Crowing
If you look at who's doing the crowing, it's the NO WMD'S FOUND! crowd. My own view is that while I'm a bit puzzled that nothing solid has turned up yet, I'm not that concerned this early in the game. I'm willing to wait a while before jumping to one conclusion or the other.
We should also not ignore the circumstantial evidence either.
Feel free to move this discussion to one of the more recent NO WMD'S FOUND! threads, since Don starts a new one about every four hours.
