Phil- respectfully, I disagree with your assesment of the audience for Mamdani’s speech, while I agree that it is a very important intervention.
First of all, I think that anti-Zionist Jews outside of historical Palestine, by definition, have to reject the Zionist assumption that as Jews they will have any stake in a future non-Zionist Palestine necessarily. While the role of anti- or non-Zionist Jews as allies in solidarity with a liberation struggle is crucial, and while they certainly may have opinions as to what visions of society they would like to see, they are not stakeholders in the future community.
Secondly, I think the anti-Zionist Jews of contemporary Israel probably already agree largely with Mamdani’s points and probably are working as hard as they can to convince their society.
I do think that there is a need for more loud, clear Palestinian voices making this vision heard. The BDS call is not the Freedom Charter. It is the basic minimum standards of solidarity. While it is grounded in basic principles of equality under the law and human rights for all, it is a tool of struggle, not a positive framework for a future society. The One State Group offers such a vision, but I don’t think it can be said to be broadly representative of opinion or legitimacy in Palestinian society either within Palestine or without.
There is not, as far as I know, a political group or party equivalent to the ANC within the Palestinian context, and I think there desperately needs to be.
