Mokhiber explains that the Oslo Accords, poisoned from the start by US posing as a neutral 'mediator' in them, undermined the decolonial approach to the Palestine question not only in public discourse but within the UN. He distinguishes the UN's failure in Palestine to its support of a decolonial movement in the effort to end apartheid in South Africa. A lifelong (31 years at the UN) specialist in international human rights law, he casually refers at one point to double standards at the ICC and says he has largely given up hope in official institutions, including the UN in many capacities (he notes the value of aid work organized by the UN).
To many, the contents of this interview (and of Mokhiber's letter) are not new. But it covers its subjects well, and Mokhiber's voice here is one that might be credible to some who are otherwise not inclined to hear anything. Worth a watch, imo.
