Perle expressed regret of his support of the invasion and faulted the "dysfunction" in the Bush administration for the troubled occupation. "I think now I probably would have said, 'Let's consider other strategies for dealing with the thing that concerns us most, which is Saddam supplying weapons of mass destruction to terrorists'. The decisions did not get made that should have been. They didn't get made in a timely fashion, and the differences were argued out endlessly. At the end of the day, you have to hold the president responsible."
