We acted in Asia's and Europe's interests during WWI and WWII, lost 500K dead and spent 2x GDP fighting those wars. I don't recall anyone giving us money for those wars, which were fought at much greater expense in men and money. I think we mistook the Iraqis for the Kuwaiti and Saudi Royal Families. They did not have to hand us the cash, but they did so anyway. Iraqi Justice shows us that not all Arabs think alike. Ordinary Arabs hate our guts and have a record of assassinating or deposing and executing rulers who seem to be too close to Uncle Sam. Their rulers are much more moderate (and might even like us, although they'd be wise to make the usual anti-American noises in public). But with respect to recompense, they're certainly no worse than either Europeans or Asians.
The difference is that during the reconstruction of Western Europe and Japan, they were purchasing American goods for the reconstruction and development of their economic stability thereafter. Therefore, much of that money returned to the U.S.. The boost in the American economy extended well beyond the years of the Marshall plan which ended in 1952. The U.S. post-WWII boom was fired by European demand for goods. That has not been nor will it be the case in the ME, nor will they cut us any deals on oil as a gesture of gratitude. The Iraqi people have been notably ungrateful and the Iraqi government lacks the institutions to build the infrastructure needed for their participation in trade levels that would benefit anybody, including Iraqis!! You can lead a camel to the oasis, but making the beast drink requires an undefined, unobtainable skill set. Arabs are willfully backward and fully intend to stay that way. The best way to handle them is to stay out of their way when they have a hankering to kill each other while killing as many as we can with plausible deniability.
