No other advanced nation endures this kind of violence. None. Here in America, the murder rate is three times what it is in other developed nations. The murder rate with guns is ten times what it is in other developed nations. And there's nothing inevitable about it. It comes about because of decisions we make or fail to make. And it falls upon us to make it different.

Four years ago, I promised to end the war in Iraq. We did. I promised to refocus on the terrorists who actually attacked us on 9/11. We have. We've blunted the Taliban's momentum in Afghanistan, and in 2014, our longest war will be over. A new tower rises above the New York skyline, al Qaeda is on the path to defeat, and Osama bin Laden is dead.

What the Paris agreement now does is say to China and India and other countries that are potentially polluting, come on board. Let's work together so you guys do the same thing.

We've evolved a lot since 9/11 also, in terms of our law enforcement capabilities, our intelligence capabilities, military, counterterrorism.

These days, the House Republicans actually give John Boehner a harder time than they give me. Which means orange really is the new black.

I'd like to think that "President Obama believed deeply in this democracy and the American people."

To restore America's competitiveness, we must recruit a new generation of science and technology leaders by investing in diversity.
