This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book considers security in relation to the political sector in terms of processes of democratization in the region and demands of new groups for wider and more meaningful access to political decision making. It establishes a theoretical context for redefining security in the Middle East by considering a range of concepts, debates and theories that have traditionally been absent from the field. The book provides an analytical model for redefining national security as a theory and as a practice in the post-Cold War era. It explores fundamental issues related to Islamophobia and the West, the relationship between Islam and democracy, and circumstances for groups and parties to gain political power and effect social change through indigenous tools and symbols.
