Yeah, it was called the United States and if it was an illusion it would not have been the weakness exploited in this way. America was real and can well be again: turns out allowing such diversity and multiculturalism gave rise to things like New York City, California etc etc. known for being giant piles of messy commerce and influence from all over the place.

It's never been any different, all the way back to when Germans or Irish or whoever were the 'demonized immigrants'. This is what made America great. Anytime we want it, those conditions can return. It was no illusion.
