Using NSC-68, can you argue that Americans were worried that communists would "subvert" (to ruin or corrupt from within) American culture? Explain

mass hysteria and fear amongst the public

Explanation:

During the Cold War era, there was a mass hysteria and fear amongst the public that many communists from Soviet Union had infiltrated into the country and were attempting to subvert the American system.

Many newspapers and media outlets often published that communist individuals and spies, often called as commies, were attempting to destroy the American economy, culture, and political institutions.

The information contained in the NCS Paper 68 that institutions like labor unions, civic enterprises, schools, churches, and media have been subverted and impeded by the communists further created tensity and confusion among the Americans.
