Libya
In the 1980s Mobutu's principal enemy was Muammar al-Gaddafi. In May 1985, while visiting Burundi, Gaddafi urged Zairians to rise up and "physically eliminate" Mobutu. When the Voice of Zaire and the Kinshasa central post office were bombed in 1984, in both cases the Zairian government blamed the Gaddafi government.
Zaire also militarily supported the government of Chad's Hissein Habré's during that country's civil war. Mobutu's primary fear was that a pro-Gaddafi government would take hold in Chad and threaten Sudan and the Central African Republic, both countries contiguous with Zaire.
Mobutu also enjoyed an amicable relationship with Sudan's Gaafar Nimeiry, who was also an enemy of the Gaddafi government.
