This book explores the possible (actual, potential and imagined) future security threats migration from Nigeria could pose to Europe, the United States of America, Canada and to some extent Australia. The negative consequences of terrorism, resource curse, extreme poverty, bad governance and illiteracy are highly likely to compound the already existing migration (both legal and illegal migration) from Nigeria to Europe. Given the current nationalist and populist tendencies in the United States of America and many parts of Europe, which have amplified the securitization of migration, the authors argue that the continuous high influx of legal and illegal migrants from Africa is a potential global security case.
