Perle, Bolton and co often pontificate on the unique moral evil of terrorism. But in their contempt for human life and their appetite for war they are not that different from Osama bin Laden. Unlike Osama, they will not be found in the Hindu Kush carrying a Kalashnikov. They are war trolls, endlessly manipulating the public from TV studios. In this sense they are more like the Roman senators who grew rich and fat while the legions went out to ‘create a wasteland and call it peace’, as Tacitus once put it.
