STATEMENT OF VERIFIED FACT: 77% of the "Jewish Homeland" was split off in 1924 or so to form the Kingdom of TransJordan, where Jews were not allowed to settle. This was by the Mandate Power ( GB) . The remainder was to be the new "Jewish Homeland"
Those were the LAST borders accepted by the Arab League.

QUESTION: Shouldn't we go back to them, rather than the so-called "1967" borders that were the result of truce lines from the 1948 war?

Yes or no, feel free to explain your reasons.
