“This resolution basically makes Israel illegal”
Most countries (including the US) have said that repeatedly. From day 1 after the 6 day war Settlements had been identified as illegal by most of the world. Immediately after the war 242 said referred to the “inadmissibility of the acquisition of territory by war”
1397 most definitely had long term ramifications, it was the first to call for a Palestinian state.
And there have been resolutions regarding the settlements, example 465:
“Determines that all measures taken by Israel to change the physical character, demographic composition, institutional structure or status of the Palestinian and other Arab territories occupied since 1967, including Jerusalem, or any part thereof, have no legal validity and that Israel’s policy and practices of settling parts of its population and new immigrants in those territories constitute a flagrant violation of the Fourth Geneva Convention relative to the Protection of Civilian Persons in Time of War and also constitute a serious obstruction to achieving a comprehensive, just and lasting peace in the Middle East;”
Again I am not defending Obama (the above was under Carter’s watch the US voted for it) , I am just trying to understand why this is so unprecedented
