Despite Nigeria’s critical position in African security, academics and policymakers globally often overlook the gravity of its security challenges. This book examines Nigeria’s survival and its implications on international security. It uses the Nigerian case to contribute to a broader understanding of how great powers relate with small powers, such as most African states. The Nigerian case contributes to the body of literature that integrates small/minor powers into realist studies in International Relations. The empirical and theoretical contributions offer insights for developing more effective policies to address the security challenges outlined in the book.
