Any man that can be imprisoned for 27 years and take the turn the other cheek attitude on release is a bigger man than I!, if not for him, at the end of apartheid ther would have been civil war, and white South Africans would have been slaughtered, he embraced both sides, brought them together and built the foundations for what is South Africa today!.
He also played a part in the Northern Ireland peace process, Blair has gone on record saying so, he encouraged and guided, and took a massive interest!, read his words on the pace wall in Belfast!.
For that I personally feel gratitude, whatever he was imprisoned for, he spent the rest of his life fighting for what is right!, and please don't forget that a lot of the British view was deluded because thatcher the old witch had a real grudge about him while she played footsie with war mongers such as Pinochet.
Old man rest in peace, you really did do your duty!
