The nature of catastrophe is after all reasonably unvarying in the way it ruins destroys wounds and devastates. But if something can be learned from the event - not least something as profound as the theory of plate tectonics - then it somehow puts the ruination into a much more positive light.
Of course there is no question that Libya - and the world - will be better off with Gaddafi out of power. I along with many other world leaders have embraced that goal and will actively pursue it through non-military means. But broadening our military mission to include regime change would be a mistake.
