Janet Tavakoli dissects the influence of fundamentalist Islam on global terrorism based on her experiences as an American woman living in Iran during the tension-fraught Islamic Revolution and her subsequent research on terrorism by both Sunnis and Shias directed towards each other and towards infidels. She debunks the narrative that fundamentalist Islam is a religion of "peace." Muhammad, regarded by Muslims as the perfect man, led a violent band that raped and murdered. He murdered resisters, traded slaves, took multiple wives, and consummated a "marriage" to a six-year-old girl when she was nine-years-old. The ideology of fundamentalist Islam has been responsible for multiple ongoing acts of terrorism in the United States and the rest of the world. Muslim clerics from multiple countries and cultures, at the top of Muslim hierarchy, issue death fatwas and sponsor acts of terrorism. Apologist claim militant Islamists take ideas out of context, yet Islamic texts are written in Arabic, and Muslim clerics who speak Arabic as their mother tongue are some of the worst offenders. The ultimate goal of fundamentalist Islam is to convert the rest of the world to Islam, if necessary, by force. Tavakoli makes the case that fundamentalist Islam and its interpretation of sharia law are incompatible with laws of the United States, a genuine clash of civilizations.
