🧠 Post-War: McCarthyism & the Red Scare (1950-54)

The Cold War created fear of communism at home:

Cold War context: USSR became enemy; Berlin Blockade (1948), Korean War (1950), fear of nuclear war

Senator Joseph McCarthy (1950-54): Claimed 205 communists in State Department — little evidence but huge publicity

HUAC: House Un-American Activities Committee investigated Hollywood — "Are you now or have you ever been a member of the Communist Party?"

Blacklists: "Hollywood Ten" and hundreds more lost jobs for suspected communist links

Rosenbergs (1953): Executed for passing nuclear secrets to USSR — showed real fear

McCarthy's fall (1954): Army-McCarthy hearings televised nationally — Army counsel Joseph Welch asked: "Have you no sense of decency?" — Senate censured McCarthy 67-22 in December 1954. Edward R. Murrow's TV expose (March 1954) also helped turn public opinion.

Exam use: Shows how fear can threaten civil liberties. Link to earlier Red Scare (1919-20) — recurring theme.
