Avraham Burg: chauffeured hypocrite
And partial prophet.
Yes, Burg is a paragon of self-righteousness ("so attached to Zionism," wrote a commentator in Haaretz, "that he drove around with a chauffeur paid for by the Sochnut years after he left its employ"), but he makes many thought-provoking points about problems afflicting Zionism. (English here.)
NB: I don't at all agree with his misguided political analogies, and I don't think Israeli society is basically violent. But I do think Zionism suffers from weaknesses, and few other Zionists (or ex-Zionists) besides Burg are pointing these out with such uncompromising clarity.
