As Israeli President, Peres is not in a position to be anything but a fig-leaf. That's what Israel's Presidency is: an honorary post with no political clout. Time was when we had presidents from the scientific and intellectual spheres, but they are long gone (to the great regret of some of us). Peres was a shrewd, most claim wily, career politician. He now carries out the tasks of a totally ceremonial President. It's Netanyahu and his coalition who have the power. It is they who need to be held to account. If President Obama mistook Peres's mandate as being similar to his own, he didn't do his homework. If you think Peres would still be President after doing what you want him to do, you are mistaken.
