I'm not expecting anything great from Trump at this point. But if he wanted to try something genuinely heroic, he could sacrifice his ego upon the fire of truth and admit he himself was bamboozled by the Pandemic of Lies. He then, only THEN could he show people the way out of the shithole he himself helped dig.
If Trump himself was swindled by it all, he just needs to admit it and he'll have gigantic waves of support to do what needs to be done.
I don't think he'll get the same support if he tells some stories that he knew all along but performed some kind of sting operation.
People won't be kind to him in that scenario.
