IIRC, that was what was proposed in the Balfour Declaration after World War I. No one got around to the actual creation of a Jewish state (the whole of Israel and Jordan remained “the Palestinian Mandate”) until after World War II when the horrors of the Holocaust were revealed, and then Israel was roughly divided by an “X”, with the north and south sectors Jewish and the east and west sectors Arab.
BINGO! We have a WINNER!
