Rabbi Shlomo Goren was one of the leading rabbinic figures in religious Zionist circles. As the first chief Rabbi of the Israeli military, he had a unique opportunity to influence the development of the Israeli army and its policies. He needed to deal with questions that had no precedents in Jewish law. One of his challenges was the part international law played in the formation of a modern army. Rabbi Goren wished to give a halachic perspective to questions of international law, and to do that, he had to translate the language of international law, a field developed in the modern period, to halachic language. This process led him to evaluate moral positions that are part of international law and the ability of halacha to be part of the modern world.
