Unfortunately President Obama is only going through the motions on Iran. At best he is working for a slowed down, controlled Iranian acquisition of nuclear weapons technology. He is not sympathetic to Israel, has no commitment to her on any emotional or intellectual basis and has riddled his administration with new-lefty anti-Zionists and anti-neoconservative "pragmatists" and deeply wishes to extract Israeli concessions to get closer to Arab and Islamic centers of power, regardless as to their abiding hatred of Israel (or Jews). It is not politic to directly and rashly confront an American President but good luck with those second chances.
