How Obama acts regarding Iran and Abbas will show if his deeds match his words. But to continue to act as if he is an enemy of Israel is both counter-productive and tactically wrong, and will only alienate from both Israelis and American Jews those conservatives who continue to act in such a manner. If Obama makes a wrong move, then call him on it. But encourage him to — as a friend of Israel — do what has to be done to secure the future of the Jewish state.
