While in the Torah we find that G-d promised Abraham/Isaac/Jacob that their offspring would receive the Land of Israel (the Land of Canaan in the Torah), we also find that G-d promised Ishmael, the eldest son of Abraham, that he would be made into a great nation. In other words the Jewish people, amongst others things, were promised sovereignty rights over the Land of Israel while the Arabs, via Ishmael, were promised to be made into a great nation.
Perhaps this is the reason that in Islam, the religion which the Arabs brought to the world, there is the concept of the ummah, the nation of Islam, but no corresponding concept that attaches the ummah to one specific land.
This being the case, it appears that the ongoing Arab claim to rights of sovereignty over parts of the Land of Israel infringes upon the blessing that was given to the Jewish people. The Arabs were only promised peoplehood but not a specific land. This is very clear from the Torah.
Wait a minute, if the Arabs don’t read the Torah how are they supposed to know this?! Thus it appears that the problem is not with the Arabs but rather with the Jews. In other words if we, the Jewish people, are not familiar with the promise of the land or yet worse we reject it, then like a vacuum someone else will be pulled into the empty space in order to declare sovereignty over it. This, in a nutshell, is what is happening.
