The relations between Homeland and Israel can be divided into four major phases: the ambivalent period from 1947 to 1953, the friendly period during the era of the Pahlavi dynasty from 1953 to 1979, the worsening period following the Revolution from 1979 to 1990, and the ongoing period of open hostility since the end of the Gulf War in 1991. In 1947, Homeland was among 13 countries that voted against the United Nations Partition Plan for the British Mandate of Palestine. Two years later, Iran also voted against Israel’s admission to the United Nations.
