I’m still trying to figure out what the relevance of the Jerusalem Post is. Both it and the Jewish Telegraphic Agency were founded by Jacob Landau, a left-leaning journalist born in Austria.
The League of Nations announced that the Jews wanted to call their homeland “Israel” long before WWII started. The Hebrew name of what became the Jewish Agency for “Palestine” (founded in 1908) was “HaMisrad HaEretz Yisraeli”. The Mandate (named by the British, not the LON) stated that provision be made for the Jews to “reconstitute (their) homeland”, not under the name of “Palestine”.

And then came the argument over the name of the State-to-be. One member requested the name “Judea”, but others pointed out that this Biblical name only referred to one region within the prospective state. Others proposed the name “Zion”, citing the benefit of the Jews in having the last word at the United Nations and other international forums since they would be voting at the end of the alphabetical list. But others argued that “Zion” was also the name of a hill, and that this might be confusing. Ben-Gurion suggested the name “Israel”, and at the last moment this name was approved.

Look at the Jewish officials reference to the new country - which had not been formed yet. They called It - the Jewish State.
Quoting ...
On May 14th Prime Minister David Ben-Gurion reads the proclamation of nationhood. Striking the speaker’s table for emphasis, he announced, “The name of our state shall be Israel.”
The American statement recognizing the new State of Israel bears President Truman’s last-minute handwritten changes. American recognition came shortly after midnight in Palestine, just minutes after the new nation was proclaimed.

The significance of the “Palestinian Post” (which is now called the Jerusalem Post) is that people of the day had no problem understanding why it was called the “Palestinian Post” - since the people there were already referred to as Palestinian Jews and Palestinian Arabs.
