I don't want to make promises, not knowing what the situation's going to be three or four years out.

When it comes to crime, the violent crime rate in America has been lowered during my presidency and any time in the last three, four decades.

I've always viewed the Paris Agreement as a starting point. If you look at all the commitments that have been made by all the countries, it's still not sufficient to deal with the very dangerous situation we face. What it has done is that it created an architecture whereby as technology improves, as we find new clean sources of energy, as we make our economies more efficient, then gradually we can turn up the dial and improve the outcomes of Paris.

I do want to once again speak directly to the Iranian people. Yours is a great civilization with a vibrant culture that has so much to contribute to the world - in commerce and in science and in arts.

Following the nuclear deal, you, especially young Iranians, have the opportunity to begin building new ties with the world.
