Cute video. I'm surprised to learn that Pat Boone wrote the lyrics to that song.
But if you read scripture it clearly says that God gave the land to the "seed of Abraham." That seed, according to the DNA evidence, is the Palestinians who are 85% Jewish whereas the Ashkenazi Jews, who are claiming the land, are only 75% Jewish on their father's side and just 50% on the mother's side. But under Jewish law I don't know if the father's side counts or not.
