Jason Hamaan I will answer this myself!
UNGAR 181 did not mention a “Palestinian state”, but partitioned the Mandate for Palestine into two sets of 3 areas each, allocated to “the Arab state” (mentioned 16 times in the resolution) and “the Jewish state” (mentioned 22 times in the resolution).
The Jewish shadow government (“Yishuv”) accepted UNGAR 181. The Arab shadow government (Higher Arab Committee for Palestine) rejected the resolution and started a civil war, hoping to drag the Arab League countries into a conflict that would eradicate “the Jewish state” before it could be born.
The Yishuv declared the establishment of the State of Israel the day before the end of the League of Nations Mandate for Palestine expired. The Higher Arab Committee for Palestine did not. Under international law, those areas allocated to “the Arab state” in UNGAR 181 became “terra nullius”.
A war followed, with Israel against six Arab armies whose declared war objective was genocide. The Arab armies lost that war, due as much to their own incompetence, distrust of each other, corruption and cowardice as to any Israeli heroics.
In the end, Egypt was illegally occupying the Gaza Strip and Jordan was illegally occupying the West Bank and the eastern part of Jerusalem (acquisition of territory by a war of aggression). These two occupiers had 19 years to establish a Palestinian state, but didn’t do so. In fact, the original version of the Palestinian National Charter (1964) specifically waived all Palestinian claims to the areas mentioned above:
“Article 24. This Organization does not exercise any regional sovereignty over the West Bank in the Hashemite Kingdom of Jordan, on the Gaza Strip or the Himmah [Jerusalem] Area. Its activities will be on the national popular level in the liberational, organizational, political and financial fields.”
The Original Palestine National Charter (1964)
Apparently, as long as these areas were under Arab control, they weren’t “Palestinian territories”. It was only when Egypt and Jordan lost control of these areas to Israel during the 6-Day War that they suddenly became “Palestinian territories”.
Demanding something you were offered and rejected 20 years before isn’t how life works. It’s not a schoolyard game where the loser can cry “Do over!”
It’s time for the Palestinians to accept the consequences of their actions, admit their multiple failure to destroy Israel, swallow their “Arab Pride” and “Arab Honor” and move on. If the positions had been reversed, they would not have been so magnanimous, and they admit it.
Now, what “Palestinian territories” were you talking about
