I think reports on this need to be clear: this isn’t really supporting Israel so much as it is opposing Iran.
There is nothing in this statement, for example, that would recognize Israel’s right to defend itself from Egypt.
It is only because Iran is upsetting the Sunni Muslim status quo and Israel’s actions also indirectly benefit those same interest that this man’s statements have been made.
The very act of stating Israel has a right to anything is radical in Islam. Having Bahrain state this is the opening of a very sacred door. Also, Iran is Shia.
The article and you overlook the important point
First, president Trump received in Riyadh the red carpet treatment with all stops pulled and all the belles and whistles. There in front of all the Arab world he announced the fact that there was cooperation between America, the Arab Gulf States, Egypt and Jordan and Israel against the common existential enemy Iran. The visit was a magnitude 9 earth quake in the region
Although the alliance existed secretly for quite some time, Trump unequivocally made it public. When an official from Bahrain speaks, it is certain that he speaks for the GCC with the possible exception of total agreement from Qatar.
Also, you drag religion into it. In today’s Arab world there is another, perhaps more important factor. That is business, money. Iran covets the wealth and business and industrial ability and wealth in the GCC. Egypt sees the GCC as a source of both business and jobs. The Saudi Crown Prince has in effect cast of the primitive shackles of super fundamentalist Islam in favor of prosperity.
