I have a different explanation.
Trump is a narcissist sociopath who can’t possibly comfort another person because he fundamentally doesn’t give a shit about other people.
Your explanation gives him the benefit of the doubt and the tacit assumption that he has any humanity whatsoever. No offense, but fuck that. I find this an extremely dubious assumption, as I’ve never seen him do a single thing to justify this, including boasting, preemptively, that he has somehow done a far better job than previous presidents in this role.
