Except those who deny the rights of the Palestinians to live in their homeland.
Both the Jewish people and the Arab Palestinian people have the right to live in their homeland. Both the Jewish people and the Arab Palestinian people have the right to independent sovereignty in their homeland. They are collective, inter-generational rights.
No one on the Israeli side is trying to deny those rights to the Palestinians**. Those rights are certainly being denied to the Israelis, in principle if not in practice.
**Occasionally, there is conversation on the Israeli side that the Arab Palestinians are not currently CAPABLE of applying those rights. Some even suppose they will never be capable. Hence, the discussion of another Mandate to help assist them in developing that capability.
