Ayaan Hirsi Ali joins Peter Robinson to discuss her new book, The Challenge of Dawa: Political Islam as Ideology and Movement and How to Contain It, and her views on the challenges facing Western civilization in regards to political Islam. She argues that Islam needs to be separated into two different parts, one part of religion and the other part, political philosophy. She concedes that many aspects of the religious part of Islam are peaceful but argues that the political side is much more concerning due to its focus on Dawa, which means “to plead or to call non-Muslims to Islam.” This call to convert people to Islam is what she argues was a driving force behind the spread of Islam throughout history. She discusses the critiques of the philosopher Karl Popper of communism and fascism and how they relate directly to the ideologies of Islam. She argues that the language of appeasement often used toward radical Islamic terrorism is too gentle and that discussions of how to deal with Islam need to be considerably franker.
