After a frustrating week of shuttle diplomacy here in which the Obama administration failed to persuade Israelis and Palestinians to renew peace talks, leaders of both sides are heading to the US to make their cases that the administration should push the other harder.

Obama will meet in New York on Tuesday with Prime Minister Benjamin Netanyahu of Israel and Palestinian President Mahmoud Abbas.

Palestinian leaders say the sources of frustration could not be clearer — Israel’s refusal to freeze settlement building in the West Bank and East Jerusalem in keeping with earlier commitments and its insistence on holding peace talks without agreeing to deal with key issues of Jerusalem and Palestinian refugees.

“Without a settlement freeze or an agreement to talk about the core issues, there is no point in starting the negotiations,” Saeb Erekat, the top Palestinian negotiator said. “Ask Netanyahu if he is willing to negotiate on Jerusalem and on refugees. He refuses. And we all know that if he ever accepted, he would lose his governing coalition.” Netanyahu’s coalition is largely right-wing and pro-settlement.

Israeli officials say they will seek to focus American attention away from settlements and on what they consider the real dangers plaguing the region— Iranian nuclear ambition and Palestinian intransigence. Netanyahu said in an interview with Israel’s Channel 10 on Thursday. “It is clear that the fate of those citizens and of the borders will have to be decided. But they can’t be decided until the talks start.”
