A doctrine of illegal, "preemptive" war undermines the international order established after World War II, and it must be rejected. A Middle East free of weapons of mass destruction is a necessary and worthy goal, but it should be achieved through a process of negotiations and inspections, backed by an international treaty.
Regime change, when it occurs, should be the result of a free and democratic internal process, not imposed by force from outside. Our region needs a strong UN and relations between countries and peoples based upon the rule of law.
War and violence are not the means for resolving conflicts.
