“…This approach has often been criticized for being too static and too statist, particularly following the emergence of new non-state actors in the post-Cold War era, including non-governmental organizations (NGOs), intergovernmental organizations (IGOs), and multinational corporations (MNCs). In addition, while "traditional" questions of war and peace continue to dominate much of the diplomatic arena, the international community also faces challenges from "newer" challenges such as terrorism, migration, global warming, and pandemics, which not only defy national boundaries but also require diplomatic cooperation between state and non-state actors (Craig 1983;Puchala 1995;Hocking 2004).
