You're claiming one of the founders of the PLOs words are inaccurate and ahistorical? C'mon man, that's just silly.
Herzl used the common language of the time, that's not debated and obviously expected. The fact of the matter is that Jews were already present, had a majority of population in numerous centers within the Land and the European refugees were a minority when the UN partitioned the land. It's also not disputed that Israel granted citizenship to the Arabs who didn't flee during the war in '48, and there's millions of them living in Israel currently as a result. Is Israel expected to grant citizenship to the people who took up arms against them and refused to acknowledge their existence? You can't seriously believe that. That's the definition of fucking around and finding out, those people left under the promise of Israel's destruction, it's not Israel's fault for not letting the Arab League uphold their promises. The Arabs were offered to partition the land, they really should have taken the offer, it was initially more generous than what was offered to the Jews. It's been the same crying ever since.
