Those maps are misleading. They give the impression that they represent the borders assigned to a Jewish homeland. That is incorrect. They show the borders of the British Mandate for Palestine in 1918 (the first map) and in 1922 (the second map) after the British split the zone into two administrative areas (Palestine and Trans-Jordan).
The putative Jewish National Home was to be created somewhere WITHIN those maps but the frontiers of it were never defined in either 1920 or 1922.
They are not misleading... if you take the time to read the captions.
