So what, exactly, is your point? Are you saying that what the Apartheid government did was legal and legitimate? Obviously bombing civilians is wrong, nobody disputes that. But the Apartheid government killed and tortured many innocent people. Both sides did bad things. None of this is news. Why are you pointing this out?

Edit: the thing that makes Mandela special is that, once he became the government, it would have been just as "legitimate" for him to have behaved as the Apartheid government had, but he effected peace instead.
