There's always going to be a limit. What I'm saying is there are sometimes people who aren't prepared to go to the limit that's been agreed to by a coalition or by an alliance. The limits are still established. We don't exceed those limits; there's no effort to exceed those limits. But sometimes individual nations will arrive and they won't be prepared to go to even that limit, so you do have to manage that. That kind of debate takes place in the North Atlantic Council and elsewhere as nations come to an understanding of what they're prepared to do. That's why they go through a process of asking for an initiating directive to do a plan. They then approve an operations plan and then approve an actual directive that allows the mission to take place, understanding as they're going along how that mission is being designed and evolved, and taking into account how a commander who is designing the mission will keep coming back and offering his guidance on how he thinks it should happen. Then there's the political guidance that would come from the alliance, which then would provide the limitations on what he can and should do.
