Question: How many years did Yitzhak Rabin serve in government? Passage:At the very beginning of the Occupation the devout rabbi and philosopher Yeshayahu Leibowitz thought the occupation of the West Bank and Gaza would imperil Judaism itself, and advocated immediate withdrawal. As the years passed, his antagonism to Israel's military successes led him to speak of "Judeo-Nazis" and the "Nazification of Israeli society", a position which did not stop him being nominated for the Israel Prize in 1993 by the government of Yitzhak Rabin. Israeli demographer Oren Yiftachel considers not only the settlement policy in the West Bank, but the state of Israel itself as an example of a Judaizing ethnocratic regime, which he defines as one that "promote(s) the expansion of the dominant group in contested territory and its domination of power structures while maintaining a democratic facade." The activist Jeff Halper speaks of a "matrix of control" underlying the occupation, while the Israeli philosopher Avishai Margalit, following the Indologist David Dean Shulman, speaks of its "intricate machinery". Neve Gordon analyses at length the attempts to so normalize things that an "invisible occupation" is created.
