Violent non-state actor

In international relations, violent non-state actors (VNSAs), also known as non-state armed actors or non-state armed groups (NSAGs), are individuals or groups that are wholly or partly independent of governments and which threaten or use violence to achieve their goals. VNSAs vary widely in their goals, size, and methods. They may include narcotics cartels, popular liberation movements, religious and ideological organizations, corporations (e.g. private military contractors), self-defence militia, and paramilitary groups established by state governments to further their interests. While some VNSAs oppose governments, others are allied to them. Some VNSAs are organized as paramilitary groups, adopting methods and structure similar to those of state armed forces. Others may be informally structured and use violence in other ways, such as kidnapping, using improvised explosive devices, or hacking into computer systems. The Geneva-based NGO Centre on Armed Groups is dedicated to better understanding and engaging with armed groups. Non-state actor Thomas, Kiser, and Casebeer asserted in 2005 that "VNSA play a prominent, often destabilizing role in nearly every humanitarian and political crisis faced by the international community". As a new type of actor in international relations, VNSAs represent a departure from the traditional Westphalian sovereignty system of states in two ways: by providing an alternative to state governance; and by challenging the state's monopoly of violence. Phil Williams stated in 2008 that in the 21st century, they "have become a pervasive challenge to nation-states". Williams argues that VNSAs develop out of poor state governance but also contribute to the further undermining of governance by the state. He explains that when weak states are "unable to create or maintain the loyalty and allegiance of their populations", "individuals and groups typically revert to or develop alternative patterns of affiliation". This causes the family, tribe, clan or other group to become "the main reference points for political action, often in opposition to the state".
