Those who are troubled by our existing programs are not interested in a repeat of 9/11, and those who defend these programs are not dismissive of civil liberties. The challenge is getting the details right, and that's not simple.

The notion that we would condition Iran not getting nuclear weapons in a verifiable deal on Iran recognizing Israel is really akin to saying that we won't sign a deal unless the nature of the Iranian regime completely transforms. And that is, I think, a fundamental misjudgment.

I think that today, faith drives so much of our politics, that I thought, "If you don't talk about it, you are missing a whole big part of what is going on politically."

Each side has legitimate aspirations - and that's part of what makes peace so hard. And the deadlock will only be broken when each side learns to stand in the other's shoes; each side can see the world through the other's eyes. That's what we should be encouraging. That's what we should be promoting.

The brain is a body part too; we just know less about it.

Part of the reason that our politics seems so tough right now and facts and science and argument does not seem to be winning the day all the time is because we're hardwired not to always think clearly when we're scared. And the country's scared.

To the extent that our political dialogue is such where everything is under suspicion, everybody is corrupt and everybody is doing things for partisan reasons, and all of our institutions are full of malevolent actors - if that's the storyline that's being put out there by whatever party is out of power, then when a foreign government introduces that same argument with facts that are made up, voters who have been listening to that stuff for years, who have been getting that stuff every day from talk radio or other venues, they're going to believe it.
