We know not to equate the governments' policies with people. Of any country. Don't worry about it.

I'd say as about the same kind of unwelcome as before. Fundementally the US traveller is the same kind of US traveller as before

But then I don't live in eg Portugal where the effect of US immigrants has been felt more strongly

Most Europeans can separate Americans from their government, but a person's views and behavior matter. Paying customers are always welcome but obnoxious ones, regardless of culture, might get an eye roll or worse.
