 We have a minute and a half left, so I'll ask you one final question. You mentioned the battle groups earlier. The president last night at the Mellon Auditorium discussed the four that were in existence prior to the full-scale invasion, the four new ones that have been put in place in the southern eastern flank of the alliance. We've seen what can happen under even short-term occupation by Russian forces in places like Bucha in Irpin. How confident are you that the four land forces concept can guard against such a contingency in, say, the Baltic states?
