Secret South African documents reveal that Israel offered to sell nuclear warheads to the apartheid regime, providing the first official documentary evidence of the state's possession of nuclear weapons. The "top secret" minutes of meetings between senior officials from the two countries in 1975 show that South Africa's defence minister, PW Botha, asked for the warheads and Shimon Peres, then Israel's defence minister and now its president, responded by offering them "in three sizes". The two men also signed a broad-ranging agreement governing military ties between the two countries that included a clause declaring that "the very existence of this agreement" was to remain secret.

ABC News: Israel 'tried to sell nuclear weapons': If Obama & Co. were serious about a sustained process of nuclear diminution, an early part of that process has to be an Israel that comes out of the closet, and in the process of doing that, says yes, we've got the bomb.
The Guardian: Israel and apartheid: a marriage of convenience and military might: For years after its birth, Israel was publicly critical of apartheid and sought to build alliances with the newly independent African states through the 1960s. But after the 1973 Yom Kippur war, African governments increasingly came to look on the Jewish state as another colonialist power. The government in Jerusalem cast around for new allies and found one in Pretoria. For a start, South Africa was already providing the yellowcake essential for building a nuclear weapon. By 1976, the relationship had changed so profoundly that South Africa's prime minister, John Vorster, could not only make a visit to Jerusalem but accompany Israel's two most important leaders, Yitzhak Rabin and Shimon Peres, to the city's Holocaust memorial to mourn the six million Jews murdered by the Nazis. Neither Israeli appears to have been disturbed by the fact that Vorster had been an open supporter of Hitler, a member of South Africa's fascist and violently antisemitic Ossewabrandwag and that he was interned during the war as a Nazi sympathiser. Rabin hailed Vorster as a force for freedom and at a banquet toasted "the ideals shared by Israel and South Africa: the hopes for justice and peaceful coexistence".
