Moammar Gaddafi's death makes for an interesting punctuation mark in the ever-evolving U.S. approach to war. The key choice: should it be an exclamation point ("We got him! And not a single American died!) or a question mark ("Did we just get lucky? Is this a template for how the U.S. should wage future wars?").
We shouldn't over-learn whatever lessons there are to be gleaned by Gaddafi's demise and the joyful crowds gathering in Tripoli and other Libyan cities. But neither should we be shy about exploring what they might be.
