Of course, the doctrine of pre-emption is incompatible with official Roman Catholic as well as classical teaching on just war theory. The doctrine of pre-emption does open the door to other states making the same sorts of claims whether they are factual or not.

Just war theory? Roman Catholic teaching? The United States of America must defend herself when it is required and before the threat is imminent.

If tyrannical/terrorist regimes such as Iran or Syria or North Korea try to do pre-emptive wars then they must be destroyed pre-emptively by the United States.
