I try never to get too high when things are going well. I try never to get too low when things are going poorly. I try to keep an even keel.

This counter-terrorism campaign will be waged through a steady, relentless effort to take out Isil wherever they exist, using our air power and our support for partner forces on the ground. This strategy of taking out terrorists who threaten us, while supporting partners on the front lines, is one that we have successfully pursued in Yemen and Somalia for years.

As Iraqi forces continue the liberation of Mosul, I'm pleased that NATO will be meeting the commitment we made in Warsaw to begin training additional forces in Iraq.

Even as we do all that's necessary to ensure Israel's security, even as we are clear-eyed about the difficult challenges before us, and even as we pledge to stand by Israel through whatever tough days lie ahead, I hope we do not give up on that vision of peace. For if history teaches us anything, if the story of Israel teaches us anything, it is that with courage and resolve, progress is possible. Peace is possible.

The world only makes sense to me given my life and my background if, in fact, we're not just an assortment of tribes that can never understand each other, but that we're, rather, one common humanity that can meet and learn and love each other.

We may never understand what leads anybody to terrorize their fellow human beings. Such violence, such evil is senseless. It's beyond reason.

I believe that this country succeeds when everyone gets a fair shot, when everyone does their fair share, when everyone plays by the same rules.
