So far, the Arab revolts have vindicated the assumption that, given the structure of most Arab societies, toppling secular autocracies inevitably means opening the door to Islamic democracies. We saw that dynamic play out in Algeria in the early 1990’s, with the Islamic Salvation Front’s first-round victory in a parliamentary election (which prompted the cancellation of the second round); with Hamas’s electoral victory in Palestine in 2006; and, most recently, with the Muslim Brotherhood’s democratic rise to power in Egypt.
