This is exactly the position put forward by Sharonsksy: that the conflict never was an isolated case of Palestinians vs. Israelis, but that the wider circle of rejectionist states was stoking the fire of confrontation, and often spoiled potential peace moves. A case in point was when Mubarak famously acted as spoiler during the Camp David II peace talks between Ehud Barak and Yassar Arafat. Madaline Albright was exasperated, and Bill Clinton was stunned. And that is Egypt, which currently holds a peace treaty with Israel. The Syrian influence in Lebanon is equally infamous. The assassination of Hariri finally put a price on Syrian adventurism, but the continued arming of Hizbullah by Syria/Iran is naked for all to see. I absolutely agree with you that we must use realism to see the big picture. Unilateralism was a dangerous will-o-the-wisp that Israel grabbed at when some Israelis' worldview was shown to be out of synch as you describe.
