In regards to the land that God has promised Israel, Genesis 15:18 declares to Abraham, “To your descendants I give this land, from the river of Egypt to the great river, the Euphrates.” God later confirms this promise to Abraham’s son Isaac and Isaac’s son Jacob (whose name was later changed to Israel).
Exactly. The seed of Abraham isn't confined solely to Jews. Hence the song "Father Abraham." Rabbinic tradition says that Gods was only referring to the Jews, but scripture doesn't back that up. In fact scripture makes clear that being Jewish alone, does not qualify one. So it begs the question, are you willing to go with a tradition created by man, over rights to a land, than the scripture that seems to be contrary to it? Let me know if you need verses. I'm away from my laptop now.
