The Middle East changed dramatically. This is an opportunity in the midst of this new world to make a different kind of decision. He is optimistic. The president is very honest. Sometimes he's pessimistic, and he'll let people know. Again, he's a transparent man, which sometimes can be unusual. We're not used to always hearing it, but it's extremely helpful. So while I don't know the detail of what makes him optimistic, I know to trust him. I know to not second guess him. I know to understand that he's in the midst of something that can change every day. But the changes that he's been able to bring about have been brought about by the power of his personality and leadership, along with the support of an American government that is in line and embraces what he wants to accomplish.
