In fact, the support given to Israel by the US government is different from the support given by some Arab countries.
I mean you cannot say that both of these two groups enjoy an authority in this game. The USs support can be rooted in many different things, while other countries' such as the UAE, Bahrain and Morocco which have taken measures to normalize ties with Israel is rooted in their desperation.
The reason is that these countries are worried that they are going to lose the support of a big power called the US, because the it announced that it is going to withdrew from the region.
Now, all these years, these desperate countries which have always relied on a foreign power to keep their system of government in place, are seeking an alternative power to rely on.
