I think for one that Professor Tanenbaum meant to write that it was Engler who wrote
"“Bremer was sent to Iraq to build a corporate utopia,” Klein writes; “instead, Iraq became a ghoulish dystopia where going to a simple business meeting could get you lynched, burned alive or beheaded.” I'm not positive but i think that's what she meant .
I belive Engler is saying that a limit to Klein argument would be that the major corporations that were greedy for ways to profit from the war were not getting the profits they thought they would.
"The oil companies are not alone in finding profits to be more elusive than antcipated. The fiasco in Iraq has limited the profiteering ventures of of even those compaines that embraced the war and sought to benefit from it"
I believe he is saying that the war was fought for reasons that were essentially neoconservative.
Their attempts for geopolitical power were largely unsucessful, many nations in the world frown on the decision to invade Iraq. Our current President was against the invasion and it is a mess that is being cleaned up by the current administration.
edit- i felt like both Engler and Kein think that whatever the reason for the war, it was an unsuccesful venture whether for neoconservatives or for war profiteers. Meaining that i think that they both believe the war was a mistake and failure for the U.S., though i do think Klein would be more inclined to argue that it proved a success for businesses like Halliburton that profited.
