An integral part of defining terrorism has been to separate out different types of terrorism, based on what kinds of attack agents they use (biological, for example) or what its perpetrators seek to defend (as in ecoterrorism). Here, a comprehensive list of types of terrorism, with links to more information, examples and definitions.
Defining Terrorism
Terrorism is distinguished from other acts of violence, and from war, by always having these four characteristics:
Terrorists violate the rules of modern warfare, established in acts called the Geneva Conventions and Hague Conventions; or they are actors (e.g., sub-state groups) who can't declare war legitimately;
Its goal is to achieve political change
Its targets are symbolic of the political issue in question
Acts of terror are designed to get attention from the public and media
There is no official definition of terrorism agreed on throughout the world, and definitions tend to rely heavily on who is doing the defining and for what purpose. Some definitions focus on terrorist tactics to define the term, while others focus on the actor. Yet others look at the context and ask if it is military or not.
We will probably never arrive at a perfect definition to which we can all agree, although it does have characteristics to which we all point, like violence or its threat.
Bioterrorism refers to the intentional release of toxic biological agents to harm and terrorize civilians, in the name of a political or other cause.The U.S. Center for Disease Control has classified the viruses, bacteria and toxins that could be used in an attack. Category A Biological Diseases are those most likely to do the most damage. They include:
Anthrax (Bacillus anthracis)
Botulism (Clostridium botulinum toxin)
The Plague (Yersinia pestis)
Smallpox (Variola major)
Tularemia (Francisella tularensis)
Hemorrahagic fever, due to Ebola Virus or Marburg Virus
Cyberterrorism
Cyberterrorists use information technology to attack civilians and draw attention to their cause. This may mean that they use information technology, such as computer systems or telecommunications, as a tool to orchestrate a traditional attack. More often, cyberterrorism refers to an attack on information technology itself in a way that would radically disrupt networked services. For example, cyberterrorists could disable networked emergency systems or hack into networks housing critical financial information. There is wide disagreement over the extent of the existing threat by cyberterrorists.
Ecoterrorism is a recently coined term describing violence in the interests of environmentalism. In general, environmental extremists sabotage property to inflict economic damage on industries or actors they see as harming animals or the natural enviroment. Thes have included fur companies, logging companies and animal research laboratories, for example.
"Nuclear terrorism" refers to a number of different ways nuclear materials might be exploited as a terrorist tactic. These include attacking nuclear facilities, purchasing nuclear weapons, or building nuclear weapons or otherwise finding ways to disperse radioactive materials.
Narcoterrorism
Narcoterrorism has had several meanings since its coining in 1983. It once denoted violence used by drug traffickers to influence governments or prevent government efforts to stop the drug trade. In the last several years, narcoterrorism has been used to indicate situations in which terrorist groups use drug trafficking to fund their other operations.
