Final answer:
The fear during the Red Scare II in the U.S. primarily revolved around the perceived threat of communism and the potential for leftist revolutions.
Explanation:
During the Red Scare II in the United States, people feared communism and viewed it as a threat to the nation's security and stability. The fear of communism stemmed from events such as the 1917 Russian Revolution, where the Bolsheviks took power, igniting concerns that a similar revolution could occur in the U.S. These fears led to actions like the Palmer Raids, targeting suspected radicals. The Red Scare also resurfaced in the 1940s and 1950s, known as the Second Red Scare, characterized by the rise of McCarthyism and heightened anti-communist sentiments.
