If you read your post, your making my case about how these kinglets are a threat and how they are controlled by the U.S and west
The GCC and Muslim world will never be free until this situation is changed
They are only a threat if they are deviating from the established policies and acting like trojan horses - as the current Abu Dhabi regime (MBZ) has been doing in recent years. While I am personally a big believer in Arab unity, as most Arabs are, and see no real purpose for the division of Arabia in the first place in an ideal world, we need to operate in the reality we live in.
You can say the same thing about the entire Muslim world. There are artificial divisions everywhere you look and regimes who are acting like trojan horses and who are only interested in their self-preservation. I can give you many examples from Africa, the Middle East, South East Asia, South Asia etc. but this would likely change the direction of this thread.
If the GCC was located in an irreelvant (geopolitically) region of the world, did not have one of the world's largest natural and mineral wealth on the planet, did not border some of the most important trade routes on the planet, did not have the religious, cultural, linguistic, historical etc. weight, we would not have the foremost superpower of the world (USA) so deeply ingrained in the region. It is simple geopolitics.
Even if Arabia was unified (or the entire Arab world for that matter), the US would still be around for those above mentioned reasons. Same reason why the British Empire and French Empires of the past tried and partially succeeded with their meddling starting during the Napoleonic era. Same reason why the Crusades occurred, before that Roman and Byzantine empire meddling etc. Geography another simple reason - Europe's largest border (maritime) is with the Arab world and people to people relations have occurred since Neolithic times (12.000 + years ago) which occurred in the Arab world before spreading to the rest of the world. In fact most Europeans, the majority of their DNA is originally from the Arab world. You can Google this or ask AI models. So even if we wanted them completely gone from our backs, this is not going to occur. Same way the influence was the other way around, Semitic Phoenicians native to the Arab world founding many of Europe's currently largest cities, civilizations native to the Arab world influencing Greek, Roman/Italian culture in every sphere, 800 years of Arab rule influencing every walk of life etc. The Mediterranean has acted like a high-way of mutual influences for millennia. Since Neolithic times as I wrote. We cannot escape this geography whether we like it or not.
Also do not forget that the US is basically an extension of Europe. Albeit demographics are changing making it more Latin in origin but even the Latinos are a mixture of local Indian tribes and Spaniards/Portuguese etc. mixed with some African admixture. Culturally, religiously and linguistically (Spanish) they are all an extension of Europe. Ironically the Latinos have been heavily influenced by Arab culture (Spanish is heavily influenced by Arabic), ethnically - Spanish and Portuguese people have 15-20% Arab/Moorish admixture on average - some regions even more, cuisine, architecture, music, culture etc. due to 800 years of Arab presence in Iberia. So another example of how interconnected we are.
That is why long-term planning and working towards unification in every way is the right policy. The GCC is a great tool towards that. It is also important to educate Arabs, regardless of nationality of the historical reality of our region and not for Arabs to be too attached to their current national states (while loyalty and love for your land and country should be encouraged) we must never forget the greater picture and the history of the region.
