It's a well-written, well-produced, convincingly acted, no surprise considering that the star is Edward G. Robinson, fund-raising appeal to help the struggling Jewish community -mostly Holocaust survivors*- in the HolyLand aka "Palestine." Obviously, even though the year it was produced is 1948, it predates the declaration of the State of Israel.
Apparently, at that time, it was clear to many/most that Palestine was the name of the Jewish Homeland. In marketing the principle is to use the most easy to recognize name/term. Only post-declaration of the State of Israel did the Arabs, or their anti-Jewish supporter adopt the name Palestine and invent a new nationality to compete with Jewish History.
The original aim of Islam was to supplant/replace Judaism. That's why it adopted many of our Biblical characters and narrative. That's why its followers have been trying to steal our Land and destroy our State.
We must be inflexibly strong and determined to win it all back!
