You can actually say the South African ones are worse. They turned over the whole country. The Oslo criminals gave up part of Israel in stages.
I remember hearing a recording of Arafat speaking in South Africa saying what Oslo was all about (destroying Israel in stages).
Of course from a Jewish perspective, the Oslo criminals are worse because they gave land away to Arabs who have no legitimate claim on the Land of Israel at all. At least with South Africa, you can say that the blacks were the natives. But there should be separate autonomous white areas. Either that or there should be a breakaway area of South Africa for a free independent white state.
