The major thrust of this study is to assess role of Multi-National Joint Task Force (MNJTF) in the fight against Boko Haram insurgency in Nigeria. The paper relied on primary and secondary sources of data; and adopted Security complex theory, as the theoretical framework. The theory aimed to address the level of security interdependency located between individual units (states), region and the international system as a whole. The data collected were analyzed using content analysis. The study revealed that the presence of the MNJTF has significantly diminished these threats by degrading the capabilities of the sect. The work recommends that theMNJTF should increase its counter-finance capabilities and take immediate action in areas it currently has control over, such as cross-border smuggling and trafficking to limit Boko Haram’s access to funding. Key words: Boko-Haram, Counter-Terrorism, Radicalization, De-radicalization, Multi-National Joint Task Force (MNJTF).
