I think that one of the greatest challenges we have today is around education. One of the things that is dividing us more and more is whether you have good prospects or you don't. Do you live a neighborhood where the schools are good? If you don't, your kids may not read until the time they're in third grade. Do you at least have access to a community college that will give you job training skills so that if you don't go for four years you will at least come out with a decent job and a decent wage. Too many people don't have that opportunity.

Diplomacy, if properly practiced, is not just talking for the sake of talking.

I never much cared for politics. I love policy, and I love international policy in particular. I got to be Secretary of State; it really doesn't get much better than that. I love what I do. I love being a professor.

American national security and American economic interests, of course - every president, every secretary of state - that is the primary goal. As you are in this job and in the work, you begin to see, though, that in the long run, both American economic interests and American national security are better served when there are other decent countries in the world who are both your allies and even when your adversaries are acting more decently.

We have important things to talk to the Russians about, despite their meddling in our elections. I hope they're talking about a way to eventually end this horrific humanitarian crisis in Syria, end that war. The Russians have more leverage than we do. I hope they're talking about the fact that, if Kim Jong-un's long-range missiles can reach Alaska one day, they can also reach Vladivostok.

Our effort to build stability through authoritarians in the Middle East for 60 years had given us neither democracy nor stability.

I think all of us have really got to redouble our efforts, first of all, to pay attention to the K-12 crisis. The sad fact is that I can look at your zip code and tell whether you're going to get a good education. That's not fair. And secondly, I hope that all of us who were fortunate enough to have benefited will put our time, our resources and our efforts into making sure that kids, particularly kids without means, have a way to achieve.
