The international community has recognized no line between Israel and the Arab states unless it is defined in a peace treaty or the IDF has captured territory beyond the line. The Green Line was not accepted as a border by the Arab states between the years 1949 and 1967. This position of nonrecognition was tollerated by the international community. When Israel captured territory beyond the Green Line suddenly the Arab states began talking about the Green line as a border. This change in the Arab position has come to be supported by much of the international community even though the two peace treaties signed between Israel and two of its neighbors are not consistent with this stand. So I suspect that if Israel unilaterally sets a new border it will not be accepted by the international community unless it becomes part of a peace treaty or future military conflict leads to Israel's gaining possession of significant amounts of territory beyond the new border.
