“Our best bet is that he will be as incompetent at destroying the nation as he is arrogant. “
That is a reasonable hope, if not even a prediction. In his arrogance and hubris, he does not understand what America is, and America is not over.
He'll end up like Balaam, inadvertantly blessing the nation (even if through extreme travail and trauma). Despite his malevolent schemes and aspirations, there is a substance and spirit that is America which is simply beyond his ability to curse and destroy. He's too self-absorbed and greedy to get that. At least Balaam had an epiphany. This spawn of Satan loves darkness too much to ever have a light go on.
