Well, I think by any expectation South Africa has come a tremendously long way. We've seen a society that many people thought couldn't withstand a peaceful transition to democracy without a great deal of violence, in fact, make that transition and do it in relative peace and security.

I think people have confidence that I will fairly and accurately represent their point of view to the President, and that I'm not going to put a spin on it, even if I may disagree with it.

I think it's very, very important that in foreign policy and national security decision making, as in any other realm, that there be a range of diversity that reflects the full complexity of America. We should draw on those experiences to inform our decision making.

President Obama has got the most moderate temperament.

The United States of America is the leading power in the world. Our friends and our adversaries respect us in large measure because they know that we are steady. We are fact-based. We are serious.

I've been very lucky to have had a supportive family, a great education, enormous opportunity and challenge.

I think one of the real issues that we're faced with is how we consume news, how the media is perceived, how fake news is gaining a degree of currency without criticism that is dangerous, in my judgement.
