Today, natural gas now outstrips coal as the leading provider of electricity in America. If this is as big as people believe it is, natural gas will soon be powering trucks and marine ships. Maybe even standard commercial cars that people use at home through compressed natural gas, other gas to liquids.

I think that the drama of people rising up demanding their own freedom is one that resonates very deeply with America. I think that President Barack Obama has tried and would like to find a way to relate to the Arab Spring, but I think he also wants to be, rightly, very careful that we don't take it over. It is very important that they own this. He is trying to influence it this way but without, "We're so never going to go to the extreme of Iraq and putting boots on the ground again."
