Barack Obama: “Ultimately, global leadership requires us to see the world as it is, with all its danger and uncertainty.”

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.

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

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.
