Types of Terrorism

Different types of terrorism have been defined by lawmakers, security professionals and scholars. Types differ according to what kind of attack agents an attacker uses (biological, for example) or by what they are trying to defend (as in ecoterrorism).

Researchers in the United States began to distinguish different types of terrorism in the 1970s, following a decade in which both domestic and international groups flourished. By that point, modern groups had began to use techniques such as hijacking, bombing, diplomatic kidnapping and assassination to assert their demands and, for the first time, they appeared as real threats to Western democracies, in the view of politicians, law makers, law enforcement and researchers. They began to distinguish different types of terrorism as part of the larger effort to understand how to counter and deter it.

 

State Terrorism

Many definitions of terrorism restrict it to acts by non-state actors.

But it can also be argued that states can, and have, been terrorists. States can use force or the threat of force, without declaring war, to terrorize citizens and achieve a political goal. Germany under Nazi rule has been described in this way.

It has also been argued that states participate in international terrorism, often by proxy. The United States considers Iran the most prolific sponsor of terrorism because Iran arms groups, such as Hizballah, that help carry out its foreign policy objectives. The United States has also been called terrorist, for example through its covert sponsorship of Nicaraguan Contras in the 1980s. 

 

Bioterrorism

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

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

“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.

The Many Definitions of Terrorism

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. Indeed, the only defining quality of terrorism may be the fact that it invites argument, since the label “terrorism” or “terrorist” arises when there is disagreement over whether an act of violence is justified (and those who justify it label themselves “revolutionaries” or “freedom fighters,” etc.). So, in one sense, it may be fair to say that terrorism is exactly violence (or the threat of violence) in context where there will be disagreement over the use of that violence.

But this doesn’t mean that no one has tried to define terrorism! In order to prosecute terrorist acts, or distinguish them from war and other violence that is condoned, national and international institutions, as well as others, have sought to define the term. Here are some of the most frequently cited definitions.

League of Nations Convention Definition of Terrorism, 1937

Ethnic separatist violence in the 1930s provoked the League of Nations, formed after World War I to encourage world stability and peace, to define terrorism for the first time, as:

All criminal acts directed against a State and intended or calculated to create a state of terror in the minds of particular persons or a group of persons or the general public.

Terrorism Defined through Multilateral Conventions

The United Nations Office on Drugs and Crime has collated the 12 universal conventions (international agreements) and protocols against terrorism signed since 1963. Although many states have not signed them, all seek to create consensus that certain acts count as terrorism (for example, hijacking a plane), in order to create the means to prosecute them in signatory countries.

U.S. Department of Defense Definition of Terrorism

The Department of Defense Dictionary of Military Terms defines terrorism as:

The calculated use of unlawful violence or threat of unlawful violence to inculcate fear; intended to coerce or to intimidate governments or societies in the pursuit of goals that are generally political, religious, or ideological.
