We're well aware, and we have been for a long time, that there is a real threat from adversaries, state actors, non-state actors, to hack us, influence us, destroy stuff through cyber means. Because cyber threat has been understood for a while, it's longstanding, it's a concern.

What I would say about me is: What you see is what I get.

I spend every day up at the United Nations where I have to interact with 192 other countries. I know how well the United States is viewed.

Be who you are. If you spend all of your time worrying about how people view you, you will not be either faithful to yourself or effective in what you're trying to do.

We know that weapons, heavy weapons continue to flow across the border from Russia into Ukraine. And we have now, in recent days, indications that Russians - Russian military units themselves have, on occasion, fired into Ukraine.

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.

It's not the day in which I grew up, long time ago, where we had three news networks. No cable, no social media, no internet. Where what you see is what you got. We had basically straight journalism. We don't have that anymore.
