The persistent insurgency in Nigeria’s North-East since 2009 has posed a major threat to national security, state authority, and regional stability in West Africa. Despite sustained military campaigns and substantial investment in security operations, Boko Haram and the Islamic State West Africa Province (ISWAP) have retained considerable resilience, adaptability, and operational capability. This study examines the relevance of Sun Tzu’s strategic philosophy to Nigeria’s counterinsurgency doctrine between 2009 and 2025. Employing a qualitative approach based on secondary data, it analyzes how Sun Tzu’s principles of intelligence superiority, strategic deception, adaptability, leadership, psychological warfare, and population-centred operations could strengthen contemporary counterinsurgency efforts. The analysis indicates that, although Nigeria has achieved notable military successes, its excessive reliance on kinetic operations has constrained sustainable strategic outcomes. Integrating Sun Tzu’s strategic principles into counterinsurgency doctrine could improve intelligence effectiveness, operational adaptability, civil–military relations, and strategic communication while promoting a more comprehensive response to insurgent threats. The study concludes that sustainable success against insurgent movements requires a multidimensional strategy that combines appropriately targeted military force with political legitimacy, socioeconomic development, information dominance, and the support of affected communities. By connecting classical strategic thought with Nigeria’s contemporary security challenges, this study contributes a conceptual framework for developing a more adaptive, intelligence-led, and population-centred counterinsurgency doctrine.
