Who's this "we" who dealt with the SA apartheid state?
The international pressure on SA did absolutely nothing to change their mind (I'm old enough to have seen PW Botha's Rubicon speech live on TV). The NP (political party in charge) was slowly and carefully convinced to push out the hardliners.
The people left, like FW De Clerk, actually did the dismantling - unbanned the ANC, released Mandfela from prison, switched to allowing black voters, etc.
The rest of the world's pressure had absolutely no effect on the leadership. Change only came when leadership started changing.
