One possible path. Leftists continue to push and up the ante with more overt violence towards conservatives and more false flag operations used to justify it. Eventually some on the right have had enough and actually do run a few ops against the left. These are far more brutal, better conceived, and better executed than any of the BS the leftists have managed. The rats finally have their excuse, push for martial law and draconian measures. These are too much for a much higher percentage of freedom loving patriots who organize far more quickly and thoroughly than anyone on the left anticipated. Emboldened by a few key refusals to accept orders regarding arrests and or detention of American citizens by law enforcement and military personnel, the new American patriots take direct action to oust the growing leftist cancer at *all* levels. Violence breaks out nationwide. While the top tier leftists are reasonably well protected by well paid body guards (mercenaries in all but name) leftists at the local and state level suffer tremendous loss of life. Replaced by real Americans from the ground up, the leftist masters topple and flee their failed experiment. The cost is still measured in double digit thousands of lives.
My estimate is 60 million...we can’t even comprehend what angry unemployed engineers can create in their garages and work benches.( lots of old electronics around that can be repurposed) I see 60 million killed in a war that splits the nation in 3 or 4 sections. Might even involve tactical nukes since desperate tyrants will use extreme measures to keep their power.
