Barack Obama entered the White House more deeply informed about and sympathetic to the Palestinian cause than any incoming president before him. He had attended and spoken at numerous events organized by the Arab-American and Palestinian-American communities, in which he had numerous contacts, and he had repeatedly criticized American policy, calling for a more even-handed approach toward Israel. Yet if there has been a distinguishing feature of Obama’s record on Israel-Palestine, it is that, unlike his recent predecessors, he has not a single achievement to his name. In the view of some top advisers, Obama’s final months in power are a unique opportunity to correct the record, and, more important, score an achievement that his successors could scarcely undo.
