From the Palestine Post, November 30, 1947:
Again, no Arab nation is talking about accepting a Palestinian Arab state! It's as if they didn't think that Palestinian Arabs were a nation.
You can almost imagine them saying words to the effect that there were no such thing as a "Palestinian people" in 1947.
So when the UN declared in 1977 that November 29 should be considered an International Day of Solidarity with the Palestinian People, they must have had in mind the previous thirty years of cynical use of the Palestinian Arab cause by the Arab nations who never had any interest in their Palestinian brethren except as pawns to hurt Israel.
