Despite taking the necessary countermeasures on the battlefield, the South African government discerned it had reached the political limits of further escalation in Angola. The casualties sustained during the Cuito Cuanavale campaign had been sufficient to cause public alarm and provoke difficult questions about the tactical situation on the border and why South African soldiers were dying there. There was little reason to believe yet another bloody campaign would be successful in expelling the Soviets and Cuba from the region; on the contrary, as in the past, it could lead to an increase in the amount of Soviet weapons and Cuban troops. The conflict had also evolved from a low-intensity struggle against lightly armed insurgents into protracted battles between armies backed by all the paraphernalia of modern conventional warfare, with the accompanying rise in human and material costs. This contributed to a sense of war weariness and increased the growing skepticism and sensitivity in civilian circles toward the SADF's Angolan operations.
