I really feel that if you look at our actions over the years, it's hard to come up with cases where we haven't eventually done the right thing from a science standpoint. I was thinking about that, and it's really that things take longer than maybe they should. Politics, of course, enter into the process of challenges, and so forth, and congressmen asking the administration why we're doing different things, but in my experience, the basic thrust of the direction in which we want to go, and in which we do go, is based on science, because that is the only rule that is going to kind of work in the end. That's what we want and that's the way we want other countries to treat us, and that's the way we have to treat them.
While people like to look for other reasons, at why it is that we're doing this or doing that, because they may not agree with our science or whatever, two scientists can disagree looking at the same thing, but I think it really is a sincere effort to keep the foundation of science.
