Bush's War on Iraq: Was it Just for the Photo Ops?

Paul Krugman asks "why is the failure to find any evidence of
an active Iraqi nuclear weapons program, or vast quantities of chemical and biological weapons ... a big deal? Mainly because it feeds suspicions that the war wasn't waged to eliminate real threats. This suspicion is further fed by the administration's lackadaisical attitude toward those supposed threats once Baghdad fell. For example, Iraq's main nuclear waste dump wasn't secured until a few days ago, by which time it had been thoroughly looted. So was it all about the photo ops? Well, Mr. Bush got to pose in his flight suit. And given the absence of awkward questions, his handlers surely feel empowered to make even more brazen use of the national security issue in future."
