In my own country, many of the movies in recent years express our innate fears about what awaits us. They are apocalyptic visions that leave only a few people on earth-whole cities surviving under domes because we have depleted our natural resources. And often in these movies, for reasons that I question, we have space aliens who are always blowing up Washington, D.C., and the White House.

I feel that at this point in our country's history, it is important that we not reverse marriage equality, that we not reverse Roe v. Wade, that we stand up against Citizens United, we stand up for the rights of people in the workplace, that we stand up and basically say: The Supreme Court should represent all of us. That's how I see the court, and the kind of people that I would be looking to nominate to the court would be in the great tradition of standing up to the powerful, standing up on behalf of our rights as Americans.

I did put together the coalition to impose sanctions. I actually started the negotiations that led to the nuclear agreement, sending some much my closest aides to begin the conversations with the Iranians.

Never waste a good crisis...Don't waste it when it can have a very positive impact on climate change and energy security.

I am delighted to be here in these new [Council on Foreign Relations] headquarters. I have been often to, I guess, the mother ship in New York City, but it's good to have an outpost of the Council right here down the street from the State Department. We get a lot of advice from the Council, so this will mean I won't have as far to go to be told what we should be doing and how we should think about the future.

Of course, ISIS is a terrible organization that has to be defeated. And, of course, we need a strong military. But just as with every other agency of government, you know what, the military also has got to get rid of waste and fraud and cost overruns.

New York has done an excellent job. And I give credit - I give credit across the board going back two mayors, two police chiefs, because it has worked. And other communities need to come together to do what will work, as well.
