One sign of a communist revolution in the United States, as perceived by Americans living in cities, was the presence of labor strikes and protests organized by socialist and communist groups. These events were seen as a threat to the capitalist system and a potential precursor to a communist takeover. Additionally, the spread of communist propaganda and ideologies, as well as the growth of communist parties and movements, were viewed as signs of a potential revolution. The Red Scare of the 1950s in particular heightened fears of communism and its potential influence in American cities.
