There is no disputing fact that terrorism has increasingly become widespread criminal violence as actors in different countries across the globe have their own unique ways of perpetrating the act. In Nigeria which holds a strategic place in the African continent and the global community, democratization process and stability of the country are visibly jeopardized by the high level violence resulting from political, ethnic and religious conflicts as well as organized violent crimes in almost all states of the federation. There are different facilitations of insecurity in Nigeria, among which are porous borders, social inequality, poverty, joblessness and widespread availability of illegal arms and light weapons. This paper tries to highlight some measures to be put in place to combat violent conflicts and terrorism in Nigeria. An understanding of all these issues and other complex dimensions of the Nigerian security environment is imperative for all of us as stakeholders in Nigeria.
