From Losurdo - A critique of the category of totalitarianism:

Nowadays we constantly hear denunciations, directed toward Islam, of ‘religious totalitarianism’ or of the ‘new totalitarian enemy that is terrorism’. The language of the Cold War has reappeared with renewed vitality, as confirmed by the warning that American Senator Joseph Lieberman has issued to Saudi Arabia: beware the seduction of Islamic totalitarianism, and do not let a ‘theological iron curtain’ separate you from the Western world.

Even though the target has changed, the denunciation of totalitarianism continues to function with perfect efficiency as an ideology of war against the enemies of the Western world. And this ideology justifies the violation of the Geneva Convention, the inhuman treatment of prisoners in Guantanamo Bay, the embargo and collective punishment inflicted upon the Iraqis and other peoples, and the further torment perpetrated against the Palestinians. The struggle against totalitarianism serves to legitimate and transfigure the total war against the ‘barbarians’ who are alien to the Western world.
