As you say, things evolve. At least some of the ranges of goals I have heard go beyond the protection of civilians to in a sense freeze certain circumstances. So a division of Libya would result. And there is certainly the discussion about regime change--going as far as that.
Is it possible for someone under these rules of engagement to interpret them in that way, so in order to achieve those goals under the rules of engagement they could interpret that this is as far as one can reasonably go? Or you can go further on that. Is that part of the complication of any kind of effort like this?
