Why no Jordanian Arab Spring ...yet? In my opinion it's because if the Palestinian majority rises-up and takes power in Jordan right now, this would effectively turn Jordan into a de-facto 'Palestine' in all but name, thus severely politically undermining the Palestinians official UN recognition bid. I think that Jordans king Abdulla privately wants UN recognition of Palestine even less than Israel does, and for the very same reason. When/if Palestine is officially recognised, the Palestinian-Jordanians will then be able to overthrow the Jordanian monarchy 'Arab Spring' style without undermining the Palestinian state bid at the UN - which is based largely on the Palestinians not currently having a country of their own. Once this has been done, the Palestinians can then have either 2 (or even 3 including Gaza?) states, or one large one - encompassing all of Jordan and the West Bank as well.
