Judging by posts like yours, where we are in the US right now is deep in delusion. To compare the current situation in the US even remotely to the fall of the Carolingian dynasty shows severe lack of historical knowledge and perspective.
For one thing, there has been nothing that can reasonably be described as a coup. Coups involve serious violence (generally from the military), and we haven't had that. For another, we aren't at the point of civil war.
Honestly, by far the biggest threat to the stability of the country is the meme that the country is unstable. That sort of idea pushes people into taking drastic actions because they have to "save" things. But things are working ok (not perfectly), and if people start taking drastic action it will certainly hurt rather than help.
