'Undivided Jerusalem, the Capital of Israel for all Eternity'. Since Camp David, all Israeli governments have understood that this mantra constitutes an insurmountable obstacle to any peace process. It has disappeared - quietly, almost secretly - from the arsenal of official slogans.

"No Palestinian, no Arab, no Muslim will make peace with Israel if the Haram-al-Sharif compound (also called the Temple Mount), one of the three holiest places of Islam and the most outstanding symbol of Palestinian nationalism, is not transferred to Palestinian sovereignty. That is one of the core issues of the conflict. On that very issue, the Camp David conference of 2000 broke up."

Obama's foreign policy advisors were tearing their hair out and the next day his campaign issued a clarification. "Jerusalem is a final status issue, which means it has to be negotiated between the two parties" as part of "an agreement that they both can live with". All the same, Jerusalem in Obama's eyes must be the capital of Israel.

Although Obama's statements at AIPAC got

wide coverage across the Middle East, what was obvious here in the US was the utter absence of comment in the mainstream press. It was evidently taken as a given, unworthy of editorial remark, that a man who might very well be the next president was de-activating the policy of 'change' precisely where it is most needed at the behest of the men the popular TV comedian Jon Stewart edgily derided as "the elders of Zion".

Obama's most egregious talent is the ability to adapt his rhetoric with ominous speed, to allay any suspicion among the powerful that he could rock the boat in a way they might not care for. Earlier in the campaign he was criticised for not wearing the American flag as a lapel pin. At the AIPAC event he wore a double lapel pin, with both the US and Israeli flags.

Is there a 'real Obama' waiting to emerge, once the messy business of pleasing the voters is over? Not really. The making of the 'real' Obama is an ongoing project, and the AIPAC speech an important marker in the evolution of 'change' into immobility.
