"Whereas recognition has thereby been given to the historical connection of the Jewish people with Palestine and to the grounds for re-constituting their national home in that country."
What was the JNH under the Mandate?
ART. 7.
The Administration of Palestine shall be responsible for enacting a nationality law. There shall be included in this law provisions framed so as to facilitate the acquisition of Palestinian citizenship by Jews who take up their permanent residence in Palestine.
Why would the Palestinians and the Jews become nationals and citizens of a place that was not a state?
I don't quiet understand what are you alluding here...
The JHN was the representative of the Jewish majority,
and acquisition of citizenship is the formal relationship
between a govt, in this case the British Mandate Admin
and the residents of a territory it administers.
The Mandate as you yourself stated many times, was not a sovereign state,
neither founded and administered by or designated for an Arab state.
It was merely and administration, designated by international law,
for helping in the
re-constitution of the Jewish National Home.
