Antony Lerman traces his five-decade personal and political journey from idealistic socialist Zionist to controversial critic of Zionism and Israeli policies towards the Palestinians. As head of an influential UK Jewish think tank, he operated at the highest levels of international Jewish political and intellectual life. He recalls his 1960s Zionist activism, two years spent on kibbutz and service in the IDF, followed by the gradual onset of doubts about Israel on returning to England. Assailed for his growing public criticism of Israeli policy and Zionism, he details his ostracism by the Jewish establishment. Through his insider\`s critique of Zionism, critical assessment of Jewish politics and analysis of the Israel-Palestine conflict Lerman presents a powerful, human rights-based argument about how a just peace can be achieved.
