General Soyster oversaw the Defense intelligence effort in support of the successful U.S. intervention in Panama in 1989 (Operation JUST CAUSE). This operation demonstrated the benefits of increased cooperation and planning that had been achieved between DIA and operational force planners, especially when compared to the 1983 Grenada incursion (Operation URGENT FURY). The Agency provided threat data on "hot spots" throughout the Middle East, Africa, and Asia, and weighed the impact of changes in the Soviet Union, Eastern Europe, and to a lesser degree, Asia, on the rest of world. It supplied decision makers with intelligence support concerning the final Soviet withdrawal from Afghanistan, events surrounding the downing of two Libyan jets, the civil war in Liberia, the Flight 103 investigation at Lockerbie, Scotland, and the Tiananmen Square incident in China. Weapons acquisition issues, counternarcotics, counterterrorism remained a high priority throughout the Defense Intelligence Community.
