This is how a narcissist admits he was wrong.
Let’s say he was wrong about trade deals. Wrong they were on balance bad for the United States. Wrong that new ones like the Trans-Pacific Partnership, actually offered next generation improvements on past deals. Wrong that an existing one like NAFTA was “the worst deal in the history of the world.”
Since he’s a narcissist (and let’s assume the person we’re talking about is a he…and the President of the United States, say). He can’t admit errors. He doesn’t believe he makes errors. Errors are made by the Deep State and blamed on him as part of their plots. So, instead what he does is, he attacks the deals, throws the world into chaos by withdrawing from them or threatening to, attacks our trading partners and their leaders, goes big with his initial but grossly wrong-headed beliefs. Then, at the eleventh hour, when his bad policies are about to flush the good economy he inherited from his predecessor down the toilet, he rebrands the bad old deal as a new one with a shiny new name, makes a few relatively modest changes, takes credit for it, and declares victory.
