The term "realism" in international relations theory emphasizes power dynamics and national interests as primary motivators of state behavior. Realists argue that states operate in an anarchic system where survival and security are paramount. Power is considered a zero-sum game; thus, cooperation is often viewed with skepticism. This perspective underscores the inevitability of conflict and competition in international politics. Realism shapes foreign policy decisions, focusing on pragmatic approaches rather than idealistic pursuits, such as enhancing national security or territorial integrity.
