19 "Congress is all over the place," Gates says at one point. "And the Republicans are a perfect example. I mean, you've got the budget hawks and then you've got the defense hawks within the same party. And so I think there is no consensus on a role in the world."

This spring, when Obama announced a $400 billion reduction in defense spending, Gates got just 24 hours’ notice.
