The only reason that Jordan maintains any credibility of civilization is the absence of the massive ‘Palestinian’ population Jordan rejected decades ago. Should the Hashemite King allow the ‘Palestinians’ to be integrated into Jordanian civilization that civilization will cease to exist. The Arabs have cultivated the backwardness of the ‘Palestinians’ and sustained their poverty as the Arab solution to avoiding absorption of these primitive people.
Jordanians are palestinians. Jordan is Palestine. They try to obscure that fact in order to escape two issues. First, to escape their responsibility for the west bank and second, to obscure the fact that they are ruled by a royal family that is not palestinian. The royal family is from Mecca (not Saud, but from Mecca, they were the original kings of Mecca). They were given Jordan as a consolation prize when they lost Mecca and the Sauds took it over.
They did expel Arafat and his PLO, slaughtered them like dogs. Arafat himself was egyptian and his PLO were a threat to the Jordanians as much as to anyone else. But they didn’t expel the palestinians, they “are” palestinians.
Arafat’s claim to represent palestinians was an existential threat to the Hashemite king and they booted the PLO out with no mercy, which is when they went to Lebanon and took it over.
