I’ve often said that global climate change is an issue where no one has the luxury of being “half-pregnant.” You either are or you aren’t. And so it is with climate change. You either understand and accept the science – or you don’t. Folks this isn’t a cafeteria where you can pick and choose and accept the science that tells us what is happening, but then reject the science that warns us what will happen.

I met with many of - a number of [Syrian] refugees in Berlin the other day, and I was struck by how educated, intelligent, and patriotic they are. They want to go back. They love their country. And there are so many of them still in Jordan and in refugee camps in Lebanon and in Turkey, that if you could create the climate within which they could begin to come back, I believe there is such a history of secularism within Syria, even tolerance within Syria, that if we can deal with ISIL, yes. That's the key. And with ISIL there, not a chance.

What we need now is not just a regime change in Saddam Hussein and Iraq, but we need a regime change in the United States.

I don't want to claim that God is on our side. As Abraham Lincoln told us, I want to pray humbly that we are on God's side.

As a public person, I've always tried to reflect what is embodied in our defining ideals as a nation about equality and fairness and justice and so forth.

America has an ability to try to make some things happen that other countries don't necessarily have.

People talk about [Bashar] Assad running Syria. He doesn't control his own country. He's down to about 20, 25 percent of the country. What is this fiction that he is somehow the only person who can save Syria? There's - with Assad there, there is no Syria. So that's what the Iranians and the Russians need to really begin to focus in on.
