The US considers Europe to be hostile?
Partly. As in any relationship, this is not a binary, it is a composite, and has ebbs and flows. Lately the relationship has had ebbs, and with a new administration we can expect flows, but from lower baseline than at least since WW2.
The leader of the US threatened invasion of Danish territory, as well as trade wars, and some of his allies openly support movements and parties deemed extremist in Europe. That's certainly how you would treat allies.
Europe is occupied by the US, so yeah.
As with most things these days there seems to be a difference between the US as a whole which I guess still considers Europe and Canada allies, and President Trump who seems loyal to Putin and rather anti Canada and the EU.
You seen any of Trump's tweets in the last couple months? It used to be all about China but now he talks about Europe and Canada like we're enemies because he feels like the whole world should only do what he wants.
The current administration is not treating Europe as an ally. It’s pretty shameful.
But hopefully Europe becomes more independent. The US has become too unstable
