State terrorism
While the most common modern usage of the word terrorism refers to civilian-victimising political violence by insurgents or conspirators, several scholars make a broader interpretation of the nature of terrorism that encompasses the concepts of state terrorism and state-sponsored terrorism. Michael Stohl argues, "The use of terror tactics is common in international relations and the state has been and remains a more likely employer of terrorism within the international system than insurgents. Stohl clarifies, however, that "[n]ot all acts of state violence are terrorism. It is important to understand that in terrorism the violence threatened or perpetrated, has purposes broader than simple physical harm to a victim. The audience of the act or threat of violence is more important than the immediate victim."
Political violence
While there lacks a concrete definition of terrorism, the United States Department of Defense however defines terrorism as, "the calculated use of unlawful violence or threat of unlawful violence to inculcate fear; intended to coerce or to intimidate governments or societies in the pursuit of goals that are generally political, religious, or ideological." What is and is not considered terrorism is itself a controversial political question, as states have often used the label of terrorism to exclusively demonize the actions of their enemies while obscuring "legal" violence administered by the state (e.g. The Troubles, CPP–NPA–NDF rebellion, 2014 Israel–Gaza conflict).
