So here's what I want you to know, and here's what I want all our men and women in uniform to know: Because of you, we are ending these wars in a way that will make America stronger and the world more secure. Because of you.

If we're going to prevent large parts of this Earth from becoming not only inhospitable but uninhabitable in our lifetimes, we're going to have to keep some fossil fuels in the ground rather than burn them and release more dangerous pollution into the sky.

We've got to be able to distinguish between dangerous individuals who need to be incapacitated and incarcerated versus young people who are in an environment in which they are adapting, but if given different opportunities, a different vision of life, could be thriving the way we are. That's what strikes me. There but for the grace of God. And that, I think, is something that we all have to think about.

The Democrats should not waiver on our core beliefs and principles.

I think that Mr. Snowden raised some legitimate concerns. How he did it was something that did not follow the procedures and practices of our intelligence community. If everybody took the approach that I make my own decisions about these issues, then it would be very hard to have an organized government or any kind of national security system.

I didn't have a perfect model, but I wanted to try to blend my own personal reflections and experiences with this broader canvas to see how a lot of the narratives we have about economy and foreign policy got stuck.

We will send an additional 475 service members to Iraq. As I have said before, these American forces will not have a combat mission - we will not get dragged into another ground war in Iraq. But they are needed to support Iraqi and Kurdish forces with training, intelligence and equipment.
