EDIT: I can’t modify this to narrow the assertion to “… the US had a city (Cahokia) larger than its European contemporaries…”
Also, all of the Americas gets historical short shrift from the old world: my point still stands: there was a concerted effort 500 years ago to exterminate the natives, and the results of that plan continues to this day when people say “X doesn’t have any history”.
So, on one hand you acknowledge the concerted effort to exterminate the natives, and on the other hand you appear more than ready to ascribe the credit for the largest city on that soil to the USA? Isn't that just a little bit callous?
