Which of the following individuals is considered to not align with the principles of realism in international relations?

The individual who does not align with the principles of realism in international relations is Alexander Wendt. He is primarily associated with constructivism, a theory that emphasizes the role of social constructs, identities, and norms in shaping international relations. Constructivism argues that the international system is not defined solely by material power or competition, which are central tenets of realism. Instead, it posits that state behavior and interests are influenced by shared beliefs, culture, and social interactions.

In contrast, thinkers like Thomas Hobbes, John Mearsheimer, and Hans Morgenthau are foundational figures in realism. Hobbes conceptualizes a state of nature characterized by anarchy and a struggle for power, leading to a view of international relations that prioritizes security and survival. Mearsheimer and Morgenthau further develop these ideas, emphasizing the anarchical nature of the international system and the importance of power politics. Thus, Wendt's focus on the social dimensions of international relations sets him apart from the core realist perspective.
