This system, built on free markets, free trade and free peoples and American protection, that's what got us from the end of World War II to the extraordinary events of the end of the Cold War and a system that was one of prosperity and peace for a lot of people, including for the United States.

Diplomacy, if properly practiced, is not just talking for the sake of talking.

The most important lesson I think I could impart is don't let anyone determine what your horizons are going to be. You get to determine those yourself. The only limitations are whatever particular talents you happen to have and how hard you're willing to work. And if you let others define who you ought to be, or what you ought to be because they put you in a category, they see your race, they see your gender and they put you in a category. You shouldn't let that happen.

I believed Afghanistan was always going to be hard. It's the fifth poorest country in the world. And when you fly over it, you realize that there's not much there. And, of course, it has the problem, too, of being on that border with Pakistan in basically an ungoverned region that has given the terrorists a staging ground. So it's a very difficult place. But I do believe that the mission there can succeed if success is defined as helping the Afghans to prevent the Taliban from being an existential threat to the Afghan government.

You can never ask others to do something you would not do. That is integrity.
