Difficult to know what to do for the best here. With memories of the Srebenica massacre still being invoked, it would be seen as a repeat performance if the UN stood back and let mad-dog Gaddafi's murderous bunch loose on Benghazi with almost a million citizens living there.He has promised to root out the rebels (ie: everyone)house by house. I suspect that the atrocities that would be visited on these civilians would evenutally prompt some form of UN action but it would be too late to save many innocent lives. I suppose the best hope is that the Libyan military depose Gaddafi rather than see their assets blown to bits over the next few weeks. Unfortunately we're told that the command structure of the Libyan army is dominated by Gaddafi loyalists and will protect their man to the bitter end.If boots on the ground are needed, then it's time for the Arab league to stand up and prove that they are not just a talking shop.
