Nobody elected Obama king of Israel or prince of the Palestinians. This futile meddling is just another aspect of the infinite modern faith in the magical powers of Big Government and bureaucracy to remake the hearts and minds of men. The Middle East and the US would both be better in the long run if we left that part of the world alone.
Two words make that impossible for America to stop meddling: Saudi Arabia. They say jump, the POTUS asks how high. They say pressure Israel, Israel gets American pressure. That way, they can demonstrate their usefulness to the cause of Islam to the fanatics that want them dead, and continue to enjoy their palaces, Lear jets, harems and hookahs.
