I would think that PM Netanyahu is a capable of being an intelligent statesman, like former PM Ben Gurion, and make a right and responsible decision for Israel, by agreeing to the Quartet's and PA's peace proposals at this juncture. The urgency of diplomatic talks between Israel and the PA should dominate the region and not necessarily Iran. My understanding since he took premiership is that he intended to make these decisive moves towards peace in any case despite the obstacles.
