This study examines the effects of the proliferation of SALWs on the security of the Nigerian state. Although this issue has seldom been tackled in regular or academic literature, it reflects the author"s keen awareness that, in an era of globalization, migrants have been identified as important agents in the proliferation of SALWs into third-world countries. The paper seeks to provide an insight into the socio-economic and political variables operating in the source and destination of such movements, with particular emphasis on migrants and arms proliferation. The study uses the qualitative approach for data analysis, it relies on upon, data gathered through secondary sources, and is reinforced with the argument on the liberal theoretical framework of analysis. The paper concludes that, while weapons play a significant role in intensifying conflict that exerts enormous human and economic costs, the causes of such conflicts lie in political, economic, ethnic, and religious differences and disparities. Finally, the paper looks at the appropriateness of examining the full implications of SALWs as a border management theme and the role of complementary measures for facilitating border control.
