I was deeply interested in … Zionist affairs and activities – or what was then called ‘Zionist,’ though the same ideas and concerns are now called ‘anti-Zionist.’ I was interested in socialist, binationalist options for Palestine, and in the kibbutzim and the whole cooperative labor system that had developed in the Jewish settlement there (the Yishuv) … The vague ideas I had at the time [1947] were to go to Palestine, perhaps to a kibbutz, to try to become involved in efforts at Arab-Jewish cooperation within a socialist framework, opposed to the deeply antidemocratic concept of a Jewish state (a position that was considered well within the mainstream of Zionism)
