I have noted many times in the past that when Palestinians say that "historic Palestine" is congruent with the borders of the British Mandate created in 1921, they cannot have too much history.
The Palestinian prime minister proved that yet again on Wednesday.
The Jordanian Minister of Agriculture visited the Palestinian prime minister Muhammad Shtayyeh in Ramallah, and Shtayyeh made a statement about the rich ties between his nonexistent nation and Jordan.
He "reiterated the spirit of partnership between Palestine and Jordan at all levels and throughout history, stressing that the two countries are partners in blood, history and unity of destiny."
Before 1946, Jordan was just a river. Before 1922, Transjordan was just a region - just as Palestine was before 1921.
Palestinians are no more descended from Canaanites as Jordanians are from Moabites or Ammonites.
So I suppose that Jordan and "Palestine" do have a history in common, in that until recently, they had no history.
