Are you in the U.S.A? I'm speaking from a European/UK persepective.
If you are not In Europe you may be unaware of how Trump, and now JD Vance, are being perceived. Even those who were understanding of all you say above about the situation in the U.S see Trump as a total loose canon, a bully, and disrespectful of long standing relationships and allies. And what is happening is that all sorts of groupings are uniting in opposition to his presidency, and certainly his style.
We've seen the Liberals in Canada, for example, being given a boost and making up ground in the polls. Before Trump was elected, the Liberals were going to be completely annihilated at the upcoming Canadian election...now it doesn't seem so certain.
If his election represented a re-balancing of matters which had gone too much to the extreme, then the manner of his presidency is creating another re-balancing - because of his extreme nature.
JD Vance comes across as utterly culturally ignorant - which is disappointing. I thought he might be a moderating influence. And Elon Musk is even worse.
All combine to make us realise here in Europe just how foreign the U.S really is, and how we don't share its culture. We always knew that, and resented U.S cultural hegemony.....but now it is becoming impossible to ignore. 'America First' really doesn't give a damn for its allies or its long term relationships.
