The Russian response is everything that would be expected by sensible individuals who would not want to overwhelmingly favor one side in the negotiations. The US declaration is self-contradictory, calling for a 'viable' Palestinian state based on the 1967 borders while also calling for a 'Jewish state' that honors 'developments' on the ground. Everyone knows by looking at any map that these 'developments' push the border into the West Bank, thereby making the 1967 border a non-possibility. Unless Israel is willing to say that it is going to keep 50-60% of the 1967 border, and push the rest of it inside the West Bank so it can cut off the land and still control the Palestinian state whenever it feels it will serve its purpose.
