With U.S. Vice President Joe Biden in Israel and indirect "proximity" talks with the PA on tap, Prime Minister Netanyahu faces warnings from within his party not to cede Israel’s vital interests.
Edelstein: PA Square to be Named for Mass Murderer
Cabinet Minister Yuli Edelstein has alerted Netanyahu to the fact that “those who are coming to the proximity [diplomatic] talks that are being drawn up these days are far from us and from every human ethical norm." Edelstein says that this coming Thursday, a top-level festive PA ceremony will be held in Ramallah to name a city square after a female terrorist who took part in the Coastal Road Massacre of 37 Israelis, including many children, in 1978. 
US has apparently accepted Israeli position that Olmert's concessions are not binding. 
Edelstein, of the Prime Minister’s Likud party, wrote to Netanyahu that several weeks ago, when news of the above first became known, “we spoke about this, and you responded appropriately, including in the media. The Foreign Minister even submitted an official protest to the U.S. against Abu Mazen [PA chairman Mahmoud Abbas], who is proud of this event... I request that you take firm action to thwart this event.”
Danon: Don't Give in to Pressure
MK Danny Danon, also of the Likud, wished to warn Netanyahu of the pitfalls of the Biden visit. “Biden wants Netanyahu to speak about Jerusalem, the refugees, and the like. The Prime Minister must tell him that he was elected on a clear platform, and that he has no mandate to discuss Jerusalem or to compromise on a Palestinian state, and certainly not on the matter on the return of Arab refugees.”
Danon expressed confidence that Netanyahu would not only remain firm in the face of American pressure, but that he will also resume Jewish construction in Judea and Samaria at the end of the ten-month freeze. The freeze is set to end in late September.
US Accepts Israeli Position: Previous Concessions not Binding
Meanwhile, Haaretz newspaper reports that the indirect talks scheduled to begin soon will not start from where negotiations with the Olmert government left off. Olmert had offered the PA an offer that included major concessions: 94% of Judea and Samaria for a PA state, the entry of 5,000 Arab refugees, and international governance for the holy sites in the Old City. Abbas never responded to this offer, which is far beyond what polls show the Israeli public is willing to accept, but demanded that the resumed talks be based on Olmert’s offer as a “starting point.”
The United States has apparently accepted the Israeli position that whatever was not signed and agree to is not binding in any form.
