You're spot on. Not only Obama but before him GW Bush during his 2 mandates gave 'carte blanche' to Sharon to get rid of Arafat. The palestinians are on their own with no political, nor military, nor financial power against a nuclear power called Israel. And people in Israel and their leaders still have the guts to pretend the palestinians are a threat for their existence. The US are not a peace broker and they have never ever been one.
