Will Libya turn into large-scale Srebrenica?

As the mentally ill Libyan dictator takes over one by one the rebellious cities and massacres their freedom-loving residents, I wonder, will the world let him finish his job and reinstate his reign by large-scale terror? Why not impose what the opposition is asking for – a no-fly zone?
Of course, the rebels also made a mistake. They waited for too long before making their plea. Now, they are learning the hard way that having the moral superiority does not guarantee military success, while having an air force does. Anyway. Now, what is the so-called free world intending to do?
I am disgusted by the hypocrisy of politicians of different countries who keep talking about how UN Security Council must approve the no-fly zone, knowing very well that Russia and China would impose their veto. I am saddened by the Americans’ abdication from their (purely moral) duty as the world’s sole democratic superpower. And I am outraged by the Europeans’ inclination just to watch as a genocide is carried out next door, as they did in Srebrenica years ago.
Why don’t we, citizens of democratic countries, press our governments towards military action to save the Libyans?
