 So the topic for the panel was anti-access area denial and how it affects basically the NATO alliance. And this is what this really is a shorthand for, the modernization of possibly antagonistic forces that NATO might have to face on a battlefield someday, in a nautical battlefield. Some of the questions were very good because they got at the underpinnings of what are the strategic implications of this. But the nice thing about the questions, too, is it made us think more about and really address some of the assumptions that we had made in putting together the briefs. That's always excellent. And again, this comes from war college graduates picking us apart.
