When historians look back on this period of American history, they will say: so sad, an empire built on human freedom, devolved into a tyranny of perversion and political control, built on a mountain of printed money and debt.
The US was never going to last forever; the only question was timing and proximate cause. We are now able to recognize the emergence both.
Like Rome, the US has its natural inconsistencies, but a dynamic and resilient society is able to adapt and change. However, the growing problems become manifest when internal (domestic) enemies perceive an advantage from destruction rather than reform.
What I find interesting is that while many/most focus on the decline, like newborns, there are constantly new developments taking place. Because they are not (yet) broadly known, they do not warrant attention until success makes them subjects of the historical record.
For example, while Rome was falling, the church was in ascendance. While the US is falling, virtual societies based on AI, advanced genetics and virtual reality may make nation-states obsolete.
Societies in ascendance are always patrimony based on logic, ability & results. It's a sure tell a nation is in decline when it loses focus on (scientific) progress and becomes focused on internal, emotion needs and wants.
Don't cry for the US; rather, focus on where the action is.
