Et tu, Libya?

I would love to hear the West explain to me, in cogent terms, why it is "right, legal and necessary" to impose a No-Fly zone over a civil war in someone else's country in the name of humanitarian concerns, but it was "okay" to allow Darfur, Rwanda, Sri Lankan shelling of Tamil civilians cowering in a hospital, and the missile and mortar barrages against Israel?

And the Arab League is backing this, albeit not with the commitment of any forces.....if Saudi Arabia and Egypt aren't using all that wondrous American military hardware for the survival of brother Arab civilians in Benghazi, then maybe the US shouldn't sell them any more. Kind of a dress rehearsal for Iran, no? All those fighter jets but no will to use them.....
