NAMIBIA-ANGOLA. SHIFTING ALLIANCES. 1974-6
The fall of the Caetano regime in Portugal in April 1974 and the rapid decolonization of Mozambique and Angola, had a decisive impact on both the regional politics of liberation and Pretoria's attempts to maintain - in the absence of Portugal's help - South Africa's domination of the region. In particular, the shift of the liberation movements' 'frontline' to the borders of South Africa and Namibia, shook the very foundations of South Africa's regional policies embedded in the concept of buffer states, which now had to be reformulated.
