IntroductionCounterinsurgency (COIN) operations necessitate a multifaceted approach that considers political, economic, developmental, and security factors in order to achieve long-term peace and security. Despite this recognition, critical aspects are frequently overlooked, particularly in the context of combating jihadist groups such as Boko Haram in West Africa. This paper investigates the 3Ds (Development, Diplomacy, and Defense) approach to COIN, assessing its effectiveness in COIN efforts and post-war reconstruction in Nigeria and drawing lessons from experiences in Uruzgan province, Afghanistan.MethodIn the qualitative study, the 3Ds serve as a conceptual framework for analyzing the fundamental aspects of COIN in existing literature, with a focus on their relevance in West Africa. It incorporates insights from Afghanistan's Uruzgan province to help inform the study of the 3Ds approach in COIN efforts and post-war reconstruction. Interactions with key stakeholders and counterinsurgency experts provide firsthand information.ResultsThe analysis emphasizes the importance of a comprehensive COIN strategy that includes significant governance and political reforms to address historical disparities and ideological motivations of jihadist groups. COIN entails a variety of measures, including political, administrative, military, economic, psychological, and informational strategies, that are used in tandem to achieve stability and transformation. The 3Ds approach is seen as a template for harmonizing these aspects, particularly in dealing with existing insurgencies and preventing future ones in the region.DiscussionGiven the region's underlying human insecurity, the study focuses on how the 3Ds framework can effectively address existing insurgencies and prevent future ones. It emphasizes the importance of carefully implementing and adapting the 3Ds approach to the unique dynamics and challenges of West Africa. Furthermore, the study emphasizes the importance of a balanced and integrated approach to COIN that considers the interplay of security, development, and diplomacy in order to ensure long-term stability and security in the region.
