Why Should we Worry about Nigeria's Fragile Security?

Abstract This paper explores the multifaceted implications of Nigeria's persistent security crisis, highlighting its domestic, regional and global consequences. It examines the humanitarian toll, economic disruption, poverty, food insecurity and the erosion of social cohesion within Nigeria. Regionally, it analyses how Nigeria's instability exacerbates insecurity across West Africa and weakens collective peacebuilding efforts. Internationally, it underscores the implications for energy security, irregular migration and European border stability. Drawing on verified data and scholarly literature, this article argues that stabilising Nigeria is vital for its survival, regional peace and international order in an increasingly interconnected world.
