I don't know about whether or not that is true, I've generally seen the American failures across the board as Gaunter O'Dimm said: the 'fault of our rotten natures.'
I think China has already defeated & neutered the US long ago. US economy is de-industrialized and economically & socially screwed up with 33 Trillion dollars of National Debt. US - NATO now looks like a paper tiger due to their failures in Middle East/ Ukraine to Asia and the Global South. PRC are rapidly gaining on the US military and plan on surpassing it all areas by 2046. They are obedient to authority and have a high work ethic. They have a far greater industrial sector than the US and also have hundreds of millions of highly educated and intelligent & ambitious people. If China continues integrating with Russia and become symbiotic like Canada & the US they will have solved their raw materials & natural resource problem.
The baby boomer generation destroyed America's future for medium term gains, fueled by massive debts. As things go I believe that in 500 years the 'Pax Americana' would just be a brief blip in history-less than a century, really not much in the grand scheme of human civilization.
