Chris Hani, the leader of the South African Communist Party and the head of the armed wing of Mandela's ANC organization was assassinated in 1993. His assassination nearly derailed the negotiations to end apartheid, and has had a marked affect on South Africa since.
WI Hani had somehow avoided his assassin or had survived the attack? What changes could we see in South Africa (i.e., he was Mandela's assumed successor)?
