I'm not active in politics. I vote as a citizen. And if somebody cares to know what my opinion is at the time of the election, I might or might not share it publicly.

Only when you have got a clear statement of what you want to achieve, do you ask yourself how you are going to achieve it. In the military we are taught never to go for a single answer, no matter how obvious that might be.

There's no doubt in my mind, though, that the Iraqi people would be better off with a different leader who did not waste their oil on weapons, as opposed to education, as opposed to healthcare, as opposed to food, as opposed to roads, as opposed to clean water. It is really sinful, a crime, what Saddam Hussein has done with the wealth of the Iraqi people over the last 30 years.

My responsibility, our responsibility as lucky Americans, is to try to give back to this country as much as it has given us, as we continue our American journey together.

Don't take counsel of your fears or naysayers.

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.

We are not shrinking from talking to Saudis or anyone else in the region, but it is up to each nation in the region to decide on its own how it will proceed and at what pace. There are other nations in the region that had similar policies to Saudi Arabia that are starting to make changes, such as Bahrain, Kuwait, Qatar, Morocco. And so it takes time but when you see the need for such changes, then changes tend to follow.
