First off the Palestinians are many factions with political loyalties and command structures in often opposing and conflicting foreign sectarian governments that have no desire for the Palestinian people to ever make peace with Israel. This plays out on the ground in violent skirmishes and power struggles between the Palestinian factions, with no central command structure to coalesce authority, disrupting any one faction's attempts at peace negotiations. The PA more often than not play to the hand of these foreign based factions, fearing for credibility and also their lives. Second, the Palestinian agenda if at any point unified between the foreign Muslim controllers, is a proxy pawn strategy to enforce a bigoted view of the Middle East as belonging to only Muslim governments. Lastly, do you really know who you are negotiating with if the final decisions are determined by non-Palestinians Muslims who consider any contract with a non-Muslim non-binding.
