In the end, I believe the negotiations did not fail because the gaps were too wide, but because the level of trust was too low. Both sides were concerned that any concessions would not be reciprocated and would come at too great a political cost. And the deep public skepticism only made it more difficult for them to be able to take risks.
That line is important for multiple reasons. First, it underscores that the belief gap between the Israeli and Palestinian leadership today is so wide that even if they agree completely on all of the final status issues—borders, Jerusalem, refugees, security arrangements—they are incapable of making a deal.
The leaders on both sides will never take the necessary risks for an agreement without overwhelming public support. That is, while public trust and support may not be a sufficient condition for a just and lasting peace, it is a necessary one. more> https://goo.gl/bJNfc7
