One of the frustrating things with stories about trump is the nonsensical assumption that he is rational, or the posit that his mindset and actions are tricky to figure out.
Everything he does is so he can feel in control.
It's about HIS power.
Everything.
There's nothing difficult about this.
It’s a mistake to ask this question because it assumes Trump’s rationality.
He wants to do this because it makes him feel powerful. He doesn’t care if the effects are good or bad. Indeed, the more destruction he causes, or the more people fear destruction he may cause, the more powerful he feels.
