Barack Obama: “Our commitment to NATO is the most important element of U.S. national security, as well as European security.”

And I will fight for that, even if I don’t always think it’s going to win.

I’m going to insist that we can do better than we’re doing right now.

If I had a blame pie for why politics is so polarised and why we're seeing a rise of populism in many places, it's because of that information that is going into our brains every day.

It is a decision about how do we face and embrace this finite amount of time we have on the planet.
