I don’t think the issue is about if the Jews existed in Palistine. The question is if most of them left after 70 AD can they come back and displace the people (Palistinians) living there in 1948???? There lies the root of the conflict. Yes, there was a Jewish quarter in Jerusalem centuries before 1948, but the majority of the people who settled in Palistine after the Jews were carried off by the Romans were not Jews. You cannot tell people living in Palistine for 2300 years to move aside for the Jews returning from a Holocaust. To argue that because there was a surviving enclave of Jews who never left since 70 AD till 1948, the Jews from Europe can now take all of Palistine for themselves is like the Chinese one hundred years from now claiming New York City and San Francisco from the US because there is evidence of a Chinatown for over a century.
The Jews were given basically junk land in 1948, it was because of wars that they got the West Bank, Golan, Sinai, and Gaza. The land was never really a country and always under foreign rule.
Does this mean the Turks should vacate Istanbul? The United States return Texas to Mexico? Give Guam back to Spain?
Your question is about the jews but it applies to the
arabs who left in 48 also, why should they be allowed
back, they left too.
