Which one? The 1937 borders? 1946? 1967? 1974? As a American Jew my feelings about this are really complex. I genuinely believe the best and safest place for Jewish people to live in peace is HERE in America. It’s not perfect and discrimination still exists but it’s not a constant war zone. Frankly, the Diaspora is still a significantly bigger population than Israel. That should be a clue. And While I want Israel to exist, I don’t want it to mean destruction of the Palestinians. That’s a violation of the Covenant. The fully political construction of the State of Israel doesn’t fullfill the Covenant and no political construction ever will fulfill the sacred bargain. In Torah, the idea for a Land (Not State) of Israel is born in tandem with the idea for a People of Israel. God’s covenant with Abraham includes a promise that Abraham’s descendants will inherit the area from the river of Egypt to the Euphrates. The Modern State of Israel is a sliver of that area. Also, frankly, G-d’s promise was to not only about Isaac, but to all the children of Abraham. G-d saw Hagar’s suffering and promised that although her child was not the child promised to Abram, he would nevertheless make Ishmael’s descendants into a great nation also. All of Keturah’s sons are decent of Abraham and are ALSO included in the agreement. So to say to the younger religions “You can’t be here and have no rights here. This place is ours alone.” Is itself a selfish perversion of the agreement. But that is the argument that many are making. I also recognize that the Government of the State of Israel has made some truly awful choices... and so has Palestine. I also know that there are Arabs that don’t think ANY independent Jewish state should exist. There are Israelis that don’t think that any Palestinian State should exist. Both groups are WRONG. The promise of a “Great Nation” was made to both. The situation of modern Israel and Palestine is so complex and has so much bloodshed and just roiling ugliness that it makes our US political differences look like children’s quarrels. From the standpoint of Torah, G-d’s promise was made to all and traditionally G-d takes negative view of familial genocide. But I am a proponent of the “fabric of society” model of history and frankly, until both sides acknowledge that the other has a right to exist AND that Jerusalem is a holy city for EVERY Abrahamic religion and can’t “belong” to ANYONE alone, it isn’t going to resolve. Jerusalem IS the lead weight. So until that is taken off the table, the other issues can’t resolve.
