I don’t think this would poses much of a additional threat, as the US legal system already appears to operate largely arbitrarily.
I think it’s highly likely that Trump will pursue, deport, or detain other genuine political opponents who are US citizens on the basis of their heritage anyway. Therefore, I assume that this will be a thing regardless. The only difference with Musk would be that even the super-rich would no longer be safe - but hey, I’m sure that the courts will continue to make exceptions for people with deep pockets anyway.
That’s true, of course — I completely agree with you. It’s just that, with all the news from the US that I read every day, I’ve unfortunately become quite pessimistic.
I’m keeping my fingers crossed that things will turn out alright after all.
