If it suits the PM he will hide behind the cabinet's possible pressure and the prospect of "my coalition will collapse." The end result is we do nothing or just play along for sake of talks like Shamir said he was prepared to negotiate for ten years. On the other hand he has an opportunity to become a statesman, tell it like it is, break the deadlock, come back to his cabinet and say here is the deal: Those who approve, please remain seated, those who oppose I have your replacement waiting outside. Perhaps Natanyahu avoided that cabinet meeting prior to departure for the summit, simply because he did not want to lock himself in with declarations, beyond what he has already stipulated, to draw supporters.
