This book seeks to critically review and evaluate the changes and consistencies in how warfare is interpreted and represented by academics, mass media outlets and political actors in the 21st century. The authors suggest that it is essential to understand the evolution and transformation of contemporary warfare's conceptualisation and practice in order to make sense of the current global geopolitical transformations that are in process, from a unipolar to multipolar global order. They therefore examine the various key actors in international relations from conceptual, theoretical and empirical perspectives through thematic chapters that demonstrate the increasingly central role played by intangible factors in the representation and management of contemporary armed conflict. The book stresses the need to reflect and rethink the potentially highly problematic trajectory of the global community within the framework of 21st century warfare's political and informational influence and effects.
