This book offers a comprehensive, highly informative and interdisciplinary study on territorial integrity and the challenges globalization, self-determination and external interventions present. This study aims at not only to fill an epistemological gap in this regard, but also answer the question of whether International Law is adequately equipped to help states address these challenges. The author argues that the biggest threat that many states are confronted with today is their disintegration rather than their obsolescence, and that International Law has not often been able to prevent that eventuality. In fact, states, when they were not destroyed by war, managed to survive, thanks to the flexibility of territoriality, i.e. their ability to adjust to difficult situations as they arose.
