Ours will neither be a perfect world, nor a world without disagreement and occasional violence. But it will be a world where the overwhelming majority of national leaders will consistently abide by the rule of world law, and those who won't will be dealt with effectively and with due process by the structures of that same world law. We will never have a city without crime, but we would never want to live in a city that had no system of law to deal with the criminals who will always be with us.
