Trump loves to espouse this “Wildman” philosophy of negotiation where you remain as unpredictable as possible in the belief that this will give you some kind of advantage, but in reality what it gets you is this; a total lack of trust. When you combine that with a stated belief that mutually beneficial arrangements cannot exist - that every deal has to have a winner and it has to be you - it becomes functionally impossible for anyone to take you at your word when you say that you’re entering into negotiations in good faith.

Obviously, Trump’s “philosophy” aligns with his utter lack of attention span and inability to hold complex thoughts in his head in such a way that it could be read as nothing more than a convenient retroactive explanation for what is in reality just the chaos of a mind ill-suited to complex thought, incapable of restraint and driven entirely by id. If you were so inclined.
