The sledgehammer was also wielded elsewhere, notably in Libya, where the three traditional imperial powers (Britain, France, and the United States) procured Security Council resolution 1973 and instantly violated it, becoming the air force of the rebels. The effect was to undercut the possibility of a peaceful, negotiated settlement; sharply increase casualties (by at least a factor of 10, according to political scientist Alan Kuperman); leave Libya in ruins, in the hands of warring militias; and, more recently, to provide the Islamic State with a base that it can use to spread terror beyond. Quite sensible diplomatic proposals by the African Union, accepted in principle by Libya’s Muammar Qaddafi, were ignored by the imperial triumvirate, as Africa specialist Alex de Waal reviews. A huge flow of weapons and jihadis has spread terror and violence from West Africa (now the champion for terrorist murders) to the Levant, while the NATO attack also sent a flood of refugees from Africa to Europe.
