It was to the UN that those cease fire promises were made and it was the UN that was dealing with Saddam. The Security Council had the responsibility to use force to enforce those provisions. They wisely decided against that course of action.
No, the cease fire was negotiated by Schwarzkopf and signed by the leaders of the coatlition. It was up to the coalition to patrol the no-fly zones and it was they who were fired upon, negating the cease-fire.
You seem to have a real love for the UN, when they have constantly proven themselves to be worthless. Face it, as has been shown, Russia, France and Germany had too much to lose to allow war in Iraq to happen. They didn't give a rats ass about our security. You may want to surrender our sovreignity to the UN, but I don't.
