Here's my logic:
A) Soviet totalitarianism was the best ever, having 75 years to perfect.
B) And yet, the USSR collapsed.
C) Union unrest in Poland is what applied the pressure.
D) Under that pressure, the Polish govt legalized unions.
E) Solidarity, the big new Polish union, began the flood of dissent.
F) Political infighting in the USSR broke out; there was a coup attempt.
G) The walls came down.
H) American totalitarianism is new, divided, and stupid.
I) American unions are already legal.
J) The tool for applying pressure is already here.
K) This should be easy, right?
L) The broligarchs are just itching to 25th amendment trump and install president Musk-Thiel-Puppetboy-Vance.
M) It can't be more than a few weeks before the broligarchs get frustrated and declare martial law (or marshall law).
N) I have lots more faith in the military's loyalty to the constitution than that of any maga or oligarch.
O) The military declines to participate.
P) Out of the chaos, progressive voices emerge, kick the Democratic gerontocracy to the kerb, articulate a positive vision of a liberal social democracy, the people rally to a platform that isn't just "us v them".
Q) America is pulled back from the brink by progressive voices.

Crazier things have happened.
