While terrorists are almost always marginal in relation to the larger communities and traditions from which they come, they also frequently articulate widespread grievances and feelings present within these communities.
The United Nations Panel on Threats, Challenges, and Change defined terrorism as an action "that is intended to cause death or serious bodily harm to civilians or non-combatants, when the purpose of such an act, by its nature or context, is to intimidate a population or compel a government or international organization to do or abstain from doing any act" (United Nations, 2004, p. 52).
