Israel demanded a certain recognition which was technically feasible but politically suicidal, from Abbas/Pals. Pals demand a border designation which is equally technically feasible but politically suicidal from Bibi/Israel. There's an appropriate symmetry, and it shows cleverness by Palestinians to avoid being blamed for alone roadblocking negotiations. Your four items are beyond the capability of Palestinians to deliver, so they neither suggest a way forward nor spotlight who is the reluctant peacemaker. So what's the point? Just saying it is all wishful thinking and the recognitions and borders arguments just highlight the futility of the process and how far they are from substantive deliberations?
