And US absolutely has been xenophobic for years, by official federal policy. I'm really surprised you're not aware of it, but here's a small selection of examples:
- Both our elected and appointed leaders are white nationalists. Our president called all Mexicans murderers and rapists, said African migrants were eating random pets in a rural US town (they weren't, obviously, but it was intended to exacerbate xenophobia)
- Our federal government has a mandate using ICE to try to eject anyone with a Hispanic name from the country (has already deported US citizens based on being hispanic/latino). We even boot people seeing asylum, often exporting them to foreign prisons even if they've never had a criminal record. We have concentration camps now, filled entirely with foreigners, and people who have lived here for decades but were foreigners.
- We stopped accepting new visas from 75 countries. We may even expel you for social media posts we don't like, or for attending a protest that our citizens can attend. We increased travel bans for people from majority Muslim countries. H1-B visas have been rolled back to only the highest paying jobs, and you may need to pay a $15,000 bond. We also now collect and store foreigners' biometric data indefinitely.
- Let's not forget the tariffs on virtually all other nations, to say nothing of "America First" and the new "Greater North America doctrine".
