Possible, but I don't see that happening.
Iraq doesn't do the suicide bomber scene. That's a Saudi and Palestinian thing.
To put it another way, there is the same chance that an Iraqi suicide bomber will carry a nuke to the US as there is that a Chinese suicide bomber will carry a nuke to the US. Just as no Russian suicide bombers carried nukes to the US during the cold war.
The same with the chemical/biological attacks.
If he did develop them, we would not be his first target. Just as he didn't fire a bunch of SCUD's with chemicals on Israel during Gulf War I. But he will use chemicals against the Kurds.
