@hersuit - historically there seems to be a bit of a correction happening.
After all: most of what is now the United States was inhabited by light-brown to copper-skinned people who were ethnically cleansed by white boat people who fled Europe's poverty and religious persecution and then proceeded to murder most of the native inhabitants of the country they 'took' as their own. Now the smidgeon of what's left of the former rightful owners of what we call the United States now, are at best tourist attractions, at worst also criminals, because they have been pushed to the margins of society.
Back to the recent past and our living memory: There is also the problem brought on by the U.S. of the never-ending and never-won wars in the Middle East which NATO, often without asking its European partners brought on, causing huge mortality, destruction movements of populations - i.e. a never-ending stream of refugees into Europe. What if Europe decided to send their 'migrants', 'refugees' caused by America's wars, off to America?
Mankind is on the move, also brought on by climate change, but, of course you Right Wing Nut Jobs 'don't believe in climate change'.
Lets see what we can save of humanity in the next 20 to 30 years without resorting to neglect and murder by neglect or intent. Can we save our humanity? Do people like Trump & Co even have the insight or humanity to think in global terms about humans?
