Out of struggle very often comes victory.

America cannot do most of what needs to be done alone. You need friends. And we have good friends around the world. We have friends with whom we share values in Europe and Asia - thanks to the forward march of democracy - in Latin America, in Africa, and increasingly in the Middle East.

If you're always in the company of people who agree with you, you're going to think of people who don't agree with you as venal or stupid. I constantly tell my students that if they're in the company of people who always say "amen" to what you say, find other company. And that is the source of illiberalism, when you are unable to listen to someone who thinks differently. That's when democracies are in trouble.
