I think that there's gonna be a lot of work to do in order to consolidate the transformations that I was interested in.

What we have done, I think, is build a model from a lot of hard lessons in Afghanistan and Iraq but in other places around the world, where we are working with them in an advisory capacity.

I do think that it is impossible for us to think only in terms of the Palestinian-Israeli conflict and not think in terms of what's happening with Syria or Iran or Lebanon or Afghanistan and Pakistan. These things are interrelated. And if we are looking at the region as a whole and communicating a message to the Arab world and the Muslim world, that we are ready to initiate a new partnership based on mutual respect and mutual interest, then I think that we can make significant progress.

The good news is that the Paris Agreement is not just a bilateral agreement between the United States and some other country. You have 200 countries who came together. It's an international agreement.

Every decision, every debate, no matter how important it is, with the same question: 'What does this mean for the next election? What does it mean for your poll numbers? Is this good for the Democrats or good for the Republicans? Who won the news cycle?' That's just how Washington is. They can't help it. They're obsessed with the sport of politics.

Ultimately, if you think about all the youth that everybody has mentioned here in Africa, if everybody is raising living standards to the point where everybody has got a car and everybody has got air conditioning, and everybody has got a big house, well, the planet will boil over - unless we find new ways of producing energy.

I would say of all the things that have happened during the course of my presidency the knowledge that you have hundreds of thousands of people who have been killed, millions who have been displaced, [makes me] ask myself what might I have done differently along the course of the last five, six years.
