Obviously, what's happening in China right now is crucial, in the party congress, which as someone said has anointed a new emperor of China in President Xi. So there's the rise of China, and their active involvement in the United States internally in our business and financial realms. That certainly bears watching.

The Russians have to be celebrating with a minimal expenditure of resources and what they have accomplished. Of course, what's unfolded now, here, the leader of the lead of the investigation about potential collusion between Russia and the Trump campaign has been removed. So the Russians have to consider this as another victory on the scoreboard for them.

When I visited North Korea in November 2014, is that Kim Jong-un is not merely the head of state of the DPRK - the Democratic People's Republic of Korea, North Korea - he's also their deity. So, when you insult him as the head of state, you're also insulting the deity, which of course the regime plays to a fare-thee-well to the domestic audience there.

The president sets the tone. He creates the atmosphere, and that can be enlightened, progressive, or it can be intimidating, depending on what the president's agenda is. I think the other dimension of this that I worry about is impacts overseas with friends and allies, many of whom are very, very concerned about America's position in the world and whether or not it's going to continue its leadership, which has been the prevalent condition since World War II.

I think Trump's presidency represents a completely different model than what we're used to. And I think to your point, yes, he is a great communicator, you know? He uses Twitter to great effect. I just wish he could stick more to the truth, because it's a very effective way of communicating directly with the American people.

What I said was, ‘the NSA does not voyeuristically pore through U.S. citizens’ e-mails.’ I stand by that.
