The London bombings of July 7th, 2005, revived the debates that raged after 9/11. What relation did they bear to the foreign and war policies of the United Kingdom and the United States? Were they symptoms of a "cultural clash" between deep-seated "values" or signs of a social crisis at the root of the ongoing conflict? How should we analyze the present-day emergence of fanatical forms of Islamic fundamentalism?The title of the book alludes to the famous thesis on the "Clash of Civilizations." Achcar develops a counterthesis, namely that the clashes we are witnessing do not oppose civilizations, but their dark sides. Each civilization produces a specific form of barbarism, which tends to take over in periods of crisis. Accordingly, the Bush administration doesn't embody the values of Western civilization nor does Islamic fanaticism of the al-Qa'ida type represent Islamic civilization. The clash between them is a "clash of barbarisms" in which the main culprit remains the most powerful.The war of aggression and occupation in Iraq led to blatant manifestations of Western barbarism, most strikingly epitomized by the torture at Abu Ghraib, and inevitably nurtured fanatical Islamic and other counterbarbarisms.
