"I'm not saying the Iraqis won't use them. But shouldn't they have done it by now?

I mean, if they were all that eager.

Shouldn't al-Qaeda or someone used them in Israel or the US, by now?

If Saddam is going to get those into the hands if terrorists, why not by now?"

That's a problem with some dogs: excessive drooling. That, and their tendency to be preoccupied with licking themselves.

If the Coalition forces had found WMD, there is no need to publicly disclose this at this time. The people protesting the war don't care if Iraq has WMD, or even that Saddam would like nothing better than to use WMD on the very streets they are marching on.
The people who are supporting our troops, know why there is no advantage to publicly disclosing evidence of Saddam's WMD at this time.
