http://www.wordiq.com/definition/TerrorismTerrorism is a tactic of violence that targets civilians, with the objective of forcing an enemy to favorable terms, by
creating fear, demoralization, or political discord in the attacked population.
"Terrorism" is a pejorative characterisation of an enemy's attacks as conforming to an immoral philosophy of violence, in a manner outside of warfare, or prohibited in the laws of war.
The use of the term terrorism or terrorist is politically weighted, as it (and historically, other terms like it) is often used in propaganda used to drum up support in opposition to "terrorists."A nation that supports forms of organized violence (particularly where citizens are affected) tends to dissociate itself from the term, by using neutral or even positive terms to characterize its combatants – such as soldiers or freedom fighters – both of which can be ambiguous terms for describing terrorist actors. However, it is important to note that terrorism is a means, and freedom is a goal. In that sense therefore, the famous saying "One man's terrorist is another man's freedom fighter." is a false dichotomy, since it is actually the methods that are thought of as terrorism, not the goals. It is thus possible to condemn terrorist actions while holding other opinions about the goals of a terrorist.
