We're up against the conventional thinking that says your ability to lead as president comes from longevity in Washington or proximity to the White House. But we know that real leadership is about candor and judgment and the ability to rally Americans from all walks of life around a common purpose, a higher purpose.

Iran will for sure have pledged to the international community that it will not develop a nuclear weapon, and now will be subject to an additional protocol, a more vigorous inspection and monitoring regime that lasts in perpetuity.

We have a historic opportunity to prevent the spread of nuclear weapons in Iran, and to do so peacefully, with the international community firmly behind us. We should seize that chance.

We can't, you know, use our military to make sure the planet doesn't get warmer. And so that kind of leadership, of being able to bring people together, to apply practical commonsense solutions based on facts, based on science, based on what works you know, that's been the approach I have taken consistently as a public servant. That's the kind of style that I think we need in the presidency right now.

What is a danger is that we stay stuck in a new normal where unemployment rates stay high, people who have jobs see their incomes go up, businesses make big profits. But they're learned to do more with less, and so they don't hire.

Nobody wants to put the creditworthiness of the United States in jeopardy. Nobody wants to see the United States default. So we've got to seize this moment, and we have to seize it soon.

No one built this country on their own. This nation is great because we built it together.
