What if a motion to recognize Palestinian statehood comes before the United Nations Security Council and the United States elects not to use its veto?
The veto power only resides in the five permanent members - the United States, Great Britain, France, Russia and China. Of the five, the United States has been Israel's only steadfast ally on the Security Council, regularly vetoing any effort deemed unwelcome by Israel.
Obama alone controls his country's vote at the Security Council. Of the other members, Russia and China could be expected to back the Palestinians. France, too, is also onside and it's hard to imagine the Brits wouldn't follow America's lead.
Once recognition of the Palestinian state had the power of the Security Council behind it, the legitimacy of Netanyahu's occupation would be shattered and actions could be instituted, perhaps beginning with punitive sanctions, to lift the Israeli siege.
