And it's not just Tutu, either. It's also some of the same members of the Jewish community in South Africa who opposed apartheid there who are making that comparison:

FOR YEARS, critics have compared Israeli policies in the occupied territories to the old South African apartheid system. Now more mainstream figures � such as Zbigniew Brzezinski, the Canadian-born former U.S. National Security Adviser, and South African anti-apartheid stalwarts Bishop Desmond Tutu and author Breyten Breytenbach � are drawing the parallel. Members of the 80,000-strong Jewish community in South Africa have joined the debate as well.

Not In My Name, a declaration written by two leading Jewish anti-apartheid activists, Ronnie Kasrils and Max Ozinksi, and signed by 220 Jews, acknowledges Israeli security concerns but, as reported in The Guardian newspaper, adds:

"It becomes difficult, from a South African perspective, not to draw parallels with the oppression expressed by Palestinians under the hand of Israel and the oppression experienced in South Africa under apartheid rule."
