Recently someone referred to Trump as "playing 4D chess", which in the context of our conversation felt like hand waving to absolve anyone of having to come up with a coherent explanation for Trump's policies.

It has since gone into my lexicon of thought-terminating cliches.

It's not that Trump doesn't have a coherent reason for some of his policies, but it very much felt like a dismissal of thinking along the lines of "His strategy is too advanced for us to know what games he's playing, so I don't have to explain it."
