What is bad is the limited and type of knowledge Trump relies upon. He is a cash flow investor of a small family business compared to the big boys like Marriot and large Casinos. He also believes that for him to win demands there is a loser. Humiliation is an unneeded part of his business equation.
This does not bode well for foreign policy or Allie formation. It also allows for corruption, lying and bribes to be part of his business model.
