McCarthyism, characterized by rampant anti-communist sentiment and fear during the early Cold War, significantly shaped U.S. foreign policy by prioritizing the containment of communism globally. The intense scrutiny of alleged communist influences led to increased military and economic support for allies resisting communism, such as in Korea and Vietnam. Additionally, it fostered a climate of suspicion that influenced diplomatic relations, often leading to interventions based on the belief that any perceived communist threat needed to be countered decisively. Overall, McCarthyism solidified a hardline stance against the Soviet Union and its allies, impacting U.S. actions on the world stage.
