The Palestine Post had this to say at the 25th anniversary, during the depths of the Holocaust:
Notice how even then, as Jews argued that the immediate establishment of a state would save countless lives from the Nazis, they still bent over backwards to point out that Jewish immigration to Palestine helped the Arab community and did not displace a single person. Notice also that even then it was assumed that the Palestine spoken of in 1917 included Transjordan. (See also my posting on Eastern Palestine.)
