In this new, hyper competitive age, none of us, none of us can afford to be complacent.

One of the challenges over the last decade is America has done experiments in nation building in places like Iraq and Afghanistan and we've neglected, for example, developing our own economy, our own energy sectors, our own education system. And it's very hard for us to project leadership around the world when we're not doing what we need to do.

More people are realising that ISIL's not a caliphate. It's a crime ring.

I will continue to believe that Israel's security is paramount.

I always say that campaigning and governing are two different things.

In the end, that's what this election is about. Do we participate in a politics of cynicism or a politics of hope?

The problem is that, over time, big pieces of business that have to get done without leadership from Washington, don't get done.
