It would be like Rhodesia in SA too, thankfully Mandela was very smart man.
As for Rhodesia, this country had probably best military units in humankind history. Rhodesian SAS and Selous scouts. Scouts especially were very effective, because of locals with bush knowledge (both white and black people), ZANLA and ZIPRA hunted their members (especially black members as "traitors") even after they got whole country.
