We [USA] need to deal with our problems here at home if we're going to be strong enough to lead abroad.

We can't live true to our set of values unless American educational system is strong. I really believe that if we don't get that right we will not compete because we won't believe that our people can compete, and we'll turn inward. We won't lead. That will be bad for the world.

You have to have a strong sense of your values and a strong sense of who you are, because there are a lot of events and a lot of people who will pull you in this direction or that direction.

If the strong exploit the weak, democracy will not be stable.
