We are a great nation because we are a good people.

We believe in the dignity of every life, the possibility of every mind, the divinity of every soul. This is our true north.

The United States is the leader of the free world.

Iraq is the central battleground in the war on terror. The terrorists certainly know what is at stake, which is why they are pulling out all the stops to derail our efforts there. They know that a free and democratic Iraq is a serious blow to their interests.

When you're in your nineties and looking back, it's not going to be how much money you made or how many awards you've won. It's really what did you stand for. Did you make a positive difference for people?

I am a firm believer in free but fair trade. However the United States should not be on the losing end of trade agreements that are not enforced. It is time that we make China play fairly.

[On power:] Some people really have almost a disdain for that word. They feel it is alien to conscience. Power for power's sake, no. But the positive use of power for positive purposes is very important. You have to understand that. You've got to have a seat at the policy table if you want to make a difference.
