Here's the NYT Mandela obit.
But you've probably already found that. Here are two items you may also have come across which are worth noting anyway.
First, those of us who were up and moving around during the 1980s recall that the US position on South African Apartheid was a matter of significant controversy. The Reagan Administration strongly opposed the movement to impose sanctions on the South African regime. Mandela and the ANC were placed on the US terror watch list.. not to be removed until 2008.
Second, a long long time ago I remember seeing this cartoon by Tom Toles in some publication. Took me forever to dig it up off the internet.
