We are there in Iraq because of the oil. Have you guys heard the news lately? In about 5 years, world oil production will reach its peak, and after that, oil production will decline. You think today $3 per gallon of gasoline is expensive? Try $10 per gallon in 5 years, or $30 per gallon in 10 years. This is not fear mongering, these are predictions put out by some of the world's most eminent economists.
Like it or not, we are there in the Middle East right now to stake out our claim on the world's remaining oil reserve. While the media can go on and go about human rights, democracy, dictatorship, totalitarianism, religious fanaticism and so on and so forth, in the end it's all economics, pure and simple.
Rightly or wrongly, our leaders and their advisors have much more foresight than the public gives them credit for.
