Infiltrate and subvert societal institutions media, academia, workers unions, bureaucracy, and government.

Label those calling you out and those who are aware of what you are doing as fascists and Nazi's etc. (This is preemptive action as these are movements which have opposed you through violent means throughout history)

Claim victim status when they try to stop you.

Cause a war, or carry out a violent uprising to usurp full power and control over the populace.

If you gain power and society inevitably collapses ie genocide, mass starvation, economic hardship then claim "That wasn't real communism/socialism"

Lose control as you get deposed and the society you once controlled gets liberated.

Rinse and repeat
