Libya was a terrible mistake. You know, frankly, that's something that people ought to be thinking about in regard to Hillary [Clinton]. You know, they talk about Benghazi, which is very legitimate. Of course it is. But we should never have deposed [Muamar] Gaddafi. That was a terrible mistake.

Our biggest challenge in this digital age that we are entering is how do we effectively begin to train people for the jobs that are going to exist and not have them be stuck on jobs that are going to go away? And this is a big deal. And it requires the businesses of this country to, in my opinion, first of all, demand changes in the education system and also develop innovative, creative ways to have industries train people for the skills that are necessary for the jobs that are coming.

You know, whatever it takes. It's very important obviously from an economic point of view because of the need for innovation, for progress, to improve the standard of living of people. But I also think it's a critical issue in geopolitics too.

I mean, I don't have any more words.I've tried to do the best I can to lead by my actions in an appropriate way without recrimination or anything like that, because I'm a very happy person. I don't think I need to say any more than what I've demonstrated.

I don't make promises, by and large, that I can't keep.

To put all of your eggs in one basket is silly. We did that for a long time and I don't think it's very smart.

Any politician who is not a unifier is not somebody that I want to be for.
