Why is it always the fault of politicians when things begin to go awry? I'm sure our collective militarys had some input into the planning of the NFZ - if it wasn't possible or do-able for whatever reason then they should have said so at the outset.
If there are no defined political objectives then it's not possible to develop meaningful strategies, recent examples being Afghanistan and Iraq. I don't think there was any doubt that the no fly zone would be achieved swiftly, but then what? NATO troops on the ground?
