Yet if my memory serves me correct, the orginal plan was as planned by the early UN to divide the country, on the left of the Jordan River Israel, Jordan or Trans-Jordan on the right side of the Jordan in the years 1946-47.
The sad reality is that, despite Jordan fighting to keep the Palis out, the majority of folks living in Jordan are of that heritage. Frankly it is an effort not to become like what happened to Egypt during the so-called “Arab spring.”
Jordanians have no common heritage with “Palestinian” Arabs.
