The most baffling thing about the peace process always appears to be (mostly western, fairly progressive) Jordan...
Until you recall what the Jordanian Royal Family needed to do to the PLO to maintain control within their own nation.
At least the Jordanian Husseins have been able to govern well, unlike the Assads to the north or their (extremely) distant cousins to the east...
Jordan’s Royal Family are Hashemites - descendants of the Prophet, who have a variety of traditional cultural structures that support their legitimacy. They are well ingrained to the tribal organizations, that still exert considerable influence.
The Assad’s are members of a relatively small (Alawite) minority, whose basis for ruling rests on their Arab racial collectivist ideology (Ba’athism, akin to Nazism). Assad has to rely more on oppression than the Jordanian King.
