This week I've travelled more than 15,000 miles from America to China to Burma to Australia. I have no idea what time it is right now.

We made America more respected around the world, took on the mantle of leadership in the fight to protect this planet for our kids, and much, much more.

They assert that their program is purely peaceful. . . . We want them to demonstrate clearly in the actions they propose that they have truly abandoned any nuclear weapons ambition.

We're not going to deputize a whole bunch of American citizens to start grabbing people or turning them in, in part because the ordinary American citizen may not know whether or not this person is illegal or not. But, you know, the notion that we're going to criminalize priests, for example, or doctors who are providing services to individuals, and throw them in jail for doing what their calling asks them to do, which is to provide help and service to people in need, I think that is a mistake. I think that's out of America's character.

I don't believe people should to be able to own guns.

For the first time, preventing nuclear proliferation and nuclear terrorism is now at the top of America's nuclear agenda.

I think that there have been a number of public figures where you start hearing commentary that is dangerous because what it starts doing is it starts dividing us up as Americans.
