It's very likely we'd have had war. If airstrikes were used, Clinton would go for Saddam himself as revenge. (He defeated Bush, but was more than willing to continue many Bush policies.)
If Saddam was killed, I'm not sure who would succeed him. His sons might, or Hussein Kamil might step in. It's also likely that the Kurds (who were uinder US protection) and the Shi'ites in the South might take advantage of this and try to revolt.
I think that Hussein Kamil had the WMD destroyed by then, but if someone else took over, things might be revived, or the scientists might pull an A.Q. Khan.
