I think this misses how Trump thinks.
So little regard for how it would feel to his countrymen? He seems to think his countrymen love this! He has a ton of regard for how his countrymen would feel; the problem is that he's surrounded by people who shield him from knowing.
#Trump operates in a very shielded and coddled world, and that's key to so much of what he does.
So often his actions are a reflection of his being intentionally shielded from facts.
