Hans Blix is curious and so is everyone else. The ex-inspector seems to think that even if Iraq does have chemical or biological weapons, they won't be used against coalition forces because "people would say, 'So, they were liars. They lied about this and there was a justification for the intervention.'" Somehow, I'm not sure that Saddam is too worried about people thinking he's a liar, when people already know he's a brutal murderer.
Still, it does surprise me that our forces haven't announced any significant WMD finds. I suspect that it's largely because they aren't looking that hard yet; there are more important things to be doing at the moment. This WaPo/ABC poll indicates that "More than two-thirds of those interviewed-69 percent-now say that the war was justified even if the United States fails to turn up biological or chemical weapons, up from 53 percent in a survey taken the day after the war started." That's pretty much how I feel, as well... but I would still like us to find something. I've been very confident in the past that Saddam has had such things, but the lack of hard evidence (that we've been shown so far, anyway) at least gives me pause.
