The other ways around. It was the Arabs, who invaded the Land of the Jews. Arab leaders sought to “throw the hews into the sea” The cowards left when the Mufti and other Arab leaders told then to.

AIM TO OUST JEWS PLEDGED BY SHEIKH; Head of Moslem Brotherhood Says U.S., British ‘Politics’ Has Hurt Palestine Solution
Special to THE NEW YORK TIMES.
By Dana Adams Schmidt, Aug. 2, 1948
CAIRO, Egypt, Aug. 1 — Sheikh Hassan el-Bana, head of the Moslem Brotherhood, largest of the extremist Arab nationalist organizations, declared in an interview today: “If the Jewish state becomes a fact, and this is realized by the Arab peoples, they will drive the Jews who live in their midst into the sea.”

it’s not quite that simple - Postel, you refer to the 1948 war.
But, let’s dial back to the time of Christ (I’ve just taken that date - we could start earlier but it leads the same way) - the population of what is now the land of Israel was occupied by a multi-cultural mix of Judeans, Samaritans, Nabateans, Syriacs, Romans, Greeks, etc.
In 70 AD when the temple was destroyed, the Jews still remained. But Jerusalem was razed to the ground — what we call “ancient Jerusalem” today dates to only 70 AD - and is the Roman city of Aelia Capitolina built by Hadrian around 120 to 132 AD
In 132 AD after the Bar Kochkba revolt (and the previous Kitos war when the Judaeans had acted like jihadis slaughtering gentiles in Cyprus and Cyrene - note “gentiles” as in pagans) was when the Roman authorities said enough is enough, and banned Jews from entering Jerusalem and much of the environments.
BUT Jews remained in the ares - both “ethnic Jews” i.e. those who became pagans and “religious Jews” - remember also that only around 130s do we get the separation of the 2 post-second-temple Jewish sects: the Rabbinical Jews (”Jews” as we call them today) and the Jesus-movement Jews (”Christians” as we call ourselves today).
Constantine allowed Jews to migrate back and to visit Aelia Capitolina i.e. Jerusalem once a year.
There were Jews in the city when the Arabs conquered it in the 7th century from the Roman Empire. In fact thew Jews were initially left in charge.
But over the century you had not only “Arabs” moving in but also Syriacs getting Arabized, Samaritans and Jews getting “Arabized” as in culture and language.
And many converted to Islam.
In the 1800s when Aliyah started, there were still small groups of Jews living in what would be the modern state of Israel but there were “Arabs” as in Arab speaking peoples who were not Jews.
They didn’t call themselves Palestinians - they probably referred to themselves by their religious group.
The Jews did, in 1947, push out Arabs from some areas and were pushed out of other areas by Arabs.
In my opinion The “Palestinians” should agree with the existence of Israel and join it as Israeli Arabs already do - the Israeli Arabs are citizens, can vote and stand for elections and are represented in parliament
