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.

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.

We will fight anyone who wishes to impose a totalitarian system upon a free society, and we will always prevail. But we will not do so with a fear-stricken administration which seeks to deprive us of freedoms in the name of 'defending' us from the terrorists, who also seek to deprive us of our freedoms.

We have to create a process which has legitimacy for the people of Syria. And we have to have a process where the Russians and the Iranians and the neighbors - all of them, Saudis, Turks, Qataris, a very complicated brew - that you have to bring them together and they can find agreement. That's the fundamental premise of the Geneva Communique that you will have, by mutual consent, a process of transition.

I know something about aircraft carriers for real.

I've met foreign leaders who can't go out and say this publicly, but boy, they look at you and say, you've got to win this, you've got to beat this guy, we need a new policy, things like that.

You can't play sports without losing sometimes and, in losing, you learn something about grace and how to act under pressure.
