The reality is what 242 says is as irrelivent as 181 of 1947. The very fact we are talking about creating a palestinian state is against the terms of 242 which was supposed to be about negotiating the return of some ( not all land ) to the arabs who lost it in 1967 in exchange for a just and lasting peace. Resolution 181 in 1947 proposed giving Israel 55% of mandate Palestine minus Jaffa which would have gone to the arab state and Jerusalem which would have been an international zone. Israel never officially agreed to those borders and after the war of independence it was left with 78% of mandate Palestine, Jaffa & Jerusalem was divided for the first and last time in its history. Even that Israel did not set as a border. In 1967 we had another war and when the ceasefire lines were drawn Israel got much more land. Israel has never declared its border and neither has the UN officially the so called Green Line is just an unofficial border but legally it is not Israel's border. Tel Aviv & Haifa under Israeli law have the same legal rights as east Jerusalem and the Golan which were annexed by Israel and so in theory if the government had the right to negotiate those places then they would have the right to negotiate Tel Aviv & Haifa.
