There is no doubt that America remains the premier political, economic, military power in the world, and I both expect and count on it remaining so, because I think that's certainly in our best interest but also the best interests of the world.

Ethical decisions ensure that everyone's best interests are protected. When in doubt, don't.

I learned to be far more skeptical of what I'm told by presidents, no matter who the presidents are, and also to be much more cautious, always, in any action or vote that could lead to the use of American military power and most particularly what we call 'boots on the ground.'

The United States military, because of people like you, can do things for a troubled world that no one else can do. And I am profoundly grateful,

We have to knock down the barriers erected by greed, special interests, powerful forces.

I think the primary message to the world is that the United States is going to remain the strongest military power in the world.
