 Before you will see them on the ground to exercise, they need to communicate, so we need to talk to each other, we need to understand each other. So you see, it is the easiest way to understand interoperability. We are stronger together, and we are ready for future challenges here in Europe. These kinds of exercises are critical. We've got to keep training, and so I think everything you saw out here today on this drop zone is a great example, and I think it makes it very clear to everyone why this is so important and what we can accomplish. When you look out and you see aircraft flying from five different allied countries and all the different parachutes coming down from all the different allies that participated, it really drives it home, I think, how important this is and how much we can do.
