Why did anticommunist hysteria sweep the U.S in the early 1950s and how did it shape domestic politics?
Quick answer:
Anticommunist hysteria swept the United States after World War II due to American fears that communist governments were attempting to infiltrate the country. This hysteria intensified when communists took over China, the Soviets tested an atomic weapon, and communist forces invaded South Korea. It shaped domestic politics by creating a conservative anticommunist movement, compromising free speech and other civil liberties, and prompting U.S. involvement in the Korean War and the Vietnam War.
After World War II, the two remaining global superpowers, the Soviet Union and the United States, became intensely suspicious of each other.

Anyone who opposed McCarthy was declared disloyal. Americans became convinced that communists had infiltrated every facet of society. As a result, many innocent people lost their jobs, notably in the entertainment industry but also in many other fields.
Domestic politics were shaped for years by the fear of communist infiltration. The political climate became overwhelmingly conservative, as anyone who wanted to achieve success had to demonstrate that they were fervently anticommunist. Free speech and other civil liberties were negatively impacted because people were unable to say what they really thought for fear of being branded communists.
Abroad, the Korean War was fought to contain communism, and later, the United States entered into the conflict in Vietnam in an effort to prevent communism from overrunning Southeast Asia.
