Although there's no proof whatsoever for your premise, let's suppose there were Arab families who had been living in the same communities for centuries. So what? Large communities of Jews have lived on the territory that became Iraq for 2500 years uninterruptedly. Are those Jews a different Jewish Iraqi nation, deserving a state in Iraq? Large communities of Jews have lived on the territory that became Yemen for 2000 years uninterruptedly. There was a Jewish Kingdom in Yemen in the 4th century CE. Are Yemenite Jews a different Jewish Yemeni nation, deserving a state in Yemen? I could go on and on and on - there were large Jewish communities that lived for centuries uninterruptedly in other places, before those territories became the countries we know today. So many Jewish nations....where are we gonna put them all? The "not going along" started long before WWII, with the rise of pan-Arab nationalism emboldened by the fall of the Ottoman empire. https://israeled.org/nebi-musa-festival-riots/ https://www.jewishvirtuallibrary.org/the-hebron-massacre-of-1929 I'd expect such a reply from a biased anti-Zionist, not from you. The Ottoman censuses were not reliable. The first reliable census in Palestine was made by the British at the beginning of the 30s. The table in the link gives us numbers of non-Jews, but it doesn't tell us anything about them. We don't know when they arrived in Palestine, how long have their descendants lived there, or even if the numbers include semi-nomadic Bedouins. Speaking of Bedouins, a number of families in West Bank, claiming Palestinian ancestry, are in fact descendants of nomadic Bedouins, including such ferocious nationalists as the Tamimi family (from Saudi Arabia), and the former prime minister Saeb Erekat. But they are native Palestinians... i know Israeli Arabs whose grandfathers came to Palestine from Morocco, Egypt, Saudi Arabia. There are testimonies to immigration of Arabs to Palestine after WWI. The British ignored illegal Arab immigration. Numbers without context don't tell us anything.
