It'll be a military occupation, that is the only way to make sure that the old rulers don't try to take back the country. If you look at most countries that deposed bad rulers, you would quickly realise that they just got rid of the figure head. The economic and political regime still remains and the high-level bueracrates from the previous government just take over the new one, usually on the pretense that have experience needed to control the resulting devistation after a internal war.
A democracy is a very fragile thing in the beginning. The old rulers still have a lot of control and most people fear them, and agressive opurtunistic leaders seek personal power from the caos of a social transition. That's why you need the military occupation to set limits on what happens and how quickly different people gain power.
The UN basicly trashes every thing it touches, I doubt it hasn't had a successfull campain to make positive changes in any conflict. It mearly drags on and on year after year after year, because the more situations that the UN controls and is involved in the more powerful it becomes. To actually solve problems would be counterproductive. The US on the otherhand can only benifit from other people being free, mostly from a economic standpoint, but also from a social one. Once you are able to trade and travel freely between 2 countries it benifites the people from both countries much more than a continual expensive military conquest in which one side dominates the sociaty of the other ones. If the US took that track then we wouldn't be were we are today. It's impossible for a Empire to self-sustaning, that's why Great Britian, France and Germany are just european nations and not world powers like they were at one point in time. The US has learned from the mistakes of the Europeans.
Japan and Germany (and France in a lesser way) are 2 major examples of what can happen when we are able to establish peace in a region thru dominate military force, that is the only way sometimes, unfortuantly. We did not set up puppet governments in France and Germany like the nazis and the communists/socialists did. We could of continued to run Japan and turn into a second Hawaii, but we didn't. And I don't want to hear on how the middle easterners are not Germans or Japanese and are not capable of living side by side because of the tribal mentality. That viewpoint is actually realy racsist if you think about it. You are jsut assuming that europeans have some sort of generic intellectual and moral superiority over the brown races of the planet.
And do you think that George Bush after working this hard and putting his military forces thru this strain is going to allow a orginization that has Libya of the leader of the human rights council to control another middle eastern nation, your freking nuts.

Also I am sure that Europeans have a much more pure "democracy" than the US, because it's just SO obvoius that they don't elect leaders to represent their viewpoints like us heathens in this Representative Republic, but they hold referendums on every law and statute that gets passed and every European votes on everyting like in a "pure" democracy.. the majority rules constantly, eh? (/sarcasm)
