I think we know this much about Donald Trump so far: He believes he's a deal-maker. He likes to bargain. Part of bargaining is that you talk really tough. You ask for the moon, you settle for the topsoil. He says - he beats up on the Mexicans, he beats up on the Canadians, but the point is not to abrogate the treaty and have the two of us basically putting up walls and blocking trucks at the border.

Anything greater than 350 of parts of carbon dioxide per million is more than the planet can safely deal with. It is what's overwhelming our climate system. Because we've been going up about three parts per million per year. And eventually, we will always be above 410, and then above 420, and above 430. We just keep pouring more carbon into the atmosphere.

America needs strong borders and extreme vetting, NOW. Look what is happening all over Europe and, indeed, the world - a horrible mess!

NAFTA is a horrible agreement, one of the worst trade deals ever. It's just one of the worst. Although TPP, which I terminated before it got signed - before it got finished, someday hopefully people will be thanking. That would have been one of the great disasters of all times, in terms of trade.

In America, we have a divided nation. We have a very divided nation.

I never met Putin, I don't know who Putin is. He said one nice thing about me. He said I'm a genius. I said thank you very much to the newspaper and that was the end of it. I never met Putin.

I think NATO is obsolete. NATO was done at a time you had the Soviet Union, which was obviously larger - much larger than Russia is today. I'm not saying Russia is not a threat. But we have other threats. We have the threat of terrorism. And NATO doesn't discuss terrorism. NATO's not meant for terrorism. NATO doesn't have the right countries in it for terrorism.
