What are the strengths and weaknesses of realism?

Realism, as a theoretical framework in international relations, offers strengths such as its emphasis on the anarchic nature of the international system and the primacy of state interests, which provides a clear lens for understanding power dynamics and conflict. However, its weaknesses include a tendency to overlook the role of non-state actors, international institutions, and the potential for cooperation, which limits its applicability in an increasingly interconnected world. Additionally, realism can be critiqued for its often pessimistic view of human nature and its focus on military power at the expense of economic and soft power considerations.
