To be clear, I don’t think there is any threat from the US welcoming many more refugees. The US is very large and is fairly good at integration and the welfare benefits aren’t generous enough to attract many of those who are unlikely to contribute much to society.
It’s a completely and utterly different story for small-population, demographically-declining countries like Sweden.
In other words, the US can take a million refugees in no problem, even if their anti-Englightenment beliefs make some areas of some cities worse.
Sweden cannot take a million anti-Enlightenment refugees in and expect to survive it long-term. It just simply cannot. The same is true for many other European countries.
Sweden will not be a good place to live in 30 or 40 years, especially for women. The same might be true in many other European countries in the medium term.
The US faces no such threat, at least not from refugees. Climate change, now that is a whole different story.
