The last thing in the world that Israel wants in the Middle East is peace.  A PressTV article online presses this point home.  It is entitled:

    Israel's goal in Syria: Prolong war, maximize destruction
    http://www.presstv.com/detail/2013/05/05/301972/israel-using-syria-war-to-spread-sectarian-chaos-in-me/

           Excerpt from the article:

    "...In other words, a weak, sick, chaotic Middle East is good for Israel. A healthy, thriving, united Middle East is Israel's worst nightmare.
    So Israel's strategy is to incite wars and do everything possible to keep them going. If one side appears to be gaining the upper hand, which could lead the other side to accept a peaceful resolution, Israel will intervene in favor of the side that is losing, in order to prevent peace from breaking out.
    Zionist ultra-extremist Daniel Pipes recently articulated that strategy:
    “Evil forces pose less danger to us when they make war on each other. This (1) keeps them focused locally and it (2) prevents either one from emerging victorious (and thereby posing a yet-greater danger). Western powers should guide enemies to stalemate by helping whichever side is losing, so as to prolong their conflict.”
