We know that much of the training and the direction for terrorists comes from Pakistan and the border area with Afghanistan

I'm not going to be able to wave a magic wand and change everybody's thoughts. That's something that can only happen by people working on themselves and being held to account by the rest of us, but what Donald Trump's done really unleashed a lot of darkness and divisiveness.

I will take responsibility for any impression or anything I've ever done that people have legitimate questions about. But I think that it's fair to say there's been a concerted effort to convince people like that young man of something, nobody's quite sure what, but of something.

[Donald Trump] even said, well, you know, if there were nuclear war in East Asia, well, you know, that's fine have a good time, folks.

We have to use all of America's strengths to build a world with more partners and fewer adversaries, more shared responsibility and fewer conflicts, more good jobs and less poverty, more broadly based prosperity with less damage to our environment.

When people say, well, they disapprove, I'd like to know what the specifics are, because sometimes - and the president [Barack Obama] has admitted this - they may not feel like he's really explaining and understanding the emotion behind some of these fears [about Iran]. And that's a perfectly legitimate question for people to ask. But if you look at the results of where we are, I think there are some things I agree with and some things I don't agree with, and I think that's absolutely fair game.

Iraq both poses a continuing threat to the national security of the United States and international peace and security in the Persian Gulf region and remains in material and unacceptable breach of its international obligations by, among other things, continuing to possess and develop a significant chemical and biological weapons capability, actively seeking a nuclear weapons capability, and supporting and harboring terrorist organizations.
