In a nutshell:
Arab Team Revolution Muslim Brotherhood (Turkey, Half Libya, Idlib, Quatar, Hamas, Al Quaida) allied with the Democratic Party in USA & Iran
Arab Team Conservative (SA, VAE, Egypt, other half of Libya) allied with the Republican Party in USA and how it seems nowadays Israel
The Arabs in Israel are mostly in team MB. If there would be free elections Abbas would be gone in a second and Hamas would take over. UAE knows this and is not really caring about them.This annexation thing is imo only a named fake reason for the open announcement of the formerly covered fact of normalization.
Egypt and Jordan have already relationships. Imo next will be SA. If the Syrians will be able to push Iran out one day soon normalization with Syria will be there also.
Imo Israel should risk annexation. The MB idiots and their allies will try to bring Israel down whatever it does. And the opposing camp will be happy about one enemy less.
