Can the emerging concept of "planetary politics" reshape the traditional nation-state system?

The growing threat of global challenges such as climate change, pandemics, and transnational economic systems has led to discussions about "planetary politics"—a framework that emphasizes global cooperation over national sovereignty. This concept challenges the conventional nation-state order which has historically prioritized individual national interests. Proponents argue that the interconnectedness of modern crises necessitates a shift towards collaborative governance models that transcend borders. Critics, however, warn that such an approach might undermine national autonomy and democratic accountability. This question explores how practical and impactful planetary politics could be in addressing the complexities of 21st-century global governance.
