You are making things up. The drafters of the resolution had no reason to specify the fact that the Arab population owned 85% of the land if it were not the case. You are just trying to rewrite history. The usual Zionist attempt at justifying the theft of land. It is becoming ridiculous to argue with people that make up fairy tales when the facts are available in black and white.
"164. The Arab population, despite the strenuous efforts of Jews to acquire land in Palestine, at present remains in possession of approximately 85 per cent of the land. "
There is no qualification, no reservation or caveat in that statement. Your prevarication is just a lie, you are trying to skirt the truth with bullshit.
You comment depicts a fundamental ignorance of the facts
Turkey transfers Ottoman land records to Palestinian Authority
Even before 1917, Jewish and Zionist institutions had purchased large tracts of land in Palestine from absentee landlords, who lived mainly in Syria and Lebanon. These landlords had previously leased their property to local farmers, but were happy to sell it for the right price, without giving a thought to their tenant farmers. Nevertheless, Palestinians view these sales as more legitimate than those that took place during the British occupation that began in 1917.
