While there were 6-percent fewer terrorist incidents in 1985, there were more casualties in 1986. Victims or targets included citizens or property of 87 countries, with the Middle East constituting the highest threat area. The problem is complicated by nations employing or supporting terrorists, who receive such advantages as legitimate travel and identification documents. Counterterrorism strategy depends on cooperation with allies and imposition of diplomatic, economic and military burdens on states that sponsor terrorism. The office of the Ambassador at Large for Counterterrorism provides assistance to other countries, and coordinates research and development through the Technical Support Working Group of the Interdepartmental Group on Terrorism. Counterterrorism efforts are showing positive results.
