I’d say most north eastern EU countries (Germany, the Netherlands, Belgium, most of Scandinavia) is safe right now. The Netherlands (where I live) has been right-leaning for a while now and even though it got worse this past election the focus is mainly on nationallism and anti-immigrant policies at the moment.
As a Dutch person we’d happily welcome the more sensible Americans over here 🙂. I can’t guarantee our government wouldn’t try to stop a mass migration wave given their anti-immigrant policies though.
It’s funny, my partner and I were actually talking about moving to the US for a while to spend more time with my American in-laws but I think that’ll be out of the window for the next four years.
