The National Union for the Total Independence of Angola (UNITA) is the second-largest political party in Angola. Founded in 1966, UNITA fought alongside the Popular Movement for the Liberation of Angola (MPLA) in the Angolan War for Independence (1961–1975) and then against the MPLA in the ensuing civil war (1975–2002).

During the Reagan administration high ranking security officials met with UNITA leaders. The U.S. government encouraged the governments of Israel, Morocco, Saudi Arabia, South Africa, and Zaire to aid UNITA. In 1983 the U.S. and South African governments agreed to ship weapons from the Honduras, Belgium and Switzerland to South Africa and then to UNITA in Angola. The U.S. also traded weapons with South Africa for intelligence on the civil war.
