I always say that campaigning and governing are two different things.

We know the battle ahead will be long. But always remember that, no matter what obstacles stand in our way, nothing can stand in the way of the power of millions of voices calling for change.

Tough talk often draws headlines, but war rarely conforms to slogans.

What's good for America better damn well be good for General Motors.

Strong countries and strong presidents talk to their adversaries. That's what Kennedy did with Khrushchev. That's what Reagan did with Gorbachev. That's what Nixon did with Mao. I mean think about it. Iran, Cuba, Venezuela - these countries are tiny compared to the Soviet Union. They don't pose a serious threat to us the way the Soviet Union posed a threat to us. And yet we were willing to talk to the Soviet Union at the time when they were saying we're going to wipe you off the planet.

In Europe, where the terrorist threat is probably greatest at the moment, the amount of information-sharing that's been taking place, the effectiveness of law enforcement across borders gives us the ability to protect ourselves while still being true to the basic precepts of our liberal democracies. I hope that that continues, and it is something that I think we should be worried about.

We lose ourselves when we compromise the very ideals that we fight to defend. And we honor those ideals by upholding them not when it's easy, but when it is hard.
