The point of the "sanctions" was containment. But the sanctions were a joke. Saddam was using this money he made to bribe UNSC members to get the sanctions dropped so he could continue seeking weapons of mass destruction. He was harboring terrorists. He was breaking his cease-fire agreements. He was destroying his own people. He was a threat to our allies in the area, he was a threat in his support of terrorists, and if you don't agree, that's your view point, but you disagree with most of the national leaders from both parties at the time. If you'd like to disagree because of hindsight and perfect knowledge, that's nifty but not realistic. The bottom line: his removal is a net good.
