The US accepts immigrants from 200+ countries around the world with the top 5 being Mexico, Cuba, India, Dominican Republic and China. None of that has changed under Trump.

I think you got lost in the rhetoric somewhere.

Tariffs are just the US adjusting to reality which other countries are slow to do. Free trade died all on its own, because the pandemic showed that critical industries were hollowed out by free trade in a way that could be appreciated from a national security perspective. That situation was favoring China too much, so we need to unwind that some.

Tariffs already existed in many countries in practice, so it's not like the US reinvented modern tariffs.
