Apparently, a new movement led by Jordanians is aiming to do exactly that. From IsraelSeen, in an interview with Mudar Zahran, a Jordanian dissident:
Were the Hashemites not ruling the eastern part of Palestine then the Palestinians already would have had a country for sixty years and nobody would have pressured Israel to give away its land. Yet this is not the case and the Hashemites are ruling the place and constantly telling the Palestinians they are merely refugees.
However, the world will only change its views on the location of the future Palestinian state if it wakes up to the problem of Jordanian apartheid. via elderofziyon.blogspot.com
