I’ll kind-of bite.
I believe that Saddam might have some light-weight chemical weapons, maybe some plans for some nukes. Maybe a bit of research going on with biological weapons.
But I don’t believe that Saddam has a working nuclear weapon, nor any chemicle or biological weapons in a state to do any actual mass destructions.
Saddam has nothing to gain by using WMD. He is interested primarily in maintaining his own power. Unlike a religious fundamentalist, Saddam has plenty to lose. Thus we can expect him not to act in ways that would lead to his immediate destructions.
The big scenerio being thrown around is “Saddam nukes New York”. Of course, he has no way of getting a nuke to New York, but we can ignore that for now. Saddam would gain nothing from nuking New York. He is in no position to maintain a military occupation of America. He is not in position to replace America’s government with one more friendly to his purposes. All he would acheive is his immediate destruction. I think we can rule this plot out.
Israel is somewhat of a target for him. Striking Israel would certainly buy him some respect in the Arab world. But short of obligatory anti-semitic rhetoric (which is a bad thing, but not unusual for the area), Saddam doesn’t really have all that much against Israel. Striking Israel would plunge his entire region into war, and with that war would come religious fundamentalism.
And Saddam is not a big fan of religious fundamentalism. He runs a pretty secular state, and an upsurge of religion in his country could only end with him out of power. He wants to avoid that.
So who is he gonna use this nuke on? All I can think of is Iran. But remember, if he uses it on an Islamic country, he will become a bad guy in the eyes of the countries that surround him- leading to the end of his power. Not a good thing for him.
If you have nothing to nuke, why build a nuke. He doesn’t even have a reasonable target to threaten if he wanted to use it as extortion. I don’t think he has one.
He certainly has some amount of chemicle weapons, but no real biological weapons. Mostly he’d want to use these in his own small-scale wars. He has nothing to gain by starting a wide-scale smallpox epidemic. Although henious, I don’t believe that chemical/biological weapons that are not a threat to more than a limited number of people (say, on a battlefield) count as WMD.
