After the indecisive results of the Battle of Cuito Cuanavale, Fidel Castro claimed that the increased cost of continuing to fight for South Africa had placed Cuba in its most aggressive combat position of the war, arguing that he was preparing to leave Angola with his opponents on the defensive. According to Cuba, the political, economical and technical cost to South Africa of maintaining its presence in Angola proved too much. Conversely, the South Africans believe that they indicated their resolve to the superpowers by preparing a nuclear test that ultimately forced the Cubans into a settlement.
