Probably both. As insightful as this article is, Netanyahu has given no indication of being the type to turn away from his "base camp" - in the past, any concessions he made were only because he was dragged into them. He has not come across as the sort of leader determined/fickle (you pick) enough to pull such a move. Second, which Mr. Benn does not address at all, I have serious doubts that the Likud party would ever let him pull this off if he tried. It simply crosses a the red lines of too many party ideologues. Netanyahu would either be toppled from within, or he'd further fracture the knesset's second-largest party, the opposite to the "fusion" trend Mr. Benn hopes for. A very interesting read though.
