`a study that is highly impressive in its comprehensiveness and depth of analysis. It is this balanced approach and detail of analysis that make this study so valuable and that will undoubtedly establish it as the essential starting point for any further attempts to define terrorism in international law.' Human Rights Law Review (2007) `This book is immediately recognizable for its thoroughness in research and meticulousness in detail. the usefulness of the book in the overall development of a coherent legal framework for fighting terrorism is assured.' Chinese Journal of International Law (2007) `Ben Saul's book is an exceptional study of the issue. Despite the fact that many scholars have written extensively on terrorism, this book is exemplary of fine scholarship and deserves a wide readership. Saul's book is erudite, clear, and informative without being turgid. The author makes interesting and stimulating points, thus opening up the reader's horizons to further reflect on the issue. The arguments employed are strengthened by extensive empirical research. Given the persistent disagreement about defining terrorism over many years this book is highly educative.' European Law Journal (2008) `He deftly addresses one of the trickiest issues in defining terrorism - how to treat asymmetric warfare in self-determination movements. It is quite thorough in its detail making the monograph useful as a reference text. Throughout the monograph, Saul maintains an even-handed tone - even when discussing potentially inflammatory matters such as the Israeli-Palestinian conflict. Saul's monograph lays out a strong case for addressing terrorism on the international level as a crime and presents a coherent framework for doing so. a good start toward making international law relevant to post-9/11 terrorism.' American Journal of International Law (2007) `One can recommend this book to everyone interested in the problematic of terrorism.' Panstwo I Prawo (Poland) (2008) `the book provides a sophisticated study of the definition of terrorism in international law. It is a comprehensive and important contribution to the existing literature.' Irish Yearbook of International Law (2006)
