Leadership is the art of accomplishing more than the science of management says is possible.

It's not just a matter of whether you support Obama or Romney. It's who they have coming with them. I always keep my powder dry, as they say in the military.

Don't be afraid to challenge the pros, even in their own backyard.

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

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.

What we would be committed to would be a representative government where all the Iraqi people decide who should lead their nation, and lead it in a way that keeps it together as a single nation and where all parts of the nation - Shia, Sunni and Kurds - are able to live free and in peace and believe that their interests are represented by the government.

Our model of politics is one that it is inclusive of all members of the society; all should be represented. That is the nature of our democracy.
