But the most serious mistake consists of taking the form for the content: defining all the various terrorists and terrorisms of our time, with their contrasting and sometimes conflicting objectives, by their actions alone. It would be rather as though one were to lump together the Italian Red Brigades, the German Baader-Meinhof gang, the Provisional IRA, the Basque ETA, Switzerland’s Jura Separatists, and the National Front for the Liberation of Corsica; dismiss their differences as insignificant; label the resulting amalgam of ideological kneecappers, bomb throwers, and political murderers “European Extremism” (or “Christo-fascism,” perhaps?)…and then declare uncompromising, open-ended armed warfare against it.
This abstracting of foes and threats from their context—this ease with which we have talked ourselves into believing that we are at war with “Islamofascists,” “extremists” from a strange culture, who dwell in some distant “Islamistan,” who hate us for who we are and seek to destroy “our way of life”—is a sure sign that we have forgotten the lesson of the twentieth century: the ease with which war and fear and dogma can bring us to demonize others, deny them a common humanity or the protection of our laws, and do unspeakable things to them.
