All the partners have a different geopolitical environment. They all tend to be NATO—five of them are in Europe, and Australia, Canada, and the U.S. are not, obviously—but I think we've shared a similar apprehension about the uncertainty of the future development of weapons systems in China, Russia, and other parts of the world that are not necessarily directly the threat, but they're exportable to places and to people who are very unpredictable. It's really impossible to predict where these things would go and where you would face them, in what environment, or even when.
Is this our last manned fighter? I don't know. Clearly, people have looked hard at whether you can do it with UAVs and other things. Just airspace coordination issues today are extremely difficult to manage without a manned fighter, so I think the short answer is the nine countries are still at that common conclusion.
