I've proved that the US helped the SAs with their nuclear projects You have proved that the USA provided South Africa with a research reactor for open (non-secret) research. You have not proved that South Africa produced an atomic bomb in secret because you are ignorant while claiming knowledge. what have you proved I have proved that the USA didn't know of the secret project to develop an atomic bomb with the production of weapon-grade uranium until they found a test site. I showed that South Africa produced 6 nuclear bombs until they abandoned the project and dismantled the bombs under international verification. --- You are making yourself look silly by claiming knowledge of a secret South African project and of nuclear physics that you are obviously ignorant of.
