Israel has already forfeited Jerusalem

Jews barred as U.S. helps Arabs fortify their presence in holy city By Aaron Klein WorldNetDaily
JERUSALEM – Sections of Jerusalem have essentially been forfeited on the ground to the Palestinian Authority, while Jews, including local landowners, are barred from entering parts of Israel's capital, a WND investigation has found.

The probe further determined the U.S. has been aiding the Palestinians in developing infrastructure in Jerusalem.

Also, it has emerged, the Israeli government has failed to stop Arabs from illegally building thousands of housing projects on Jerusalem land purchased and owned by a U.S. Jewish group for the express purpose of Jewish settlement, culminating in an Arab majority in the neighborhoods.
