NATO is built on security, but it's also built on values.

Success is not assured, but America is resolute: this is the best chance for peace we are likely to see for some years to come - and we are acting to help Israelis and Palestinians seize this chance.

I'm very proud that we stood for the proposition that no man, woman or child should ever have to live in tyranny. We believed in democracy and promoted it.

When I went off to college, I was expecting to be a concert musician. In music school I heard all of these kids who were just unbelievable. And I understand that you can be very, very good, but there's something that separates very, very good from great, and I knew that I wasn't great.

Our work has only begun. In our time we have an historic opportunity to shape a global balance of power that favors freedom and that will therefore deepen and extend the peace. And I use the word power broadly, because even more important than military and indeed economic power is the power of ideas, the power of compassion, and the power of hope.

We have important things to talk to the Russians about, despite their meddling in our elections. I hope they're talking about a way to eventually end this horrific humanitarian crisis in Syria, end that war. The Russians have more leverage than we do. I hope they're talking about the fact that, if Kim Jong-un's long-range missiles can reach Alaska one day, they can also reach Vladivostok.

I'm a great believer in the fact that as you get to know someone, it matters not what religious background they have, or what their nationality is, or where they came from. And I think that's how Americans really do relate to each other on a personal level.
