And now, well, Vietnam is one of the most wonderful places to go in the world. People love going there; they love the people. And we all survived: they survived, we survived. People will survive. If you can just stop shooting at them, they really do pretty well.

It's the right idea for a human to live in peace, and a peaceful nature is a proper thing. For children to be concerned about going to school, worried about what could happen to them at school, that makes for a horrible moment. It's just a horrible place for us to be at.

The thing that's so powerful about students is that, when you haven't had your idealism broken yet, you're able to speak from a place that has no confusion, where there is a clear set of values.

But there are idealists left over the age of 18, I'm sure of it. Idealism is a voice that's inside of you; it's your conscience. That can really deteriorate along the way, depending on the road that you follow, and it can become almost dysfunctional, but it's there. Everyone has it. Sometimes it's just a whisper, but, in some people, it's a shout.
