With Nelson Mandela's health looking not so good, I think it is about time to remind everyone that historically while Islamic Iran was strongly supporting the freedom movement there, the US sided with the S African apartheid regime and Reagan in particular was opposed to the sanctions on that government. Israel too was a close cooperator with the racist regime there, and may have even jointly developed a nuclear weapon with S Africa. Israel was the most significant arms supplier to that regime throughout the 1980s and served as a lifeline for the apartheid government during a period when Pretoria faced growing international condemnation and heightened domestic unrest
When Clinton came into office, he tried to get Mandela to oppose Iran -- which Mandela had visited -but Mandella replied that his critics should "go jump in a pool" since "We should not abandon those who helped us in the darkest hour of the history of this country.'
Mandela was already (and continued to be) a vocal critic of Apartheid Zionism in Israel, earning him (and Desmond Tutu) the ire of the pro-Israelis (more) though since then there has been a concerted PR campaign by the pro-Israelis themselves to play down Mandela's opposition.
That's a bit of history that the coming glowing obits of Mandela will no doubt leave out.
