This article defends the right that Palestinians have to return to the territory governed by Israel. However, it does not defend the duty on Israel to permit return. Whether there is such a duty depends on whether the economic, social and security costs override that right. In order to defend the right of return, it is shown both that the current generation of Palestinians retain a significant interest in return, and that insofar as their interests are diminished, their rights are (...) not diminished proportionally. The interests of Jewish Israelis in excluding the Palestinians are then considered. Their rights of self-determination, it is argued, do not powerfully favour excluding the Palestinians. The economic, social and security costs may do so. Overall, I conclude that either the Israel should grant return to the Palestinians or it should properly acknowledge the right of return and respond appropriately through a powerful effort to compensate and resettle them.
