Every American and Israeli leader must make their "peace attempt". Usually, this consists of nothing but talk. As long as Israel profits by avoiding peace and pays no penalty for it, they will continue to do so. Who can blame them? The American leadership is to weak and unconcerned to want to take on the Jewish Lobby. This means that the talks are always held in bad faith and are nothing more than a photo op for America and Israel. The Palestinians do not profit from this charade and are tired of being played for fools.
