We've gotten a long way on missile defense. We know how to do it. We know how to take down incoming warheads, but we need to do a lot more work in order to be - to deploy a system that'll defend the United States against those kinds of limited strikes that might be possible by a nuclear armed North Korea or Iran.

Remember, success for a politician is 50% plus one. You don't have to have everybody on board.

I worry very much that we're in a situation now where there doesn't appear to be any limitation whatsoever in terms of the spending commitments that Obama's administration wants to make. Vast expansion in terms of the deficit, but it also says a lot about what they intend for the role of government in the society.

I think the record speaks for itself. These are two individuals who have been for the war when the headlines were good and against it when their poll ratings were bad.

We have to deal with this new type of threat in a way we haven’t yet defined. . . . With a low-probability, high-impact event like this . . . If there’s a one percent chance that Pakistani scientists are helping al Qaeda build or develop a nuclear weapon, we have to treat it as a certainty in terms of our response.

I'm not apologetic with respect to the policies of the Bush administration. I think we basically got it right.

I reached a point towards the end on the old heart where I had trouble getting out of a chair. All I wanted to do was get out of bed in the morning and walk to my office and sit back down in the chair. Now I throw 50 pound bags of horse feed in the back of my pickup truck and I don't even think about it. I'm back doing those things.
