A No-Fly Zone in Libya?

With the Arab League's request today to the UN to provide a no-fly zone over Libya, the US has moved closer to getting engaged in it's third simultaneous military intervention.  Under the circumstances, it is worth reading the questions George Will listed in his March 8 Washington Post article On Libya, Too Many Questions. I worry that, once again, militarily naive politicians will take us where the professional military knows better than to go.
