When I was the director of Central Intelligence in the early '90s, I tried to get the Air Force to partner with us in building drones. And they didn't want to, because they had no pilots.

Things have gotten so nasty in Washington.

There is no international problem that can be addressed or solved without the engagement and leadership of the United States and everybody in the world knows that, its just fact of life. So sometimes I think we could conduct ourselves with a little more humility.

There's a lot of books out there about how you lead change in business, but I've certainly not seen any... on how you do that in public institutions.

I've been very sensitive for a long time to the repeated pattern, during economic hard times or after a war, of the United States' essentially unilaterally disarming.

And so the greatest of American triumphs... became a peculiarly joyless victory. We had won the Cold War, but there would be no parades.

The United States has been a global power since late in the 19th century.
