With most of the 193 General Assembly member states sympathetic to the Palestinians, the vote is certain to succeed. Several key countries, including France, have recently announced they would support the move to elevate the Palestinians from the status of U.N. observer to nonmember observer state. However, a country’s vote in favor of the status change does not automatically imply its individual recognition of a Palestine state, something that must be done bilaterally.

The Palestinians say they need U.N. recognition of a Palestinian state in the West Bank, Gaza and east Jerusalem, the lands Israel captured in 1967, to be able to resume negotiations with Israel. The non-member observer state status could also open the way for possible war crimes charges against the Jewish state at the International Criminal Court.

In a last-ditch move Wednesday, U.S. Deputy Secretary of State William Burns made a personal appeal to Palestinian President Mahmoud Abbas promising that President Barack Obama would re-engage as a mediator in 2013 if Abbas abandoned the effort to seek statehood. But the Palestinian leader refused, said Abbas aide Saeb Erekat.
