This document discusses non-state actors (NSAs), which are organizations that participate in international relations without being part of a state. NSAs include NGOs, multinational corporations, religious groups, and more. Their increasing role in global affairs challenges the traditional Westphalian concept of states as the sole actors in international politics. NSAs can influence public opinion and work with international organizations on issues like human rights. Their activities add complexity to conflicts that involve multiple non-state armed groups.
