The real goal of Shock and Awe in Iraq

I'm reading Shock Doctrine by Naomi Klein right now, and it's a very enlightening look at the U.S. involvement and how Milton Friedman's economic theories have played a role across the globe. Iraq was the ultimate testing ground for the theories Friedman espoused. As we now know, the experiment has gone very badly and has been a catastrophe for U.S. foreign policy.
