With respect to Russia, my principal approach to Russia has been constant since I first came into office. Russia is an important country. It is a military superpower. It has influence in the region and it has influence around the world.

We were still able to see the phone records of a potential terrorist cause, we held them, now you have to hope the phone company still has them, you have to argue with their chief counsel by the time you get access to it, and try to find out who they've been talking to before it's too late.

We have states. And we have cities. And we have counties. And we have the private sector. And - and so the country still works even when Washington's dysfunctional.

I am convinced that whenever we exaggerate or demonize, oversimplify or overstate our case, we lose. Whenever we dumb down the political debate, we lose. For it's precisely the pursuit of ideological purity, the rigid orthodoxy and the sheer predictability of our current political debate, that keeps us from finding new ways to meet the challenges we face.

One of the proudest things of my three years in office is helping to restore a sense of respect for America around the world.

The UK is an extraordinary partner for America and a force for good in an unstable world. I hope it remains strong, robust and united.

Any fool can have a child. That doesn't make you a father. It's the courage to raise a child that makes you a father.
