This book develops a conceptual approach to understanding the face of contemporary terrorism as manifested in the recent attacks in Mumbai and Paris. By analyzing the historical evolution of terrorism and by offering case studies on different forms of terrorism in South Asia and elsewhere, the authors shed new light on the political strategies behind terrorist attacks, as well as on the motivations of terrorists. The case studies explore the redefinition of terrorism by the Iranian Islamic revolution, the spread of terrorism in Sunni Islam, the national jihadism in Pakistan, anti-Semitism as a main factor behind fanatical terrorist ideologies, and the case of the Tamil Tigers.
