Obama won the nobel peace price not thanks to his political actions but his promisses for the world peace. He is also aware of that situation and probably he knows that he will be remembered as the worst nobel owner ever if his administration goes on to support Israel`s wrong policies. this is the personal reason. But political reason is much more important coz although once they had once strong allies w/ Israel,other countries do not buy Israel`s excuses anymore. So, an american government promising a worldwide peace should prove itself over Israel first.
