That is the true genius of America-a faith in simple dreams, an insistence on small miracles.

No U.S. soldier ever dies in vain because they're carrying out the missions of their commander in chief. And we honor all the service that they've provided. Our troops have performed brilliantly. The question is for the next president, are we making good judgments about how to keep America safe precisely because sending our military into battle is such an enormous step.

No religion is responsible for terrorism. People are responsible for violence and terrorism.

If you look at Libya, I was deeply concerned about what would happen after Qaddafi was gone.

There's no question that a lot of Americans on both the right and the left are expressing some fears and frustrations about the dislocations brought on by globalisation. Many of those frustrations are legitimate and they need to be addressed.

For we, the people, understand that our country cannot succeed when a shrinking few do very well and a growing many barely make it.

There are legitimate concerns and anxieties that the forces of globalisation are leaving too many people behind - and we have to take those concerns seriously and address them. But the answer isn't to turn inward and embrace protectionism. We can't just walk away from trade.
