MELBOURNE – The international military intervention in Libya is not about bombing for democracy or for Col. Muammar el-Qaddafi’s head – let alone keeping oil prices down or profits up. Legally, morally, politically, and militarily, it has only one justification: protecting Libyans from the kind of murderous harm that Qaddafi inflicted on unarmed protestors four weeks ago; has continued to inflict on those who oppose him in the areas that his forces control; and has promised to inflict on his opponents in Benghazi and other rebel-held territory.
