The Sahel has become a focal point of international security interventions, with external actors providing extensive security force assistance (SFA) to local military, police, and paramilitary forces. Securitizing the Sahel: Analyzing External Interventions and Their Consequences (Oxford UP, 2025) by Dr. Nina Wilen critically examines the rationale, implementation, and consequences of these efforts (2012-2024). With unique access to both military operations and strategy-making in European capitals, the author provides an innovative methodological approach, exclusive material, and a comprehensive perspective. Drawing on extensive fieldwork, including participant observation of military operations and over 100 interviews with policymakers, military personnel, and security practitioners across the Sahel and Europe,this book offers an unprecedented analysis of how SFA has shaped local security dynamics and broader geopolitical competition. The book argues that SFA in the Sahel is driven not just by regional security threats, such as insurgency, violent extremism, and transnational crime, but also by external actors' strategic interests. Through a comparative analysis of bilateral (France, U.S.) and multilateral (EU, UN) initiatives, it demonstrates how SFA has been framed as the primary policy tool to manage instability. Securitizing the Sahel offers both theoretical and empirical contributions to understanding SFA in fragile states. It challenges prevailing frameworks, provides critical insights for policymakers, and highlights the unintended consequences of militarized external assistance in the Sahel and beyond. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.
