The main opposition leader in Israel, the head of the center-left Zionist Union Isaac Herzog, has today declared a two-state solution to be “impossible,” telling a high-profile security conference that the goal should be to build as big a wall as possible to wall off as many Palestinians as possible.

Prime Minister Benjamin Netanyahu took considerable heat during the most recent election campaign for his similar panning of the peace process, leading many to believe Herzog’s coalition represented the only real chance for a peace process.
