Gonna get hate for this

Has America finally started decline? With so much internal division over a number of issues could this be the end of the United part? All great powers have a decline or a fall maybe America is headed for its own. Left and right constantly fighting a former president who almost triggered a major political and ideological shift to authoritarianism. Judges overturn things like they are trival matters which could have disastrous long-term implications.
Could this be it? The slow descent into chaos and divison which could see the states splitting up. I know theres a lot of nationalist pride here but you cannot stay at the top forever money and military power only go so far when you start to crumble from within there is little that can be done.
Rome
Britain
Persia
Macedonian
Eygpt
Chinese dynasties
All great powers
All declined
Nothing lasts forever
