By 1989, UNITA held total control of several limited areas, but was able to develop significant guerrilla operations everywhere in Angola, with the exception of the coastal cities and Namibe Province. At the height of his military success, in 1989 and 1990, Savimbi was beginning to launch attacks on government and military targets in and around the country's capital, Luanda. Observers felt that the strategic balance in Angola had shifted and that Savimbi was positioning UNITA for a possible military victory.
