Today I can declare my hope and declare it from the bottom of my heart that we will eventually see the time when that number of nuclear weapons is down to zero and the world is a much better place.

I think leadership is both a trained thing and a natural gift.

If a leader doesn't convey passion and intensity then there will be no passion and intensity within the organization and they'll start to fall down and get depressed.

Good leaders set vision, missions, and goals. Great leaders inspire every follower at every level to internalize their purpose, and to understand that their purpose goes far beyond the mere details of their job. When everyone is united in purpose, a positive purpose that serves not only the organization but also, hopefully, the world beyond it, you have a winning team.

It is the job of leaders to eliminate uncertainty.

Endeavors succeed or fail because of the people involved.

Foe means enemy. Now, will we have differences of opinion with the Russians? Yes. Will they get mad at us from time to time, and we get mad at them? That's part of the normal diplomatic relations.
