Fanny, I suggest that you do your best to stop projecting your concepts of what was, what is, and what should be onto others.

Hans Blix and the inspectors were not permitted to visit certain sites, remember? The then-Iraqi government became more and more uncooperative, even to the point of refusing to allow the UN to service the monitoring cameras.

The Korean Police Action ended with a truce, which is still in effect, not a rout as the Vietnam Conflict did. (They were NOT wars as they were not declared. Neither is this one. This is not to say that they may not have been unconstitutional. As a former infantryman, I tend to think that any time someone is trying to kill you you're at war, constitutionality be hanged -- but that's a very personal definition.)
