Realism: Its Relevance and Need for Renewal
Main Article Content
Abstract
This paper uses the theoretical lens of realism to analyze the events of World War II generally, and the decision to use the bomb specifically to show how realism still finds salience in international relations theorizing. It shows, however, that while realism has a parsimonious and compelling explanation for how the world works, that there are limits to its explanatory and predictive power. Globalization, international cooperation and interdependence, climate change, refugee crises, pandemics and the flows of people and money across borders are all geopolitical features that realism as a theory has no adequate answer for. The world has changed significantly since 1945 and other schools of thought have emerged that also address the dynamics of the international system in which we live. Liberalism, constructivism and feminism are therefore some of the other perspectives that help us better understand international politics. Realist thinkers should therefore take the opportunity to review some of the theory’s main tenets in order to better respond to its limitations.
