The Israelis also haven't held "sovereign territory" in the Western modern sense, ever. Over 2000 years ago, since at least the Macabean Kingdom, there hasn't been a Jewish government there and that government is far from being a state or proving that Jews today in the 21st century, have ancestors that owned any property on that land. Millions of Jews today descend from converts to rabbinic Judaism and no where in God's word does it say anything about Jews having an unconditional right to any real estate, especially after rejecting Jesus Christ as their Lord and Savior.
The Palestinian Arabs have been there forever since they are the Indigenous people of the Levant (which includes the Holy Land), who converted to Islam starting approximately 1380 years ago and throughout the early Middle Ages. Both Jews and Christians, who were originally speaking Western Aramaic, adopted Islam as their religion and the Arabic language and culture. They're not true Arabs from the Arabian peninsula, genetically or otherwise, as attested to by Israeli genetic studies conducted by Jewish Israeli scientists from the Hebrew University.
To suggest that Jews from Poland and Crown Heights Brooklyn, are more likely to be direct descendants of Abraham, Isaac, and Jacob than Palestinians, is laughable.
