Lying offshore, ready to act, the presence of ships and Marines sometimes means much more than just having air power or ship's fire, when it comes to deterring a crisis.

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 tried to do the same thing with my colleagues when I was Secretary of State.

The bottom line in all of it is that, in life, it's all about people.
