God promised the land to Abraham. God gave the Jews Israel.
Since jewish religion focuses on God and he gave the land to to them then that should mean it is rightfully theirs. Their is no force for powerful than God.
Genesis 35:12
The land I gave to Abraham and Isaac I also give to you, and I will give this land to your descendants after you."
The Muslims may have different practices, but they can’t use this as a reason because they can still try to understand what the Israelis are trying to mean by this.
On the surface, Muslim belief about God--"Allah" in Arabic--appears to closely resemble that of Judaism. God is One, and He alone is to be worshiped
History shows that this claim is false. The Jewish started an empire before you were there. It is in this video, history never lies. https://youtu.be/4FspfOI_YRU?t=18
The international community granted the Jewish people the land in 1948. United Nations including the U.S. gave land in Palestine to Israel. The U.N is a powerful force because it is all of the nations together making decisions and you can’t over rule that. If they make a decision you can’t overrule it with a few people. All of the nations chose to have this decision. When all of the nations make a decision, people have to listen to that decision.
