I agree with you Trim Stab that a NFZ should be in order to achieve something tangible with measurable effects and a clear end state. The reality is that Air will be asked to do something to show resolve, piss off Gadaffi and give some hope to his opposition. The aims will be contradictory, confusing and different for each member of NATO. It's likely that the direction will be loosely worded and vague and refer to NFZ with little more clarity than that. NATO would be content just to get the show on the road.
