 Some seek to sever the connection between terrorism and violence. Carl Wellman defines terrorism as “the use or attempted use of terror as a means of coercion”. Terrorism is often associated with violence, but that is because violence is a very effective means of intimidation. Yet “violence is not essential to terrorism and, in fact, most acts of terrorism are nonviolent” (Wellman 1979: 250–51). The last claim seems false on any non-circular interpretation. There may be many acts generally considered terrorist that do not involve actual violence, but are meant to intimidate by threatening it; but that is not enough to support the notion of “non-violent terrorism”, which seems odd. So does Wellman’s example of “classroom terrorism”: a professor threatens to fail students who submit their essays after the due date, causes panic in class, and thereby engages in terrorism.
