PW Botha succeeded Vorster as prime minister in 1978
Botha was determined to maintain white rule in the face of increasing threats to the regime at home and abroad - called this ‘total onslaught’ and blamed communists (thus helping to get support from the West)
He realised that he would need to make some reforms to apartheid, but also maintain strong and aggressive control
Ironically, extreme white supremacists criticised him for making some concessions to bolster the regime
