If the UN is to have any beneficial role in the future of the world, the Security Council must live up to its responsibilities from now on. That means it must never again behave as it did during the Iraq crisis.
What, then, is to be done about France? Here's a possibility. France can retain its permanent membership of the Security Council, but with a slight alteration in the voting rules: any vote cast by France must have the unanimous consent of all other EU members. Without such consent, France/EU is deemed to abstain.
This at a stroke would make the UN more effective, increase the EU's role in world affairs, encourage European unity and promote multilateralism. Since these are all prime aims of French foreign policy, France would welcome the change.
Heh heh heh.
