The closest you can come to a case of an 'unexpected' civil war that had a nominally first world country suddenly go apeshit and have a civil war is Spain.
https://en.wikipedia.org/wiki/Spanish_Civil_War#Background
Which had the civil conflict originating at least nearly 100 years ago and a military coup in the 1920s and a revolution a few years prior. It was unimaginably instable and nobody would have gone "We won't have a civil war".
That leaves us with an unending volume of banana republics with absolutely zero political stability to begin with, vaciliating between dictatorships and crony republics. Or flash in the pan moments like the Spartakists, or cases of war and revolution from an existing state in the midst of War (finland), or war and collaborators vs non collaborators (Italy in WW2).
Yugoslavia is hardly a suitable example when it was a not even 100 year old state deeply divided by geographical ethnic groups who spoke different languages, different religions, ect. Ukraine had a foreign invader propping up the rebels. It is not hubris to say the United States is more fucking stable than Mozambique and Tajikistan, and we're not going to suddenly overnight drop into a civil war. If one happens it is going to take decades upon decades of developments. And frankly given the more salient examples of Brazil, Argentina and Greece who went from Juntas back to democracy without third world gorilla tribal bloodletting?
Yeah, that's more of a prognosis of our situation than Rwanda, even if sometimes I think social media will be a radio rwanda in miniature for how histrionic and like teenage girls it makes Americans of all stripes.
