As a chief negotiator in labor contract bargaining in the U.S. I see a fatal flaw in the idea of a referendum on a peace deal. Negotiators have to be able to deliver a deal, to convince the other side that they can get an agreement approved by those in power. No sane Palestinian leader would commit to the compromises necessary for a deal if it would be subject to an unpredictable referendum process. That's why the Israeli rejectionists want a referendum. There would never be a referendum because there will never be a deal.
