Throughout history, diasporic communities have been susceptible to a variety of forms of radicalization. Indeed, even in the pre-Christian era, ethnic and religious diasporas were prone to religious and separatist radicalization. Since the end of the Cold War, ethnonationalism has continued to fuel radicalization within some diasporic communities. With respect to contemporary global terrorism, militant Islamism, and in particular, its Salafist-Jihadist variant, serves as the most important ideational source of radicalization within diasporas in Western Europe and North America. Within the global North, this radicalization has frequently pitted the political desirability of relatively liberal immigration politics against the core requirements of internal security.
