In October 1985 eight Israeli F-15 Eagles carried out Operation Wooden Leg intending to bomb the PLO's new headquarters in Tunis, Tunisia, more than 2,000 km from Israel. The attack cost 270 lives, most of them Tunisian civilians. The attack was later condemned by the United Nations Security Council. The United States is thought to have assisted or known of the attack. The Iran–Iraq War took place from 1980 to 1988. Iraq was accused of using illegal chemical weapons to kill Iranian forces and against its own dissident Kurdish populations. Both sides suffered enormous casualties, but the poorly equipped Iranian armies suffered worse for it, being forced to use soldiers as young as 15 in human-wave attacks. Iran finally agreed to an armistice in 1988.

Battle of Cuito Cuanavale took place as part of the Angolan civil war and South African Border War from 1987 to 1988.
