Barack Obama: “Today we mark the 47th anniversary of 'Bloody Sunday,' the march from Selma to Montgomery, Alabama.”

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

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

When we choose, when we make that decision, I do believe – and there is evidence for this – that the world gets incrementally better, and that is a worthy goal and it’s worth fighting for.

People need to “rediscover what’s the story we tell about how we’re going to live together, and see each other, and recognise each other, and disagree, and yet, still care for each other”.
