We have to know who we are and know what we believe.

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.

We should learn to tolerate nuclear weapons of North Korea just like we did the Soviet Union.

The United States really only accounts for about 3 percent of the economic engagement with Russia. Europe is 40 percent, and so Europe's contribution to this pressure is far more than symbolic. It's very practical. And that's one of the many reasons why we have worked hard to remain in close coordination with our European partners.

I read a ton of paper every day. I read the newspapers, I read my intelligence materials, I read all the briefing materials. I read the newspaper in hard copy.

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.

The larger picture here is that a North Korea with nuclear weapons adds to the larger proliferation risk.
