Right, and also Bush would be blamed for not getting them before they were shipped off to Syria, and every day since for the fact that they're still there, or who knows where, held by who knows whom, who will do who knows what with them - his political critics would have a field day.
At this point it's probably much better for national security purposes if the whole world (including Syria - I think they ARE there, btw) believes that we think they never actually existed. Bush takes a hit, but like a previous poster pointed out, he's more concerned about security than poll numbers. I think we'll get them eventually.
From your lips to God's ears...
