As a leader you set the tone for your entire team. Communicate your vision.

I worked with the Nato Military Committee. The Head of the Luxembourg Armed Forces had equal standing with me, and I had to respect that. He was the leader of the armed forces of a sovereign country. I had to make sure he never thought that I was looking down on them, merely because they had less power than we did. With that kind of approach you can develop bonds of trust. I tried to do the same thing with my colleagues when I was Secretary of State.

Failure is a part of life and you have to learn to deal with it. Failure is something that is part of life's cycle and it's from failure that you gain life experience.

With respect to where we are now, we have a voluntary army. And if we ever go back to conscription I hope that at time it will be the kind of conscription that was put in at the end of the Vietnam War. And that is, everybody is equally liable to be called to serve the nation in time of conflict.
