The amended law requires the Department of State to report on the extent to which other countries cooperate with the United States in apprehending, convicting, and punishing terrorists responsible for attacking US citizens or interests. The law also requires that this report describe the extent to which foreign governments are cooperating, or have cooperated during the previous five years, in preventing future acts of terrorism. As permitted in the amended legislation, the Department is submitting such information to Congress in a classified annex to this unclassified report. No one definition of terrorism has gained universal acceptance. The U.S. Government has employed these definitions of terrorism for statistical and analytical purposes since 1983.
Domestic terrorism is 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. Nonetheless, the report also describes, but does not provide statistics on, significant developments in domestic terrorism. U.S. Embassy Marine guards killed in a cafe in El Salvador in June 1985. We also consider as acts of terrorist 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 U.S. bases in Europe, the Philippines, or elsewhere.
