Shalev, as a South African academic I can assure you that your reading of the South African situation is wrong. True, many white South Africans' reaction to BDS was to rally behind the regime and even shift to the far right Conservative Party; but the regime itself began making concessions already in the 1970s in the face of industrial and township protest, sporting isolation and the arms embargo. It did not cease offering 'reforms' as BDS pressure intensified in the mid 1980s but on the contrary accelerated them - for example, dismantling the hated pass laws and racial job reservations. Along with popular unrest and economic stagnation, BDS played a crucial role in persuading elements of the ruling elite to seek talks with the ANC.
