Two things, UAE should have realized before falling for such a trap aka alleged peace deal.... Israel will continue with annexation (read Natanyahu) and it was stopped for the time being way before deal happened even though, UAE claimed otherwise (Sorry to say). Secondly, they have succeeded to establish a strong root of spring in the region starting with UAE that sooner or later, people will rise against Royals and you have lost it way before start of their success.
You could have it all way before signing the deal, through other diplomatic offensives but seems like particular leadership was too weak & afraid of rebellion from inside hence, needed USA which conditioned support to acceptance of Israel while in the end, it is UAE to loose by one way or another. These wolves now needs no movement or spring for anti UAE rebellion because, Muslims themselves are going to rise against such a short sighted & weak decision and in the end, purpose is done.
