The analogy with Post-war Germany and Japan is a false one. We didn't attack them in order to introduce democracy. They attacked us and were soundly defeated. We then treated them generously [The Marshall Plan] - not the way we treated Germany after the First World War - and they responded positively. They became true democracies and faithful allies of the United States. It took President Bush's policies to upset the Germans. As you know, German Chancellor Schroder managed to stay in power by taking an anti-American platform. This goes to show how much damage Bush has done to America's standing in the world.
I'm all in favor of removing tyrants like Saddam but the way we went about it has made it more, rather than less difficult, to do it in the future, because we acted unilaterally and arbitrarily. How to protect the world against the likes of Saddam is the great unresolved problem of the present world order. We certainly cannot do it on our own.
