israel must be very careful in dealing with the arab israeli minority, so as not turn them into a "fifth column".
but there are limits to the use of the carrot, and sometimes it is also necessary to resort to the stick.
if this "leader" is such an outspoken advocate for faux-palestinian rights, maybe it's time to call his bluff, strip him of his israeli citizenship (legally, of course), and dump his sorry ass in abbas' lap in ramallah.
