Many of Africa's emerging security threats are transnational, including issues such as migration, disease, conflict, and environmental degradation. Most of these problems are often well outside of the scope of any one individual developing nation to resolve. In light of the UK's decision to leave the European Union (EU) and the significant security concerns evolving within West Africa, this thesis will argue why a strategic shift in the UK's approach is required. This thesis will also argue that a shift towards West Africa (particularly Nigeria, Ghana and Sierra Leone) will help the UK to; build reliable partners, strengthen the UK's own internal security, prevent the proliferation of failing states, and support UK National Security Objectives. This in turn will achieve the UK's overall intent of being a truly 'Global Britain'.
