“General Mark Milley told The Atlantic that when he invited a wounded, wheelchair-bound soldier to sing God Bless America at Milley’s welcoming ceremony as chairman of the Joint Chiefs of staff, Trump admonished him. ‘Why do you bring people like that here?’ Trump asked, according to Milley. ‘No one wants to see that, the wounded.’”
Trump is disgusted by Americans who are not healthy or undamaged.
Americans, real Americans, disgust him.

I suspect he sees himself as the old decrepit man he is. Age angers him. It makes him bitter. This is why he wants to visit holy hell on those who oppose him or say a cross word about him.
It angers him that there are smart people in the world. He knows he is not smart, despite the comments. So he has to put others down (see quotes where he denigrates the intelligence of others and boasts about others saying how truly smart he is).
He KNOWS he is not the smartest in the room.
