Terrorism
Terrorism is, in the broadest sense, the use of intentionally indiscriminate violence as a means to create terror among masses of people; or fear to achieve a religious or political aim. It is used in this regard primarily to refer to violence during peacetime or in war against non-combatants. The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but gained mainstream popularity during the U.S. presidency of Ronald Reagan (1981–89) after the 1983 Beirut barracks bombings and again after the 2001 September 11 attacks and the 2002 Bali bombings.
Critical terrorism studies
There has been a huge amount of academic discussion about the ontological and epistemological foundations of critical terrorism studies. Within CTS, there is a broad agreement on the need to examine terrorism and terrorists from a historical, contextualized perspective asking 'how' questions of causation and constitution, rather than the more orthodox problem solving questions of a single isolated event. For instance, CTS questions why a terrorist action happens, asking whether the terrorists simply hate western notions of freedom, or whether they have deeper underlying political motivations? CTS adopts the ontological position that "terrorism" is fundamentally a social fact rather than brute fact.
