Roberto established a political alliance with Zairian President Mobutu Sese Seko by divorcing his wife and marrying a woman from Mobutu's wife's village. Roberto visited Israel and received aid from the Israeli government from 1963 to 1969. Romania was the first state to sign agreements with the MPLA. In May 1974, Nicolae Ceaușescu reaffirmed Romania's support for Angolan independence. As late as September 1975, Bucharest publicly supported all three Angolan liberation movements (FNLA, MPLA and UNITA). The MPLA held a party congress in Leopoldville in 1962, during which, Viriato da Cruzfound to be slow, negligent, and adverse to planningwas replaced by Agostinho Neto.

UNITA had its main base in distant south-eastern Angolan provinces, where the Portuguese and FNLA influence were for all practical purposes very low, and where there was no guerrilla war at all. UNITA was from the beginning far better organized and disciplined than either the MPLA or the FNLA. Its fighters also showed a much better understanding of guerrilla operations. They were especially
