Why not admit they were wrong?
1. Saddam was found how long after the war, and how? On a tip. If that person hadn't spoken to the right people, we might never have found him. And he was practically in plain sight.
2. SH was behaving as if he had weapons. Now you might say it was all a bluff, but there is a good chance he wasn't.
3. How will history view us if we go away without a good hard look and it's later found they were right there all along.
4. No one expected it all to be laying right out there on the sand dunes. It was always going to be a hard job.
Now it's real easy to believe that nothing existed prior to the war, especially if that's what you want to believe, but we are there, and we'd better be sure. If the worst that can be said is our intelligence was wrong, that's something to work on, but in the end SH was bucking UN mandates and was fairly well asking for a resumption of hostilities. That was stated as often as any reason to go to war against Iraq, despite the idiotic protestations of political partisans to the contrary. My gosh, it's a matter of public record, google it. You would have thought it was years ago and not this past spring.
