. Certainly, Saddam’s last one was to go to protected exile. Never did he stop violating the cease fire agreement. Never did he stop paying for the assassination of Israeli civilians.
- Legitimate Authority
A just war is waged by a legitimate authority. A war cannot be waged by individuals or groups that do not constitute the legitimate government.
Speaks for itself. The executive and legislative branches approved it.
- Just Cause
A just war needs to be in response to a wrong suffered. Self-defense against an attack always constitutes a just war; however, the war needs to be fought with the objective to correct the inflicted wound.
I think this is where the argument actually is the most difficult for many. The “wrong suffered” does not have to be one’s own nation. Saddam started two aggressive wars and killed a million people. There was no reason at all to imagine that he would never again do that kind of thing. During the cease fire, he murdered more civilians and paid people to assassinate Israeli civilians.
- Probability of Success
In order for a war to be just, there must be a rational possibility of success. A nation cannot enter into a war with a hopeless cause.
It did succeed.
- Right Intention
The pirmary objective of a just war is to re-establish peace. In particular, the peace after the war should excede the peace that would have succeeded without the use of force. The aim of the use of force must be justice.
Bush and the congressmen knew what their subjective intentions were. At a point, the war produced a peace that all three factions found satisfactory enough to ask the U.S. to stay.
- Proportionality
The violence in a just war must be proportional to the casualties suffered. The nations involved in the war must avoid disproportionate military action and only use the amount of force absolutely necessary.
The allies took great pains to avoid excessive causalities. The nature of the “end run” strategies instead of brutal frontal assaults evidenced a desire to minimize casualties.
- Civilian Casualties
The use of force must distinguish between the militia and civilians. Innocent citizens must never be the target of war; soldiers should always avoid killing civilians. The deaths of civilians are only justified when they are unaviodable victims of a military attack on a strategic target.
I don’t think any sane person seriously argues that noncombatant civilians were specifically targeted.
Yes, I know. Counter arguments can be made, and some have made them. But my point is not that we should restart that debate here. Rather, my point is that it is not “clear” that the Iraq War Phase II (it never actually ended from Phase I) was “unjust”.
