Answer:
Both Israel and Palestine have territorial claims on the same territories in the Middle East, basing their claims on different, but equally valid historical circumstances: on the one hand, Israel does so insofar as the territory is part of the so-called Promised Land of the Old Testament, while Palestine does so as its natural inhabitants of said territory for centuries.
In both cases, these are valid reasons that cannot be ignored; the problem is precisely that territorial claims are in conflict. Therefore, it should be possible to find an intermediate solution, which satisfies both nations and in which both should give up a part of their claims. One possibility would be to divide the territory, creating two sovereign states with shared possession in important places like Jerusalem.
