Security
Security is freedom from, or resilience against, potential harm (or other unwanted coercive change) from external forces. Beneficiaries (technically referents) of security may be persons and social groups, objects and institutions, ecosystems, and any other entity or phenomenon vulnerable to unwanted change by its environment.
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 financial, political, religious or ideological aim. It is used in this regard primarily to refer to violence against peacetime targets 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 attacks on New York City and Washington, D.C. in September 2001 and on Bali in October 2002.
Violence
Violence is defined by the World Health Organization as "the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, which either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment, or deprivation," although the group acknowledges that the inclusion of "the use of power" in its definition expands on the conventional understanding of the word. This definition involves intentionality with the committing of the act itself, irrespective of the outcome it produces. However, generally, anything that is excited in an injurious or damaging way may be described as violent even if not meant to be violence (by a person and against a person).
Security
No nation can make itself secure by seeking supremacy over all others. We all share responsibility for each other’s security, and only by working to make each other secure can we hope to achieve lasting security for ourselves.
Kofi Annan, Address at the Truman Presidential Museum and Library, Independence, Missouri, USA (11 December 2006)
Violence
I'd hate to be in those [slum] conditions and I'll tell you if I were in those conditions, you'd have more trouble than you have already because I've got enough spark left in me to lead a mighty good revolt.
Hubert Humphrey, speech to the National Association of Counties in New Orleans, Louisiana, July 18, 1966, as reported by The Times-Picayune, New Orleans, July 19, 1966, p. 18.
Violence
The use of violence as an instrument of persuasion is therefore inviting and seems to the discontented to be the only effective protest.
William O. Douglas, Points of Rebellion, p. 78 (1970).
