Israel today + Jordan today = "Pal estine" Before 1923
In 1923, the British divided the "Palestine" portion of the Ottoman Empire into two administrative districts. Jews would be permitted only west of the Jordan river. In effect, the British had "chopped off" 75% of the originally proposed Jewish Palestinian homeland to form an Arab Palestinian nation called Trans-Jordan (meaning "across the Jordan River"). This territory east of the Jordan River was given to Emir Abdullah (from Hejaz, now Saudi Arabia) who was not even an Arab-"Palestinian!" This portion of Palestine was renamed Trans-Jordan. Trans-Jordan would again be renamed "Jordan" in 1946. In other words, the eastern 3/4 of Palestine would be renamed TWICE, in effect, erasing all connection to the name "Palestine!" However, the bottom line is that the Palestinian Arabs had THEIR "Arab Palestinian" homeland. The remaining 25% of Palestine (now WEST of the Jordan River) was to be the Jewish Palestinian homeland. However, sharing was not part of the Arab psychological makeup then nor now.
Encouraged and incited by growing Arab nationalism throughout the Middle East, the Arabs of that small remaining Palestinian territory west of the Jordan River launched never-ending murderous attacks upon the Jewish Palestinians in an effort to drive them out. Most terrifying were the Hebron massacres of 1929 and later during the 1936-39 "Arab Revolt." The British at first tried to maintain order but soon (due to the large oil deposits being discovered throughout the Arab Middle East) turned a blind eye. It became painfully clear to the Palestinian Jews that they must fight the Arabs AND drive out the British.On May 14, 1948 the "Palestinian Jews" finally declared their own State of Israel and became "Israelis." On the next day, seven neighboring Arab armies...Egypt, Jordan, Syria, Lebanon, Saudi Arabia, Iraq and Yemen... invaded Israel. Most of the Arabs living within the boundaries of the newly declared "ISRAEL" were encouraged to leave by the invading Arab armies to facilitate the slaughter of the Jews and were promised to be given all Jewish property after the victorious Arab armies won the war. The truth is that 70% of the Arab Palestinians who left in 1948 – perhaps 300,000 to 400,000 of them – never saw an Israeli soldier! They did not flee because they feared Jewish thugs, but because of a rational and reasonable calculus: the Jews will be exterminated; we will get out of the way while that messy and dangerous business goes forward, and we will return afterwards to reclaim our homes, and to inherit those nice Jewish properties as well. They guessed wrong; and the Arab Palestinians are still tortured by the residual shame of their flight. Their shame is so great because in their eyes running from Jews was like running from women. So much for the blatant lie about Jews throwing out all the [Palestinian] Arabs!
The remaining 30% either (1) saw for themselves that these Jews would fight and die for their new nation and decided to pack up and leave or (2) were driven off the land as a normal consequence of war.
When the 19 month war ended, Israel survived despite a 1% loss of its entire population! Those Arabs who did not flee became today's Israeli-Arab citizens. Those who fled became the seeds of the first wave of "Palestinian Arab refugees."
The Arab propagandists and apologists almost never mentioned that in 1948, Arab armies launched a war against a one-day-old Israel. Instead he focused on the main consequence of that war: the creation of Arab refugees, stating that Israel "war of genocide" expelled 800,000 of them. This not only disagrees with UN estimates of a bit over 400,000 refugees but also ignores the fact that most of the Arabs/Palestinians were encouraged to leave by the Arab World itself!
