Islamic fundamentalism as a threat to Western civilization

At the turn of the twentieth century anarchists were seen as the main threat to the social and political order of the world. From the assassination of Tsar Nicholas II in 1881 to the assassination of Archduke Franz Ferdinand in 1914, anarchists murdered numerous prominent political leaders. A generation later Anarchism was subsumed in various left-wing political movements, but the threat of political assassination receded into the past. It is to be hoped that the same will happen to radical political Islam and self interest combined with common sense will prevail. I can't wait!
