UN ‘Geneva II’ Syria peace summit opens today - what will it achieve?

Any chance to get the many sides talkking is a good thing. From my recent trip to the Turkish / Syria border I am strongly of the view that we must have a transitional government that accomodates all sides. This will probably require UN monitoring as until the UN agrees to enforce a peace there will be no peace with Russia continuing to back, and providing weapons, to Assad. I met many of the moderate Syrian Opposition leaders 10 days ago and I wish them well.
