Spot on. But why?

Because he doesn't care about those things.

He wants the Middle East to be orderly, for a variety of reasons. He wants a Peace Prize, he wants credit for establishing a regional cross security and economic agreement through the Abraham Accords, and he wants to make a shirt-ton of money while doing it.

He may share a bit of Dope's perspective on whether the populations of these countries are "ready" for self-governance, rather than being rule by monarchies or other semi-autocratic non-democratic governments. But he's also intensely transactional. Right now, all these countries are rule by autocrats and monarchs who are both willing to make deals with the U.S. (as a country) and him (as a private individual through his proxies), in a way that democratically-elected governments in those countries never ever would. Why would he want to change that for some hazy intangible ideal like "self-determination," which he (like Dope) probably doesn't think they're "ready" for anyway?
