George Schultz has a much more detailed litany of Iraq's wrongdoing than I gave yesterday. The only thing necessary for those who doubt whether this amounts to a just cause is to trust Thomas Aquinas. Why is this so hard to understand?

Secondly, a just cause is required, namely that those who are attacked, should be attacked because they deserve it on account of some fault. Wherefore Augustine says (QQ. in Hept., qu. x, super Jos.): "A just war is wont to be described as one that avenges wrongs, when a nation or state has to be punished, for refusing to make amends for the wrongs inflicted by its subjects, or to restore what it has seized unjustly." Summa Theologica, Q. 40.
