It should be clear from what the PA says publicly and does that is not a peace partner for Israel. When Israel should do now is laid down their maximum demands and say that if the Palestinians authority wants to stay this is what Israel must receive in order for the state to exist. Israel should say negotiations are fruitless as long as one of the parties tries a deliberate and run. Whenever, Israel accommodates the Palestinians see this as a sign of weakness and demand more. As an observer from within the Arab camp and from the vantage point of the US White House and State Department this is the reality. No amount of Israeli leftist yearning will change these facts.
