Israeli arms to South Africa

This was in my Top Stories section for May 24, 2010:

Haaretz (Israel): Report: Israel offered to sell nuclear weapons to apartheid South Africa - well, I certainly was not expecting this headline on the front page. This article quotes an article from The Guardian (UK) about a new book from an American researcher who found documents on nuclear talks between Israel and South Africa in the 1970s. Apparently a nuclear deal didn't quite go through, but Israel did sell tritium to SA and there may have been a joint nuclear test in late 1979.

There have been a few updates. According to the Daily Beast, Shimon Peres has denied a lot of the scandal, and called it slander. And Haaretz has a refutation of that by the author of the book, Sasha Polakow-Suransky.
