There have been times where, let's say on LGBT issues, when we were trying to end Don't Ask, Don't Tell, and I got the Pentagon and Bob Gates, a Republican holdover from the [George W.] Bush administration, to authorize a study of how you might end Don't Ask, Don't Tell, headed up by Jeh Johnson, who at that time was a council to the Justice Department. And it was going to take a year to conduct that study, issue a report, and figure out how it might be implemented, what effect it would have on unit cohesion and military effectiveness.

One of the gratifying things, I think, about the end of my presidency even though admittedly my successor ran against a lot of what we stood for, is when you look at the individual issues and the progress that we've made on a lot of those issues, we got the support of a pretty decent majority.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.

In order for us to solve many big problems around the world, it is in our interest to work with Russia and obtain their cooperation.

I believe in term limits for presidents because I think that there is no doubt I'm a better president now than I was when I start. I would argue that I am the best president I've ever been over the last year or two. My team is more effective than it's ever been.But what is also true is that number one, this is grueling.

The ultimate goal is two states for two people: Israel as a Jewish state and the homeland for the Jewish people and the State of Palestine as the homeland for the Palestinian people - each state in joined self-determination, mutual recognition, and peace.

My job is to communicate to the American people that the Muslim world is filled with extraordinary people who simply want to live their lives and see their children live better lives. My job to the Muslim world is to communicate that the Americans are not your enemy. We sometimes make mistakes. But if you look at the track record America was not born as a colonial power, and that the same respect and partnership that America had with the Muslim world as recently as 20 or 30 years ago, there's no reason why we can't restore that. And that I think is going to be an important task.
