Egypt?
Egypt was a mini Syria until military took control it, killing & jailing how many people?
Yep. Egypt is marking 100 years of independence this year. And I hear you, Mubarak was not a good thing recently. The Arab Spring took its toll. Though I'd argue that wasn't much more severe than what the US has seen since 2020.
For the most part Egypt has been stable. And while there is still animosity between the citizens and the "ruling class" again I'd say the same is true in the US.
Calling it a mini Syria feels like a stretch, though. Syria is a disaster due to far too much foreign influence. Russian in particular stirred that pot. Egypt was almost entirely internal to itself.
Now "stable" is also a relative term. I'd call Egypt stable just like I'd call the US stable. That said, neither is perfectly so and I wouldn't argue if you said neither was.
But I'll also point out that in all three situations, the US, Egypt, and Syria, the dominant religion had little to do with it, though in each case religion was used a backdrop. What all three did have in common was a socially conservative leader that spoke in violent terms.
