Strange how Barak can talk about the Palestinians missing an opportunity when he himself has recently approved of additional building in the West Bank. It appears that Barak has not yet come to terms with the fact that additional settlement in the West Bank is a major infringement upon Palestinian statehood. As long as building in the West Bank continues in any shape or form, any Israeli participation in the summit conference is nothing more than a photo op, and it will accomplish nothing more than that.
