To my knowledge, "Palestine" never existed as it's own country. Palestine was actually to Jordan what a county in the U.S.A. would be in relation to any given state. Kind of like the way "Transylvania" is a county inside Romania. I gather that pressure by the UN and the USA on Jordan allowed the State of Israel to be formed by carving the land from Jordan, typically among the most "laid back" of the middle eastern nations. The Jordanians didn't much care at the time. It's not like there was any oil to be had there. There was no way they could have foreseen the powerhouse that Israel would become...I mean it's not like they were experts on Biblical prophesy. LOL
