Bit late to explore that question with north America slowly sinking .
IMHO, much of today's troubles can be traced to the huge influx of Germans and their Prussian culture around the turn of the 19 th century , followed by the huge number of German SS who came in using Operation Paper Clip for access , at the end of WW2 .
America was then internally invaded . And from the moment that the CIA was run by the Nazis and the families took control of the agencies , information flow and pharmaceuticals , any days of US greatness were destined to be short lived .
Result is the German Fourth Reich is hidden in plain sight now with a move away from the Constitution to something outwardly liberal but actually bound by Fascist controls and a deep seated loved of Prussian culture -- expansion , control , subjugation .
It will be interesting to watch the Fourth Reich and China scrap with each other over what is now USA .
As China needs the middle west so badly to feed its population I guess they will largely prevail , with Reich HQ somewhere perhaps in south America -- Argentina again ?
