This study has been undertaken as the first ever joint research publication between defence institutions in Denmark and Pakistan. Given the development in international security politics in the last few years, it is fair to argue that both Denmark and Pakistan are at a point where future security challenges require a development of policies and strategies. Though the roles of Denmark and Pakistan respectively are different in nature, a lot of commonalities in conceptual thoughts and actions were found between the two countries at all levels. The book at hand gathers a number of lessons identified from Afghanistan and Pakistan with the objective of promoting sustainable regional peace building and developing military and civilian cooperation strategies for counterinsurgency and counterterrorism.
