Israel defending itself.
The basic principles have been accepted by virtually the entire world, including the Arab states (who go on to call for full normalization of relations), the Organization of Islamic States (including Iran), and relevant non-state actors (including Hamas). A settlement along these lines was first proposed at the U.N. Security Council in January 1976 by the major Arab states. Israel refused to attend the session. The U.S. vetoed the resolution, and did so again in 1980. The record at the General Assembly since is similar.
There was one important and revealing break in U.S.-Israeli rejectionism. After the failed Camp David agreements in 2000, President Clinton recognized that the terms he and Israel had proposed were unacceptable to any Palestinians. That December, he proposed his "parameters": imprecise, but more forthcoming. He then stated that both sides had accepted the parameters, while expressing reservations.
Israeli and Palestinian negotiators met in Taba, Egypt, in January 2001 to resolve the differences and were making considerable progress. In their final press conference, they reported that, with a little more time, they could probably have reached full agreement. Israel called off the negotiations prematurely, however, and official progress then terminated, though informal discussions at a high level continued leading to the Geneva Accord, rejected by Israel and ignored by the U.S.
Comment: For the past 40 plus years, the U.S. has rejected every UN resolution that would allow Palestine to be recognized as a State. The U.S. continues to provide (illegally) money and weapons to Israel in support of occupation and genocide in Palestine. The U.S. media NEVER reports an accurate picture of what is going on in Palestine. Israel is forever the victim. If the American population were exposed to the atrocities they were funding in Palestine (via the media), they would discover that Israel is the aggressor, not the victim, and public support would disappear.
