>> One thing is certain - this war is nothing like the situation post-WWII in Japan or Germany or Italy and it is not reasonable to apply that model to this situation.

>I am not sure if this situation is different than Japan and Germany. What makes you think it is different?

1) There was no U.N. back then;
2) There was no international setup for the distribution of humanitarian aid back then;
3) WWII was a very lengthy war with virtually all infrastructure destroyed in Japan and Germany;
4) The people of Iraq will be grateful (as opposed to belligerent);
5) Iraq has natural resources of high value to allow it to rebuild/grow on its own. Neither Japan nor Germany had such opportunity.
6) The economy of the world operates differently now. Businesses can now do what only government could do back then.

Those are some major reasons.
