Néo-realism

Néo-realism, or Neo-realism, is a theory in international relations that emphasizes the importance of a country's structure—mainly its military and economic power—in shaping its behavior in the global system. It argues that the international arena is an anarchic environment without a central authority, so nations prioritize their own security and interests. Neo-realism focuses on how the distribution of power among states influences their actions and stability, suggesting that international cooperation is limited unless it aligns with their self-interest. It provides a pragmatic lens to understand global politics through power dynamics rather than moral or ideological considerations.
