Looking at his well documented business failures , his inability to grasp basic economic concepts, as well as his complete lack of intellectual curiosity, him not having a well thought out, rational plan wouldn’t surprise many.
He isn’t playing 4D chess. He's doing exactly what he has done for decades, deluding himself into believing that he knows better than dozens of highly intelligent experts and centuries of historical precedent. There is nothing more dangerous than a leader that doesn’t grasp his own shortcomings, who lacks self awareness. Trump has never understood that he is a great marketer of himself, nothing more. Unlike Obama, Reagan, and Kennedy, he has never been aware of his limits. Those Presidents understood marketing as well, but they also hired the best and brightest they could get their hands on. Trump on the other hand, hires people that will tell him what he wants to hear.
