No matter if one is pro-israel or not, there are reasons to not want your country to become an islamist country ruled by sharia (Jordan is partially ruled by sharia law).

And the second Arab country to recognise Israel [1]. (After Egypt. Also on the list.)
In June, Amman was probably "intercepting some of the missiles and drones en route to Israel, with debris from those interceptions causing damage in some instances" [2].
The Israel hypothesis does not hold for this list.
