No one definition of terrorism has gained universal acceptance. For the purposes of this report, however, we have chosen the definition of terrorism contained in Title 22 of the United States Code, Section 2656f(d). That statute contains the following definitions:
The US Government has employed this definition of terrorism for statistical and analytical purposes since 1983.
Domestic terrorism is probably a more widespread phenomenon than international terrorism. Because international terrorism has a direct impact on US interests, it is the primary focus of this report. However, the report also describes, but does not provide statistics on, significant developments in domestic terrorism.
* For purposes of this definition, the term “noncombatant” is interpreted to include, in addition to civilians, military personnel who at the time of the incident are unarmed or not on duty. For example, in past reports we have listed as terrorist incidents the murders of the following US military personnel: Col. James Rowe, killed in Manila in April 1989; Capt. William Nordeen, US defense attache killed in Athens in June 1988; the two servicemen killed in the Labelle discotheque bombing in West Berlin in April 1986; and the four off-duty US Embassy Marine guards killed in a cafe in El Salvador in June 1985. We also consider as acts of terrorism attacks on military installations or on armed military personnel when a state of military hostilities does not exist at the site, such as bombings against US bases in Europe, the Philippines, or elsewhere.
