You can reasonably dispute the meaning of a lot Trump says because he’s so incoherent and inarticulate.
But what you can’t reasonably dispute is that he is a sadistic and delusional narcissistic sociopath, at once both psychopathic and psychotic, who is lacking in morality, conscience, empathy, remorse, and impulse control, and whose only concern if a city (in any country, including ours) were to be wiped off the face of the Earth, would be how it affects him.
