The best way to enhance freedom in other lands is to demonstrate here that our democratic system is worthy of emulation.

War may sometimes be a necessary evil. But no matter how necessary, it is always an evil, never a good. We will not learn how to live together in peace by killing each other's children.

What has happened at Guantanamo Bay... does not represent the will of the American people. I'm embarrassed about it, I think its wrong. I think it does give terrorists an unwarranted excuse to use the despicable means to hurt innocent people.

People didn't have money. They bartered; they'd trade eggs or pigs. It was just completely different.
