1. Sadam is a wild card.
Sadam is a wild-card and would co-operate with Al-Queda if he had a chance (may have already done so according to US) along with causing other chaos in the middle east; just look at what he did back in 1991.
Looking forward it makes sense to remove him now while there are no other issues on the table.
2. Weapon development/caches.
Based on UN 99 reports (which are probably tip of the iceberg) there are many stores of un-accounted items. What is the likely hood that UN inspectors will find hidden caches of arms? Bottom line is you cannot trust a rogue nation like Iraq to willfully disarm imho. Searching for arms is like literally searching for a needle in a haystack.
Also interestingly I had an Iraqi taxi driver the other week (Toronto) and posed the question to him. He quickly replied that the sooner Sadam is gone the better it will be for his relatives there. The war may be about economic/political control but also in the end hope that these people will have a better lifestyle
