This administration is not keen on admitting that it was wrong, and even though they take advantage of the occasional fall guy (like blaming the intelligence failures on the rest of the world), they would much prefer to come up with other plausible, even if unprovable, explanations that would in some way vindicate them entirely.
So I would expect that sometime between now and September we will hear a story about how we have "proof" that the WMD's are in Syria, Iran, or somewhere else. Satellite imagery will be leaked to the press that shows trucks rolling across a border or some big holes in the ground somewhere. Now, these pictures won't show WMD's but they will allow the Administration to say "These trucks were dumping WMD's in those holes," with no real way to refute it. Without invading, the target country (be it Syria, Iran, NK, etc) we will have no way of saying that this didn't actually happen, but will allow Bush to give his on-the-fence supporters something to latch onto.
The only thing better than that would be for Bush to find a way to be able to implicate the U.N., France or Hans Blix in the process. By doing so, he could not only toss out an explanation to the WMD's, but also cast doubt on those who stood against him.
And if this does happen, my questions are going to be, "where have those pictures been for the past year, and when are we invading Syria (or wherever we are going to say the WMD's are)?" They will of course say that we can't invade right now and that we will take other measures to control the WMD's. Of course, then my question will be, "When did we come up with other measures for controlling WMD'S? I thought we invaded Iraq because that was the only option???"
I may be wrong, and I'm taking a sizable risk by tossing this prediction out there, but I'm feeling pretty good about it. And why would now be the first time I've ever been wrong. Play the odds people, go with me on this one. But if you don't agree, be sure to reply now so that I can know who I need to laugh at when I'm shown to be correct.
