Saudi hijackers first came into contact with al-Qaeda and went through Terrorism 101 when they signed up for the jihad in Afghanistan.

What we do know is that the planet is going from 7 billion people today to 9 billion. More people want to live like us, drive American- size cars, live in an American-size home, and eat American-size Big Macs. What does that mean? It means that energy demand is going to be going up.

The country that owns green, that dominates that industry, is going to have the most energy security, national security, economic security, competitive companies, healthy population and, most of all, global respect.

The Middle East would always be an important trading partner in just a market sense, like America is a big market for us, Asia is a big market, Europe is a big market. You are going to have hundreds of millions of consumers there, from just a standard market point of view, from a very narrow American point of view.

Change your leaders, not your light bulbs.

I don't think that stability and the status quo go together at all, not in a flat world where people are integrated, where women are assuming new roles, where young people want to be consulted and participate. I think the trick is to open up, move down the path of reform, do it in a way that is consistent with your own society's stability and culture, and just don't think you can do nothing.

So what am I? I guess I would call myself a sober optimist...If you are not sober about the scale of the challenge, then you are not paying attention. But if you are not an optimist, you have no chance of generating the kind of mass movement needed to achieve the needed scale.
