Is realism and balance of power the thing of the past?

Realism and the balance of power remain relevant concepts in contemporary international relations, though their application may evolve in response to new global dynamics. While traditional state-centric power politics continue to play a role, factors like globalization, transnational threats, and non-state actors have complicated the landscape. Emerging multipolarity and regional conflicts also suggest that while the framework of realism is not obsolete, it must adapt to encompass a broader range of influences and interactions in today's world.
