It still to a large degree lacks unifying theories and approaches that a new generation of scholars, specialists, and policymakers must grapple with. While there have been impressive advances in our substantive knowledge of terrorism and especially advances in methodological approaches to research it, despite all the events of the last decades, a deep and coherent understanding of the nature, dynamics and outcomes of terrorist threats, acts, campaigns and outcomes is still in a formative stage. The following books are representative of the challenges inherent in seeking to understand the multidimensional aspects of a subject that has been both emotionally and intellectually demanding in recent and contemporary times. Each in their own right utilizes different approaches with varying degrees of success to advance our knowledge of terrorism. They also come from a particular culturally oriented approach to the various social and behavioral sciences, whose constructs are ideally universal but must take into account the different cultural milieus that seek to observe, research, and analyze. Moreover, the application of theory in different environments may be questionable when viewed through the prism of an …
