My central focus is what are we doing to protect the American people and the American homeland? Afghanistan and Pakistan are critical elements in that process.

Whether our forebears were strangers who crossed the Atlantic or the Pacific or the Rio Grande, we are here only because this country welcomed them in and taught them that to be an American is about something more than what we look like, or what our last names are, or how we worship.

For the sake of our economy, our security, and the future of our planet, I will set a clear goal as President: in ten years, we will finally end our dependence on oil from the Middle East.

The Internet and Twitter and all these things are very powerful, but it also means sometimes that instead of having a dialogue we just start calling folks - calling each other names. And that's true on the left or the right.

What we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return

The United States is not, and never will be, at war with Islam.

What we have done, I think, is build a model from a lot of hard lessons in Afghanistan and Iraq but in other places around the world, where we are working with them in an advisory capacity.
