I grew up in a tourism country and the number one rule of tourism is that if you want people to come hospitality goes a long way. A mad-king-leader calling them freeloaders and quoting Napoleon with "He who saves his country, violates no law" and a cult like followership doesn't exactly instill confidence that your rights will be respected when you go there.
The current administration seems to be downright hostile to everybody who isn't a US citizen even if we'd just come to spend our money in the US. Pair that with a lack of basic oversight over your cops/TSA-agents/whatever and suddenly the US just isn't as attractive any more.
Don't get me wrong, I find the US fascinating, but given I am in the middle of Europe, I have many destinations with a friendlier atmosphere and a more reliable political leadership to chose from.
