I agree absolutely. Saddam Hussein should have done that. I intend to show why he would never do it.
Would the people of Iraq be better off if Saddam Hussein were dead or in exile? The answer is undoubtedly yes. Does the Iraqi regime have weapons of mass destruction? It almost certainly does. They are possibly so well hidden that they would be difficult to use immediately. Has Saddam Hussein supported terrorist organisations? Again, the answer is yes, but, as far as I am aware, to a lesser extent than Syria. None of those factors justifies immediate military action.
Much more could and should have been done to bring irresistible pressure to bear on Saddam Hussein by, for example, extending the no-fly zones to cover the whole of Iraq, by requiring Iraqi military personnel and equipment to be returned to agreed positions or by demanding that the weapons inspectors had unfettered access to sites and Iraqi personnel. Such draconian measures might have received international approval, and might reluctantly have been accepted by Saddam Hussein, provided that the visible threat of war continued. They certainly would have degraded the Iraqi regime's ability to resist military action if it came. Obviously, I cannot prove that my ideas, or any others, would have worked. I believe, however, that much more could have been done, and that much more should have been done differently, so that the effect of prevarication or cheating would have been obvious. We did not do that, however. Instead, we made demands that the Iraqi regime was always unlikely to accept, and which, if it did pretend to accept them, would be easy to cheat or lie about, as its dishonesty was hard to prove.
So, we are faced with war. It is a war whose justification will not be accepted by most of the Muslim world. Too little fresh thinking has been employed in trying to avert it, and its rationale has changed as each reason has remained unproven. It is portrayed as a war of last resort, yet it appears to be born of frustration with a regime and a leader without whom the world would be better off. I will give my unswerving support to those whom we have sent to fight in our name, but I will not support a premature decision to wage war. I hope that we will not come to regret this, but I fear that we will.
