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."
Definitions of terrorism
In September 2002, the U.S. national security strategy defined terrorism as "premeditated, politically motivated violence against innocents." This definition did not exclude actions by the United States government and it was qualified some months later with "premeditated, politically motivated violence against noncombatant targets by subnational groups or clandestine agents".
