Looks like Jordan just became a very staunch ally in the region.
I don't know about that: There is a reason why 99.9% of Palestinians are also Jordanian. Palestine was carved out of Jordan when the State of Israel was created. Palestine never existed as a separate and distinct nation-state. Jordan was always the soil upon which Palestine rested.
An ally of the old US, but not the new remade Obama USA. Obama wants chaos in Muslim lands. It help to establish the Greater Caliphate. A stable Jordanian government is an obstacle to him.
