Except that it will - regardless of the taqyyia - many muslims have said that there is no way that allah is the superior and only god if he allows himself to be nuked. (Allah determines everything down to the sub molecular so there is nothing he does not control absolutely).
No muslim will accept the humiliation of praying to 1) a failed god, b) to a radioactive hole in the ground. They have said that if the those places are nuked then they will convert to Christianity, Judaism of atheism.
The Saudis demolish everything and anything connected to Mohammad or came before which might contradict the 5 holy books.
The Shia revere the Kaaba and would take it if they could, but having their allah destroyed, humiliated and shown to be weak will have the same affect regardless of sect.
