Violence has to end. And Israelis have a bright to defend themselves against any violence that is attacking innocent people with a knife in the old city in Jerusalem or elsewhere. No country should be under siege like that.

Climate change is real. The science is compelling. And the longer we wait, the harder the problem will be to solve.

This revolution began with young people in Syria demonstrating because they wanted a future. They wanted opportunity, education, and so forth. They went out and they did it. Thugs came out and beat them up. The parents got angry that the thugs beat the kids up, and they went out and demonstrated, and they were met with bullets. They were killed. That's how this began.

That's what I am standing up for - Israel's future as a Jewish and democratic state living side-by-side in peace and security with its neighbors.

We cannot continue to see the Middle East in the context of 9/11. We must see it in the context of 2011.

We need a leader who has a sense of balance, an understanding of the ebb and flow of history and a sense of our country's unique place in it. This is a foreign policy debate, and you cannot conduct foreign policy without a sense of what we are fighting for. And any President who can reduce the conduct of this country's affairs to a morning's attack by a bunch of demented fascists does not, in my view, understand what this great nation is all about.

I will never conduct a war or start a war because we want to; the United States of America should only go to war because we have to. And if you live by that guidance, you'll never have veterans throwing away their medals or standing up in protest.
