The big thing for drones is that there has to be a carrier that gets you within that location. What we're seeing in Ukraine are, of course, closer locations. Now there are some drones that are capable of extreme distances, but the reality is that the type of swarming we see occurring in Ukraine is not what we're really talking about.
Your question raises a critical point, which is that even if we get this infrastructure in place, we also have to add the thing that we're not thinking about, which is defending that infrastructure. As Madeleine knows—and she is one of the best people speaking on this—once we get the fibre optics in, we do have to defend that against the Chinese capability. Some of those icebreakers that came north already have it. You have to be able to defend it, so there is an added dimension for what we have to do. We haven't got to that stage yet in terms of NORAD modernization.
