If Israel were to return to the pre-1967 borders, I believe they would have the right to the territory because it was their land in the first place and it would be wrong to strip them of their rights to their own land. Although some may believe it is not considered their land anymore, I think they have the rights.
It is not a matter of faith, it is a matter of law, and Israel is breaking international law. They have been occupying Palestine since the 1967 boarders were first established, and it has only gotten worse. If one would compare the 1967 map to the map now, they would see just how little land the Palestinians have now compared to then, let alone to the land the palestinians had in the 1920s. It is not only immoral, but it is horrendous how we just sit back and let the oppression of the Palestinian people continue.
