Realist theory

Realist theory, primarily in international relations, asserts that nations act in their interests to gain power and security in a competitive world. It emphasizes the anarchic nature of the global system, where no central authority exists to enforce rules. Realists believe that human behavior is driven by self-interest and that conflicts among nations are inevitable. The focus is on military strength, political influence, and strategic alliances, considering moral or ethical concerns secondary to survival and advantage. Essentially, realism provides a pragmatic lens for understanding political behavior on the global stage.
