Who or what was the "new scare" or menace in america during the early cold war era?

The "New Scare" represented the communist threat to destroy the capitilist countries and bring them under their control.

Explanation:

Anticommunism is a historical phenomenon dating back to the nineteenth century, found in both Europe and America. It is present not only in speeches that preach the persecution of communists, but also in a set of ideals in defense of private property that pose communism as a threat to democracy.

Based on this context, the "New Scare" was proposed as a way of placing communism as a real and frightening threat. The New Scare preached that the communist countries, led by the USSR, could dominate and destroy the capitalist countries, setting up chaos and terror in those countries.

The image below is the cover of a 1947 comic book in the United States that uses the concept of "New Scare" to show a future where the country is dominated by communists.
