Americans do not take the situation seriously. They either think they have no power to personally fix it, so contributing to any effort is pointless, or that it's just more of the same politics as before and can't tell the difference. They are encouraged to stay out of the way because they are the only force that seems to be capable of stopping it at this point.
Once Trump and the GOP destroy the framework of power the constitution defines, there are no rules anymore, only power, and the constitution really does mean nothing. The relationship America built with the world since WW1 will be over and won't return as democratic nations can not remain interdependent with a fascist America. America will be another authoritarian regime using violence as the solution to every problem, including domestic problems. Those problems will only increase because an authoritarian leadership is functionally incapable of managing a non-authoritarian system. America will transition, painfully and violently, to a fascist state and the dream that was America will be dead. All at the hands of a TV show personality and the generations raised by TV, which is both sad and painfully American.
Edit: Not enough Americans...
Just be a part of a group who are trying. That's it. Nobody needs to action hero a solution with a fist fight finale.
