The problem with the president:
"The only thing that worries me is your optimism," Aznar said.
"I'm optimistic because I believe I'm right," Bush replied.
Notice that Bush has no concept that even if he's right, bad things could ensue. There is no cost-benefit analysis here, no weighing of options, no thinking through of unintended consequences, no understanding of the inherent tragedy of human affairs. Bush might be the least temperamentally conservative president in the White House since Wilson.
