Abstract

With particular focus on Nigeria, this paper examined the security challenges posed to nation – states by “violent non-state actors” such as Boko Harram and Niger Delta Militia. It also studied the linkages between the process of globalization and the rise and expansion of these non-state actors. Findings indicated that core attributes and responsibilities of the state system such as territoriality, monopoly of means of violence and coercion, maintenance of law and order and the protection of lives and property have been challenged in the main by the preponderance of violent groups within the state. Thus, the paper recommended among other things, a thorough understanding of the operational methodologies of all ethnic and regional-based violent groups in Nigeria by national security operatives, a global agreement and cooperation to be reached among nations in various areas in order to bridge socio-economic inequalities which results in aggressive behaviours among the less privileged and reduce global insecurity. It also drew attention to the imperativeness of security sector reforms in Nigeria.
