Hussien has proved over and over to the world that he is an unstable element in the middle east, and someone, somewhere is going to have to deal with him. Since he kicked the U.N. mandated weapons inspectors out, four or five years ago, no one knows how his weapons development/ aqquistion program is going. He still has some 400k men in the army, of which 100 thousand are the Republican Guard, (which by many are still considered seasoned, well trained, well disciplined troops). Given time, he will find a way to drop a WMD on Israel. Do we remove him from power now, or do we wait and let the Israelis retaliate for the attack that will come. That could bring Armaggedon to the Middle East.
Offering a hand to a rabid dog could very well result in a dogbite.

Can we defeat him without a war? While much more pleasant, I'm doubtful that it will work. Ten years of sanctions have done little to affect change in the Iraqi leadership.
Can we, meaning the civilized nations of the world talk him down? Possibly, but for how long? And talking him down gives him more time to work on his NBC devices. I really don't see any way to oust him other than by force. I'd rather not see that happen. But I really don't want to see Iraq use WMDs on Israel, or Israel respond with a nuke of their own.
It's a violatile situation, and will have to be addressed sometime.
As far as either Nader or Gore goes, the initial response to the actions of Sep 11 would have been virtually the same. How things would have progressed from there is speculation.
