Jordan was taken out of the equation at the San Remo conference in the early 1920s.
When the Jewish representatives for the future state of Israel came to the United Nations in 1947 they argued VERY STRONGLY for a partition plan with Jordan NOT THERE. The reason why was that “without the partition” the Arabs outnumbered the Jews by TWO TO ONE and it would have been an ARAB STATE.
SO ... the Jews got the Partition (and they celebrated all over the world - and thus - they got their JEWISH MAJORITY in their partition, which is what they wanted.
When the Arabs attacked, later in 1948, the eventual cease fire lines held closely to the “partition” so that the Jews KEPT THEIR MAJORITY and thusly making it “the Homeland for the Jews”!
I think also the Jordan issue got settled with and I am digging into brain now, hopefully not because of the early summer heat, but also was there a “black September” incident that forced Jordan to get rid of any supporters of a seperate Palistine? Thank-you for your response.
