>I don’t know how the US charts a path back from all this.

There isn't one. And the sooner we all come to terms with that, the better off we and posterity will be. The constitutional government of the United States failed long before January 20th, 2025. Chasing sunk costs on this scale as futile, even if the alternatives are terrifying.

In my opinion, the best, just, course forward is a Constitutional Convention that dissolves the United States Government and replaces it with nothing. Let the states and territories govern themselves as they choose, and work out needed compacts and agreements going forward.
