The Impact of the Theory of Liberalism on the United Nations’ and African Union’s Approach to Global Peace and Security

This article presents a critical analysis of the impact (influence) of the theory of liberalism on the United Nations’ (UN) and Africa Union’s (AU) approach to global peace and security. There are various and sometimes conflicting theories of international relations relating to how world politics functions, including international and regional peace and security. Which theory of international relations and peace would explain the United Nations' role in promoting worldwide peace and security, as well as the African Union's role in promoting regional peace and security within the African continent? Even though this question is difficult to answer and no single theory can fully capture the complexities surrounding the issues at hand, this article contends that the liberal peace framework has had a profound influence on the creation of the United Nations and the African Union, as well as their roles in international and regional peace and security. To this purpose, the study adopts a qualitative critical research strategy with secondary data collection and analytical approaches which comprise characterizing, thematizing, and contextualizing the topic at hand. The paper explains how liberalism influenced the essential thinking, values and norms, institutional legitimacy and mandate. It also conceptualizes and operationalizes peace and security concerns at the UN and AU. This is tied to UN-led global action which, when paired with the AU's considerable continental role, illustrates liberalism's impact in terms of laws, conventions, principles, and practices, facilitating cooperative peacebuilding efforts. Despite some critical theoretical and practical shortcomings, this paper argues that liberalism is still essential to achieving the UN’s and AU's, agenda for global peace and security.
